How to change the hub of the rear wheel. What is the rear bearing of the hub, how is it arranged and how to replace it? What to cook for dismantling

Sometimes, before the upcoming trip, the passengers have to hear such expressions "the main thing that the wheels would not fly away, but in fact no one invests serious meaning in these words, and in vain.

This may well happen! Bad fasteners and worn items do not best affect the provision of safe movement, so it is very important to identify and eliminate the problem that appeared, even if, at first glance, it seems insignificant. For example, many drivers do not belong to due responsibility to the diagnosis of hub bearings, despite the fact that this item is an important element Rotating mechanism car wheel. About the characteristic signs of the hub breakdown and the way to replace it, we will tell you in today's article.

1. How to learn about malfunctions in the hub?

The hub is an important detail of any vehicle. It has a hole created for the possibility of its nozzle on the axis or the shaft, and the main purpose of this part is the transmission of torque from the crankshaft to the wheel, so that the latter starts to rotate and the car comes into motion. On a row with a hub, an equally significant element of the chassis node, the hub bearing presented as a double row ball or single row rolling rolling bearing. Together they are aimed at compliance with security measures in the process of moving the car, so it is clear that the failure of any part of them will not be able to guarantee this.

Today, the hubs of the rear wheels of any car are influenced by significant vertical and axial loads, and on vehicles with rear or fully drive This is also added to the big torque.

Unconsciously, to contribute to the rapid wear of the hub bearing can be the owner of the car during the replacement of the wheels. Spinning fastening bolts, you can not calculate strength and disrupt them, but it does not mean at all that it is not worth a well fixed the wheel drive. In this case, it is important to find the "golden middle" and then do not have to think about possible consequences. To tighten the bolts, it is best to use an electric wrench, as it is better "feels" the border of the permissible effort.

Affects fast wear Bearing node ( rear wheel) And moisture with dust falling into it from the road. Penetrating into the hub, dust works as an abrasive substance, gradually squeezing the lubricant through sealing parts, as a result of which the hub bearing is destroyed from heating.

It is easy to notice the need to replace the hub bearing, you will tell you a typical knock, which comes from the back of the body, is increasing when driving around uneven roads or at the occasion of hubs and pit. If the car moves along a flat surface - it arises hum and, even though it is not noticeable, the brake drum is very hot. Also, turning the steering wheel, quite often noticeably uncharacteristic slow motion - another faithful sign of faulty bearing work.

Usually, to determine the cause of the bearing breakage, there is little visual inspection, it is also necessary to take into account the condition of neighboring parts, the amount (quality) of lubrication and the conditions for using the vehicle.

Among the main factors affecting the failure of the bearing rear hubAllocate:

Reduction of parts resource due to long-term operation in extreme conditions (the average service life of this type of bearings is estimated by approximately 10,000,000 km., That in reality it often does not correspond to this indicator);

Insecurity of lubricants: their excess (flaw) or poor quality (70% of cases);

Pollution, when moisture or solid particles of various garbage fall inside the part (18% of cases);

Incorrect Wheel Installation: Incorrect Adjustment, Understanding Extension, Tightening Sleeves, Overheating, Increicable Clearance I.T. To avoid expensive breakage and compliance with precautions, manufacturers recommend checking the wheel bearings with each replacement of the brake pads, despite the age of the vehicle.

2. Check if the rear wheel hub bearing is needed

Most often the causes of the bearing bearing of the rear wheel hub are only two: the poor quality of the road surface (in some places it is generally difficult to name dear) and the poor quality of the materials of the Details itself. In these cases, when signing signs of the need to replace the rear hub, it is worth producing it. This process is simple, so you can perform it yourself, at home. But before proceeding to work, it is necessary to know exactly whether the whole thing in a faulty bearing or maybe there is another reason.

To do this, you will have to use the jack and lift the rear axle. After that, the wheel in which the hum is heard, rotate and rock to check the backlash. If it is discovered, and when performing rotational movements, a deaf tapping or hoarfront is heard - the bearing should be immediately changed, since it can damage the remaining parts of the hub system during the movement of the car.

One of the criteria for success when replacing the bearing of the rear wheel hub, is the quality new Detail. To all lovers to buy "cheaper", it is worth remembering the saying "I pay twice." Require from the cheap and poor-quality bearing for many years, the serviceable service is definitely not worth it and it is quite possible to soon have to make a similar purchase (God forbid that would only this detail).

