Support bearing front struts: photos, symptoms. How to replace bearing-front?

Pillow block bearings are elements of the front suspension of the car. Their main task – the smoothing of the shock loads on the body. A malfunction of these items does not Bode well. In addition, the suspension and the body will wear faster, significantly worse and the car's handling. And it already carries a certain risk for the driver and passengers.

In this article we'll talk about what constitutes a Block bearings front struts how they work, what is and what is their principle of action. In addition, we consider the process of replacing these suspension components on the example of the car VAZ-2110.

Purpose

Pillow block bearings front struts today installed in all cars regardless of whether they are front-wheel drive or rear wheel drive. They are included in the design of supports with which the upper part of each of the absorbers is attached to the body.

Pillow block bearings front struts is designed to absorb the loads coming from the wheels via the strut to the body of the machine, as well as their uniform distribution. This distribution is achieved due to the special design.

How to construct a support bearing front: photo description

Structurally, pillow block bearing – normal rolling bearing. Its working elements are either steel balls or rollers, are made of the same metal. Design feature is the presence of a special separator by which each of the balls (rollers) are separated from each other and acts as a single element. This actually allows you to evenly distribute radial and thrust loads on the body.

Varieties of bearings for VAZ-2110

Pillow block bearings front struts there are four types:

• With built-in ring;
• With detachable inner ring;
• With detachable outer ring;
• Single-separated.

The First type is characterized by the presence of the special mounting holes. When you use these parts clamping flanges are used. In addition, Pillow block bearing-front VAZ-2110 with integral ring equipped with built-in pads that provide a constant and maximum rotation accuracy.

Design with detachable inner and outer rings are located the latter. In the first case, the outer ring is in contact with the device body, the second – domestic. By and large, not much difference for a car such as the VAZ-2110 these bearings are not. But the fourth type of components is characterized in that its outer ring is split at one particular point, causing rigidity of the entire device increases substantially.

Where to find pillow block bearings

Pillow block bearings located in the engine compartment of the vehicle. Open the hood of the car and note on the convexity of the body on both sides of the engine compartment. These are the places which are attached to the rack. They are also called “glasses”, and one of them is usually embossed serial number. Bearings installed on top of the “glasses” and closed with special caps round shape. They are easily disassembled by hand. Removing the cover, you will find the upper part of the bearing housing. To the body it is attached with three bolts, the nuts from which you will immediately see.

When you need a replacement main bearing

The design of the bearing is sufficiently durable that it can last for years to come. But given the quality of the coating on our roads, it often happens that they have to change almost every year.

According to the list of maintenance work for the VAZ-2110 replacement of the bearings should be carried out after every 100 thousand kilometers. Well, if you found that they failed before the deadline, don't delay the replacement. This will suffer and the chassis, and the body, and the elements of the control system.

Symptoms bearing-front

Signs of bearing failure, regardless of the design type are:

• Characteristic knock when driving on uneven surfaces;
• A sound similar to crunching while turning with the roll during the movement;
• Disruption of normal drivability.

How to diagnose the bearing fault

To know exactly what Pillow block bearings front struts are the cause of these symptoms, you will need to carry out simple diagnosis. It is desirable to invite assistant. The algorithm is as follows:

1. Place the vehicle on flat ground, Immobilise it with the Parking brake.
2. Open the hood of the car.
3. Remove the protective cover of one of the “glasses”.
4. Place your hand on “Cup” and have an assistant rock the vehicle on the same side to make the corresponding strut. If out of order Referencebearing-front fault you define the characteristic for the sound and accompanying vibration which you will feel the hand.
5. Similarly check the opposite stance.

Before how to replace bearing-front personally, make sure you have on hand the following tools and instruments:

• Jack;
• Brace;
• Wrenches on 9, 13, 19, 22;
• Special puller for steering tips;
• Tie for springs stands;
• Pliers;
• Marker, paint, or core;

2. Remove the bolts securing the front wheel from the side where you going to change the bearing.
3. Raise the vehicle, remove the bolts, remove the wheel.
4. Order after replacing the bearing you will not have to do alignment, paint or punch alignment marks on the upper bolt to the steering knuckle.
5. Using the pliers, pull the cotter pin fixing nut ball tip (of the finger). Remove the nut key 19.
6. Using a puller, mypressure finger from the knuckle of the rack.
7. The Key 19 remove the nuts on the bottom of the steering knuckle (2 PCs.) Often they are stuck, so it's best to treat them with liquid rust.
8. In the engine compartment Unscrew the three nuts fixing the upper support to the body using a key of 13.
9. With ties for springs struts unload the rack. Using the keys 9 and 22, Unscrew the nut of fastening of a support at the front.
10. Remove the prop and take it apart.
11. Remove from it the thrust bearing. Install a new part.
12. Refit the removed elements in reverse order.
13. Don't forget to check the match marks you made on the top bolt to the steering knuckle.
14. After Completing the installation, check how it works stand and doesn't that extraneous sounds. If all goes well, you can check out a new part in the movement.

How to extend the service life of bearings front struts

To bearings lasts longer, use the following tips:

3. Noticing at least one of the signs of a faulty bearing, hurry to replace it. This will prolong the service life of other suspension components and steering.
4. If you are Going to replace the thrust bearing, buy only genuine parts from famous manufacturers.
5. Periodically check the operation of the stands, listening for noises.
