The comfort and quality of movement depends on the state of the rear and front suspension, as well as the safety of passengers and the driver. The key function of each suspension is mitigating driving and eliminating oscillations. But, in addition, the running part performs a number of important functions, namely: ensuring a smooth stroke, a decrease in rolls during turns, the provision of sufficiently high informativeness for the motorist on high-speed highway and in the city. To avoid problems associated with the suspension, it is necessary to systematically check it. But to determine the wear of silent blocks or suspension levers, it is absolutely not necessary to resort to the help of specialists - to check the condition of the suspension of the vehicle and on its own. About this further in the article.

VAZ suspension, from which the suspension consists, from which the life of the suspension elements depends

The service life of the pendant components is greatly different in different countries, and the quality of the road canvase.

If the suspension changes abroad rather rarely, then with our roads you have to change the suspension elements several times a year. Probably everyone saw a car that fell in the direction of the front wheel. This occurs as a result of late replacement of the lower ball support or front suspension levers. And well, if the speed was small at the same time.

The front suspension of the car VAZ consists of:

Wheel hub bearings (1), hub cap (2), adjusting nut (3) washer (4), rotary fist pin (5), wheel hub (6), gland (7), brake disc (8), ball finger Supports (9), swivel fist (10), case for the protection of the ball finger (11), the bearing of the upper support (12), the upper suspension lever (13), the body of the upper support bearing (14), the compression buffer (15), bracket For compression buffer (16), the support glass of the shock absorber (17), cushions of the shock absorber (18), pillow pillows (19), insulating spring gasket (20), the supporting upper cup of the spring (21), the top lever axis (22), Internal hinge sleeve (23), outer sleeve hinge (24), rubber hinge sleeve (25), support washer (26), adjusting washers (27), remote washer (28), bracket, with which the spar is attached to the crossbar ( 29), crossing the front suspension (30), fastening bracket bar stabilizer (31), stabilizer rod pillow (32), stabilizer rod (33), lo KUZNA RCZON (34), axis of the lower lever (35), lower suspension lever (36), fastening bolts of lower lever axis (37), suspension spring (38), fastening rod stabilizer (39), shock absorber (40), fastening bolt Stabilizer (41), Nut, with which the shock absorber bracket is attached to the suspension lever (42), the bracket by which the shock absorber is attached to the lower lever (43), the supporting lower cup of the spring (44), the bottom support liner (45), Bearing Bearing Bearing Bearing (46), Ball Figure Coupler (47), Lower Support Bearing (48), Ball Finger (49), Wheel Turn Limiter (50).

Shrusa boot, bushings and silent blocks, how to determine in what state they are

Covers (not rarely called anthers) are intended to protect the responsible vehicle components from premature wear (for example, shruses). When diagnosing the chassis, the car must carefully examine the lateral of the hinges covers. Rubber sleeves in the components of the suspension are quenched by strong road blows, not allowing them to get to the body, and, at the same time, they act as hinges, providing mobility of suspension elements.

To diagnose the condition of covers, you need to feel their hands. If the finger shifted to the edge of the center of the faces, then the rubber bushing is broken or very worn. To determine the wear of the silent blocks (rubberometallic joints) of the suspension levers, it is necessary to act with a passage or by assembly to displace the lever relative to the body. The presence of a backlash or knock will indicate the wear of silent blocks. Look, there is no cracks on the protruding edges of the suspension levers, rubber sleeves and face shock absorbers.

The boot of a VAZ scraper when it should be changed, in what cases are changing the rubber bushings and silent blocks

Torn anthers entail a lot of other troubles, since dust and dirt accumulates in them, which in time falls into the node itself. When replacing the node, it is necessary to immediately change the boot - if you do not replace the torn boot immediately, the node quickly fails. If there are cracks on the covers that are speaking the edges of the faces of shock absorbers, suspension levers or rubber sleeves, it is necessary to replace them. If the rubber sleeve broke or worn out, it should also be replaced with a new one. As for silent blocks, they must be changed with their wear (in the presence of a knock or a backlash).