3. Step-by-step instructions for replacing the rear hub bearing

At the preliminary stage of replacement, it is necessary to prepare the appropriate toolkit. It includes: a jack, a set of screwdrivers, a balloon key, a puller for the hub nut, a litol, a mount and chisel (the latter may not come in handy, but it is better to be at hand).

The direct replacement step includes the following points:

Putting a car to the first transmission, with the help of a jack (lift) raise it rear part and reloading the fastening bolts, remove the desired wheel from the hub (in the case of the use of a jack, so that the machine does not ride in front, under the front wheels should be put on special backups called "shoes");

By revealing the guide pins remove the brake drum (although they are usually just knocked), and followed by brake pads;

The nave fastening nut is unscrewed by a special puller (before that it is removed from it), and the hub itself is knocked down from the pin. It must be removed along with the ring of the bearing, and if it did not work out, this detail is dismantled with the help of chisel and mount during the hollowing and pulling. This process is quite long, so you should be patient;

Pressing the old bearing. For this, special forceps need to remove the locking ring, and then knock the metal boot. If, during the "spiritual" work, the hammer and chisel the edges of the hub were strongly repulsed, except for the new bearing, it is necessary to purchase a new hub, so the further serviceable work of "crippled" falls into question;

A new (or old) hub is lubricated with lithol and with the help of a special puller, the replaced bearing is pressed into it. Note! To clog it with a hammer very undesirable, in order to avoid damage.

At the same place, a boot and a locking ring are installed;

The hub is worn back to the pin, while tapping a little on the inner ring of the bearing, after which the pin is delayed, and its sides are harvested as much as possible;

Ultimately, brake pads, drum and finally the wheel itself, are installed in place. There is also a number of recommendations, to obtain the optimal result of the work:

What to avoid damage landing The rear hub bearing should only be used by professional puller specially designed for this, given the desired diameter of the clip.

To improve the installation process of the new bearing and the gland, press the press of various types. Apply the shock method of pressing new parts (for example, with a hammer) is extremely recommended. It can damage the seal of the gland and it will begin to skip the lubricant, and will also create a microcrack bearing in the bearing, because of which it will be harder and, accordingly, will fail to quickly.

Collect the rear hub node should be in the reverse order, after which the pump is removed from the method brake system And adjust the parking brake.

On some models, the rear hub bearing can only be replaced with a hub.

It is better to immediately change the wheel bearings of both rear wheels, as they are subject to the same load and wear out just as well.

The wheel bearing, brake drum and wheels disk, transit movement, braking, car wheel control, ensuring the safety of the driver and passengers. Replacing the VAZ 2109 hub is quite possible with their own hands, if there is all necessary materials and tools.

The time standards for replacing the hub, according to those, for VAZ 2109, are 27 minutes when the wheel is removed. To change the rear hub will help this instruction with a photo.

How to determine the fault of the suspension and hub

A sign of the replacement of the hub on the VAZ 2109 may be loud noise Or knock while driving. But this is an unreliable source, since the causes of the arms of the knock may be somewhat: the planks of the handbrake can also knock, brake pads, silent blocks rear rates. It's hard to guess.

To say more precisely, you need to take a jack, raise, twist, flaw and check. The hub bearing is usually not knocking, but it can give a buzz and vibration on the body. A knock, and rather strong, it will only require the replacement bearing.

Check the status of the bearing It is easy - the jack raise the necessary direction, turn and tent a wheel if there is a hum - the bearing to replace. If there is a backlash, check the tightening of the hub nut and wheel bolts.

It is not allowed to remove the backlash in the bearings of the hollows of an excessive tightening of nuts. The torque of the fastening of the hub of the front and rear nuts should be: nut bearing bearing rear wheel hub 186,3-225,6 (19-23) N * M (kgf * m), nuttur bearing nut front wheel 225.6-247.2 (23-25.2) N * M (kgf * m).

When replacing the hub bearing, be sure to inspect the hub if the new bearing on it will be installed very easily, then such a hub must be replaced with a newotherwise she will hang out. And despite replacing the bearing, provoke vibration and knock.

