Diagnostics of malfunctions of a back suspension bracket

Suspension bracket of spring type

Noise in a suspension bracket take place
The shock-absorber and/or its basic knots is faulty. Check a condition of rubber plugs of shock-absorbers (see an accompanying illustration). Replace defective components.

Bearings of naves of back wheels are damaged, or their adjustment is broken. Modify a pretightness, or replace defective bearings.

Nuts or plugs of a back spring earring are worn-out, or weakened effort of a tightening of fixture. Replace defective components, tighten fixture.

The anchor finger or the plug are worn-out, or landing weakened them. Replace defective components, tighten fixture.

It is broken one or more sheets of a spring. Replace defective sheets, or entirely a spring.

The bridge case is deformed. Replace a case.

The spring collar is broken, or weakened its fastening. Tighten fixture, or replace a defective collar.

The spring step-ladder is broken, or weakened its fastening. Tighten fixture, or replace defective step-ladders.

For an assessment of degree of wear of plugs of an earring and an anchor finger of a spring get the lever between a spring and chassis loop and move them a spring up-down. Thus the weight of the car should fall on a suspension bracket.
Visually examine spring sheets on existence of cracks and other damages.
In view of high capacity of springs of a suspension bracket it is inexpedient to check a condition of shock-absorbers of a suspension bracket on the car. Shock-absorbers should be removed and checked according to the description provided further in this Section.

The provision of back wheels of the car in relation to lobbies is broken
Weakened bolts of step-ladders of lobbies or back springs of the car. Check the central bolt, tighten U-shaped bolts of step-ladders (see an accompanying illustration).

The central bolt of a lobby or back spring is broken. Replace a bolt.

The main leaf of a lobby or back spring behind a basic plate is broken. Replace the main leaf or a spring assembled.

The anchor finger or forward earring of a spring is broken. Replace defective components.

Strong sagging of a spring from one of car boards takes place. Replace springs from both boards.

The bridge case is deformed. Replace a case.

For correctness check an arrangement of the forward bridge measure distance from a reference (reperny) point on a bridge case to a reference (reperny) point on the chassis. Repeat measurement between equivalent reference (reperny) points from other board of the car. Results of measurements should coincide.

Course stability of the car is broken

Too poorly or tires are pumped non-uniformly up. Modify pressure of a rating of tires.

Serviceability of functioning of the shock-absorber of a suspension bracket is broken. Check, replace the defective block (preferably together with the second shock-absorber of this suspension bracket).
Plugs or nuts of an earring of a spring are worn-out, or weakened effort of a tightening of the last (see an accompanying illustration). Tighten fixture, or replace defective components.

Lobbies or back springs are worn-out or broken. Replace a defective spring together with opposite the same suspension bracket (forward or back).

In view of high capacity of springs of a suspension bracket it is inexpedient to check a condition of shock-absorbers of a suspension bracket on the car. Shock-absorbers should be removed and checked according to the description provided further in this Section.
If the back of the car is tilted in one or other party, remove the corresponding spring and compare it to the new. If the spring is found unsuitable for further use, it will be reasonable to replace it together with opposite. The same concerns a car front.

Suspension bracket on screw springs

Noise in a suspension bracket take place
The shock-absorber and/or its support is faulty. Check, examine rubber pillows of support of shock-absorbers on existence of signs of aging (see an accompanying illustration). Replace defective components.

Bearings of naves of back wheels are damaged, or their adjustment is broken. Modify a pretightness, or replace defective bearings.

Weakened bolts or nuts of plugs of a suspension bracket. Give the corresponding fixture completely, then tighten it with demanded effort by means of a dinamometrichesky key.

Plugs or bolts of pushing bars of a suspension bracket are worn-out. Remove components for check of their condition. In case of need make replacement.

Support of the stabilizer of cross-section stability or spherical support are worn-out, or weakened their fastening.

The screw spring is broken. Replace a spring together with the second.

Bearings of assembly of a rotary fist are faulty. Check, execute the corresponding repair or replacement.

The bridge case is deformed. Replace a case.

For an assessment of degree of wear of plugs of a cross-section jet bar ask the assistant to rotate a steering wheel to the left-to the right within a course of 30 cm from the center in each of the parties. Excessive люфт plugs will testify to their wear. The car weight during this check should fall on wheels.
Plugs of shock-absorbers can be checked by a way of slow rocking of a front of the car in the vertical plane (again resort to the help of the assistant). Let's allow only very insignificant люфт in plugs.

The provision of forward wheels of the car in relation to the back is broken
Plugs of pushing bars of a suspension bracket are worn-out, or weakened their fastening. Check (see an accompanying illustration), tighten fixture, or replace defective components.

Pushing bars or their reference points are damaged or deformed. Compare dimensional characteristics of pushing bars to obviously serviceable detail.

Strongly the screw spring from one of car boards gave. Replace springs in pair.

The bridge case is deformed. Replace a case.

For correctness check an arrangement of the forward bridge measure distance from a reference (reperny) point on a bridge case to a reference (reperny) point on the chassis. Repeat measurement between equivalent reference (reperny) points from other board of the car. Results of measurements should coincide.

Course stability of the car is broken

Too poorly or tires are pumped non-uniformly up. Modify pressure of a rating of tires.

Serviceability of functioning of the shock-absorber of a suspension bracket is broken. Check, replace the defective block (preferably together with the second shock-absorber of this suspension bracket).
Plugs of a cross-section jet bar are worn-out, or weakened their fastening. Replace plugs, or tighten fixture (see an accompanying illustration).

Plugs of pushing bars of a suspension bracket are worn-out, or weakened their fastening. Replace plugs, or tighten fixture.

The lobby or back screw spring is broken or gave. Replace a spring together with the second the same suspension bracket (forward or back respectively).

If the front falls from one board more strongly than from another, remove the corresponding screw spring and compare its characteristics to the new. If the spring is found not suitable for further use, replace it together with the second. The same concerns also springs of a back of the car.