Sometimes the rear suspension rods have a tubercle, protruding the inside of the eye, which is able to quickly wipe the new rubber sleeves. This tubercle needs to run or replace the bar.

Suspension cracks, in what cases can be used welding, and when it is only necessary to replace the part to the new

All nodes and parts that are strongly loaded with vibrations and blows suffer from fatigue and cracks appear on them. For example, the levers of the front suspension VAZ are more likely to be cracked near the silent blocks, under the supports of the springs, as well as near the ball supports. If the cracking of the transverse thrust takes place as a result of the cracks (in the middle, where it is closed by protection, or at the edges, near the fastener bolts of the lower lever axis), then it should be replaced with a new one - to welding in this case it is prohibited.

As for the front suspension, in this case, it is possible to brew cracks in this case, but it is advisable to "back up" the place of repair, imposing patches. In addition, you can take advantage of welding if the bracket of the transverse rod broke on the VAZ.

Auto wheel crack, can you move on such wheels

Wheels of the vehicle cracked either do not bypass the party. Plastic Steel Wheels Over time, it is easy to crack near the ventilation windows or bolt holes. Ride on a cracked wheel is already dangerous. Even more attention is required fragile wheels with light alloy. After any impact, they must be carefully examined.

Shock absorbers and springs of VAZ suspension, how to find out in what state they are when you can repair, and when only replacement is needed

The behavior of the car changes greatly if the state of the springs and shock absorbers of the suspension is not important. When the vehicle comes out from the conveyor, the characteristics of all components of the suspension are carefully chosen - the shock absorbers are quite effective, and the springs are elastic. In reality, the springs are capable of breaking and lose elasticity, and when their condition is very running, they break and crack. As for the shock absorbers, then as a result of the loss of fluid, they cease to extinguish oscillations.

It is impossible to repair the requested springs, so they are changed to new ones. If the shock absorbers are collapsible, they can still be repaired, otherwise - also replacement. You can check the shock absorbers by alternately rolling of all vehicle angles. If the elements of the shock absorbers are good - they will not allow more than one and a half free swing, the defective will remind the swing.

VAZ suspension hinges, how to check the condition of the hinges of the VAZ suspension

The backlash is not only the source of the knocks, but also the key to the further accelerated wear of the suspension elements, so you should not bring everything to the deplorable state. Checking the status of steering hinges is made with an assistant - one of them shake the steering wheel, the second - proves each connection.

Swivel fist hinges on VAZ are checked differently. One presses the brake pedal, the second - shakes the wheel in the vertical plane. If there are stuffs, get ready for replacement. It will not be possible to check the state of the lower hinge if it is loaded with a spring force. It must be unloaded by submitting a support for the lower lever of the suspension. Next, shaking the wheel, look, is there no backlash in the bottom hinge.

To check the hinge on the actual wear, turn away from the bottom of the hinge threaded plug, after which it is necessary to measure the distance from the spherical head of the finger to the bottom side of the don. Norm - no more than 11.8 millimeters.

On transport with the Mac-Fersson suspension (for example, on VAZ 2110) to check the state of the swivel fist, it is necessary to squeeze the wheel. When the hinge is unloaded, with the help of a lomik, pressed the lever from the hub. If tapping, it means it's time to change.

Bearings of VAZ suspension, how to check their condition.

To check the status of the bearings, it is necessary to hang the wheel and not strongly swing it. If there is a backlash in the bearings, it will immediately be noticeable.

On which models VAZ are allowing the backlash of the bearing, and on what no and why

On front-wheel drive machines with double-row ball bearings should not be a backlash. A small backlash is allowed on the VAZ with roller conical bearings, especially on the old car. If you remove it using tightening the adjusting nut it does not work, then the bearing is strongly worn out and it should be replaced.

What will happen if you turn the bearing when replacing

When replacing bearings, you should not delay them too much. If you are dragging, the hub on the move will be very hot.

Profi advice, if the details were replaced on the front suspension, why it is necessary to perform the collapse

After repair and replacing the suspension items, it is mandatory to perform the collapse, which will improve the following indicators:

1. Car handling.
2. Car stability.
3. Fuel economy.
4. Reduced tire wear.
5. Reducing car drifts.