In the hubs of the front and rear wheels, ball-row-row bearings with seals are used that do not require replacement of lubrication and adjustment during operation.

When the hubs are expeded, the bearings are destroyed. Therefore, the extensive hubs must be carried out only in cases of increased noise of bearings or a significant increase in the gap in them: more than 0.015 mm - in the front and more than 0.030 - in the rear.

When choosing a hub bearing, it is necessary to know its dimensions:

• bearing size of the rear hub VAZ 2109 - 60 mm ( outside diameter), 30 mm (inner diameter), 37 mm (width), catalog number 6256706Е1С17;
• bearing size of the front hub VAZ 2109 - 64 mm (outer diameter), 34 mm (inner diameter), 37 mm (width), catalog number 2108310302001.

The price of the Bearing VAZ 2109 - 600 rubles is relevant for Moscow and the region (spring 2017).

To replace the hub VAZ 2109 it will take such an instrument:

• jack and balloon key;
• the end key is 30 mm and a long tube on it;
• passatii for removing locking rings;
• simple passage or cape key "at 12" (to unscrew the rear brake drum guide brake pins);
• wooden bar and hammer;
• chisel and montage;
• universal puller for extracting hub or reverse hammer;
• new hub on VAZ 2109 with article 21083104014 or 21103104014.

At first, it is necessary to open a chisel or dumplings to open the bin nut of the hub bear.

Then take the head "at 30" ...

... and weaken the nave bearing nut.

Weaken the wheel fastening bolts.

Subdominate the car. Tighten hand brake, turn on the first gear and substitute for the shoe wheels. Remove 4 wheel fastening bolts and remove it.

The key "at 12" we unscrew the two guides.

If the guide is not unscrewed, with the help of the hammer it is necessary to "shake", gently knocking.

Remove the brake drum.

Install the reverse hammer on the hub ...

... and remove the hub.

Take a new hub assembly.

An important detail of the chassis of the car is the wheel hub. For her free rotation on the axis, the bearing is placed in it. During operation, it is cut and becomes necessary to replace the hub bearing. The signal that the hub bearing is worn to serve as a crunch, vibration and deviation of the car from the course with a straight line movement.

Why the bearing in the hub

On the flange hub is attached wheel Disk or directly rim wheel. It also establishes the elements of the brake system. If the wheel enshrined on the hub, it acts as part of the automotive transmission. The front rotary wheel hub is an element of the steering. The diameter of the hub is much greater than that of its inner opening, where the bearing is pressed. Its length usually exceeds the diameter of this hole.

High strength and design hub does not require it frequent replacement. At the same time, the replacement of the hub bearing pressed into it must be made more often. This detail keeps together with the other such bearing weight of the machine, providing rotation of the wheels. In the hubs of slave axes not experiencing heavy loads, conical single-row bearings are usually used. For the driving, conical bearings with two rows, which are withstanding twice as large load than one-row.

The wheel bearings have a closed design, which involves their use until almost complete wear. They do not need to replace lubrication. However, the timely replacement of the hub bearing is necessary, first of all, because it provides a safe movement, under the action of serious radial and lateral loads.

When it is necessary to change the bearing

The hub bearing directly affects the ability of the car to move confidently on the road, without exposing the dangers of people in the car and beyond. If at least one of these bearings fails, the risk of uncontrollability of the car and emergency occurs. To understand on time, you need a replacement of the hub bearing, it follows every couple of weeks to swing each wheel to detect the backlash or outsided sounds.

Loyal signs that it is necessary to replace the hub bearing, are:

• detection of a noticeable backlash in the wheel when swaying it in different planes;
• the appearance during the movement of the monotonous grouse emanating from the wheel;
• owning or noise that disappears with a sharp turn;
• hot to the touch hub or her cap.

The causes of such phenomena may be lubricant loss due to high temperatures, Washing, if the car often overcomes water obstacles. A small sand and dust having an abrasive effect can get into the bearing housing.

In any option, it is worth thinking about how to change the hub bearing. After all, its wear is also affecting the batting of the steering wheel when the car is moving. Usually this procedure is carried out after 110-130 thousand km. Run. However, this indicator may vary depending on the operating conditions of the machine and the style of its driving. It is believed that every fourth car with mileage over hundreds of thousands of kilometers requires special attention to the state of such bearings. To prevent problems with them, it should be done by the rule for car owners regular diagnostics of hub bearings on their own or using the services of the auto service.

It is important to remember that attempts to repair themselves or how to replace the hub bearing, they will not lead to anything good, because it is not repairable. When dealing with it, you just need to replace it.

What you need to replace the hub bearing

To replace the hub bearing with their own hands, you need to be extremely careful and not to overestimate your strength. In a hundred, it is much easier and faster. Most of these enterprises operate experienced masters who use professional tools in order to knock out the bearing from the hub.

After making the decision to carry out work on your own, it is necessary to answer the question of how to remove the hub bearing and how to put a new one instead.

To do this, cook:

• new bearing, preferably European production, retaining rings and nut nave;
• hub schema and detailed instructions for working;
• premises for repair with vice and good lighting of the repaired assembly;
• special device for removal of the bearing;
• set of keys and heads with gate;
• the rounds that may be needed to remove the locking ring;
• lubricant (lithol);
• cut pipe length up to meter as lever.

Before starting work, we should think in detail how it is better to remove the hub bearing. By doing this for the first time, it is better to invite assistant. Special attention in the preparation deserves the puller of the hub bearing. With it, you can carefully remove the bearing without damaging the wheel and other parts of the machine. With his device and the principle of work it is better to familiarize yourself in advance. Usually such a hub bearing puller is a fairly simple device.

It is based on a metal rod and two or three metal paws connected to it. Their ends bent inside. Paws are conveniently moved to the rod for convenience of capture. They can be deployed to remove the bearing or other details. Using the hose bundled in the kit, the damaged bearing is removed easier. To remove the supplied bearings to the service station, it can be used as a mechanical so hydraulic puller for removing the hub bearing. Working with a device for removal of bearings requires care and accuracy. Here, the sledgehammer and the depicting is not allowed, because The landing place on the hub may be damaged.

Replacing the front hub bearing

Solving how to replace the front wheel bearing, its location should be taken into account. After all, it is the front suspension - the main part that affects the controllability of the machine. Therefore, it is better to do this work using the puller who helps to remove such a bearing without any problems. First of all, you need to fix the car in a convenient position. Put on the first transmission and put the stops under the wheels, tighten the handbrake.

Replacing the front hub bearing requires careful preparation of the working area. It should be carefully examined by the details with which it is necessary to deal, estimate how best to remove the bearing, prepare required tools. It should be taken into account that two bearings can be installed on the front hubs.

To replace the hub bearing on the front wheel, you need:

1. With a screwdriver, remove the bearing plug from the front wheel and open and relax the hub nut.
2. Sit down the wheel.
3. Caliper tie to the pendant details to eliminate it on the front brake hose. After that, squeeze it with a screwdriver and remove with swivel fist.
4. Unscrew the brake disc bolts from the hub and remove.
5. Screwdriver to make a locking ring and remove.
6. With the help of the puller, the hub bearing discharge.
7. Inspect the landing place of the bearing, clean it from corrosion and dirt, old lubrication, apply a new lubricant.
8. New bearing, not allowing its skew, pinch in the hub using the puller.
9. Put a lock ring.
10. Bearing to secure on the axis by a stubborn washer and nut.
11. Tightening the nut to adjust the rotation of the wheel to exclude the backup.

After completing the work, make a trial check-in to check no noise in the bearing. After that, once again check the availability of the backlash in the steering control. There are other ways to replace the front hub bearing. The deduction method can be used by trimming a suitable diameter pipe, the heating of the hub, etc. They require attention and caution.

Experienced auto machines know how to replace the rear wheel bearing. This procedure is much easier than when replacing the front. The hubs of these bearings on the rear independent suspension are almost the same as the front. The difference is only in the absence of a swivel fist. The type of bearing may vary depending on the machine model.

Replacing the rear wheel bearing

Before replacing the bearing on the rear hub, you need to take off the wheel and brake drum, unscrew the hub nut. Brake pads You can not touch. After removing the hub using the puller bearing, remove from the landing site. Replacing the rear hub bearing is carried out after a careful inspection of the hole in which it was, its purification, removal of possible sowing.

The hub must be cleaned from dust and dirt, old lubricant. The rear wheel bearing must be replaced only after performing these procedures and lubrication with lithol of the landing place of the bearing. To do this, it is necessary using the puller the bearing to press until it stops and put a locking ring. Mount the entire node in reverse order. Restantly filled with lubricant landing place bearing. Close it with a cap planted for sealant.

Replacing the hub bearings on different cars may differ. Cars of contemporary brands can be equipped with various easily damaged electronic devicesIt should be removed when replacing the bearing. Therefore, if you are not a highly qualified automotor, this work is better to entrust the masters of the car service.

It is also worth making an alignment after replacing the hub bearing. The exposed gathering collapse will improve the road keeping the road on the corners and direct, remove the vibration, as well as reduce the wear of the tires and fuel consumption. Still vibration can appear due to the crookedly inserted bearing. To eliminate it, you need to repel the bearing and check the tight of the wheels.

The wheel bearing is one of the important components of the chassis of the car. Sooner or later, before each car owner, the question arises about the need to replace this element due to its failure or end of operational resource. It should be sorted out how to diagnose the hub rear bearing malfunction on the VAZ-2110 and correctly replace it.

The manufacturer recommends changing these details every 100 thousand kilometers traveled by a car, but only in rare cases they spend their resource completely. Much more often they come into a faulty state about 1.5-2 times faster. In many ways, the wear rate depends on road Conditionsin which the car is operated, as well as from the manner of driving its owner. Naturally, a lot depends on the quality of the bearing itself.

Signs of malfunction

The wheel bearing has a big margin of strength, but since the loads that are constantly experiencing on them when driving are very high, sooner or later it is worn out to such an extent that it loses performance. It should not be tightened with the replacement of a faulty hub bearing, as it threatens what it will fall apart during the movement. This will inevitably lead to the instantaneous blocking of the wheel, which when driving at a sufficiently high speed very often becomes the cause of a serious accident.

If you don't even get into an accident, the operation of the machine with the non-working bearing of the hub will gradually lead to the failure of the entire rack, and its replacement is a process much more complex and expensive.

On the faulty state of the hub bearing can be judged by the appearance of foreign sounds during the movement - knocks or buzz from the side where it is located faulty detailwhich after a while, if you do not take any measures, go to the vibration, which goes into the steering wheel, and in the body part. This sign is already taking a serious threat - if it came to vibration, during the near future we can expect the collapse of the "killed" bearing with all the associated problems.

Procedure for diagnostics

An independent check of the hub bearing is performed in the following order. It follows, in turn, subdominating the left and right side of the vehicle, unwind the wheels.

Having found a wheel, publishing a root during rotation, it should be shown in different directions. As a rule, the backlash is quickly detected. In some cases, this is caused by a slightly tightened nutic nut. To eliminate such an opportunity, it should be pulled up with a dynamometric key and correct. If the backlash and extraneous noises disappeared - the hub bearing should be replaced.

Since the VAZ-2110 has been removed from production for quite a long time, it cannot be on warranty. This car is not equipped with too complex electronics, unlike many foreign cars. Therefore, possessing necessary tool And some skills, replace the hub bearing on the "dozen" can be independently.

Choosing a new detail

Buy a new hub bearing is now no difficulty, but since the choice of any details is very rich, decide on the manufacturer is not easy. You can advise to give preference to an element produced in Russia. The quality of bearings produced in China is inferior to domestic, and from their purchase should be abstained.

Procedure for replacement

It should be noted that the nut of the hub is tightened very tightly, and shifted it hard. To facilitate this task, you can use a metal pipe as a lever. Chisel and montage can also be useful - it is better to keep them nearby. Very good if producing independent replacement This element will first help an experienced motorist.

This procedure is performed in the following order. First of all, the car should be put in the garage equipped observation pit. If there is no such possibility, then you need to find a flat site for production repair work. Then the lever is included in the first transmission, and under the front wheels to put anti-tart stops (conventional bricks are suitable). Having done this, with the help of the key, the "spray" should be somewhat weakened by the wheel bolts and lift the side on which the hub bearing, jack, will change.

Then the fastening bolts are unscrewed to the end, and the wheel is removed from the axis. The guide pins are dispersed, and the brake drum is removed.

If it is impossible to do it right away, you should take a hammer and, applying a small planker to the drum, to obscure it around the circle.

If the inset does not give the result, you can try to complete the pins in your place - sometimes the drum after that leaves. In case all the methods proved to be ineffective, the part must be dismantled using the puller, however, there is a serious risk of damage. If this happens, the brake drum will also be replaced with a new one.

The hub nut is unscrewed using an end key and (if necessary) a metal pipe.

Nut of the hub is removed from the trough using the puller

You can try to remove the hub and without a puller. For this you need removed wheel put on the place again, and then drag sharply (but you do not need to dilute too much, otherwise the car is torn off the jack)

In the case of good luck, the bearing is removed along with the inner ring. If it remains in place, then with the purpose of dismantling it is necessary to use a small puller.

If the ring is stuck, then you need to move it with the help of a chisel and mount, after which it is used to use a tighter puller.

The locking ring is removed using special forceps or pliers, after which the boot is knocked down (it can not be removed if the bearing will be dismantled by knocking out).

Then the bearing is pressed (or simply knocks out).

Old lubricant It should be removed by laying a new one in its place. Then the new bearing is pressed (according to the rules it should be done using the puller, but in the case of its absence, the outer clip of the substituted element is suitable).

Wheel hubs car - indispensable parts of it. On both sides, they have two holes: for planting wheels and landing on the shaft. Before considering the question, how to remove the wheel hub, let's deal with what it comes into disrepair, and when does she need repair or replacement?

The hub is removed mainly when replacing bearings and other worn spare parts. Rules for removal and installation in most cars are the same. But there are some brands, with deviations of the dismantling process. Deviations depend on the concern that has released a car. Performing any work should not forget when repairing the machine.

The main function of the hub - transfer torque from the axis crankshaft to vehicle wheels. It also serves as the basis for fastener brake discs. On the bearing itself, the wheel rotation process takes place. It follows that the main nodes of the entire chassis of the car, ensuring safety when moving, are provided with a hub bearing and hub.

The malfunction of this part sometimes occurs at the time of replacing the wheels: if you drag the hub bolts on the wheel a passenger carThey can be disruptable. Hearing an uncharacteristic hum in the bearing, know that the item requires a replacement or repair. Wheels should be screwed either very, nor weak, look for the border. It is best to make it an electric wrench. He will not let you down. The wrench with ease will find, the very "golden middle".

How to independently remove the hub of the rear wheel?

Remove the hub of the car wheel, having a certain experience, is not difficult. It is important not to forget that the bearing from the hub is a rather fragile detail and when tightening it is worth counting the accompanying efforts to avoid damage. How to remove the rear hub?

Making the replacement of the hub, should first be:

• raise the car to support (submersible tripods or jack);
• remove the decorative disk cap;
• unscrew nuts fixing wheels;
• remove brake drums (in case of their presence), as well as brake discs, brake caliper (if on rear wheels car brakes installed);
• you should turn the flange combining the hole of the hub with all the available bolts on which it joins the bracket and unscrew them;
• it is also necessary to unscrew the bolts on which the caliper is attached;
• unscrew the fastenings of the swivel fist;
• unscrew the fastenings of the guide brake pads.

The next step will be removed the hub itself. Dismantle it through brake mechanism And it is very simple to extract. But it is possible to remove it from the bearing when the automotive system of brakes is not installed on the machine. However, no special tools do not do here, and you will have to visit the service maintenance. Specialists of the institution will produce the work you need much faster and better.

Remove the front wheel hub too

If you need to remove the hub of the front wheel, you should know that the wheels themselves are first removed. Next, with a swivel fist, you need to dismantle the sensor, and from the rack you should remove the lock plate. Now you can unscrew the mounting bolts from the caliper bracket.

In order for the caliper bracket, with the next operations, the entire process of working with the hub prevented, sweat it. Next, it is necessary to remove the brake disc, get a pin and weaken the lock nut. The hub itself and wheel bearing must be disconnected from the drive shaft.

Important! When performing the process of removing the hub, the drive shaft hinge cannot be exhausted, under any circumstances. We do not recommend overlooking when stretching the sliding hinge. And the drive shaft should not simply hang without support on the body and other spare parts.

After performing all the necessary requirements, we can remove from the wheel of the hub. But if a person took off the hub incorrectly, problems may be able to fix only in the service center.
