Remove a forward wheel.

Edge of a flat screw-driver remove a dustproof cap.

Unscrew a lock nut in the top part of a rod of the shock-absorber. Remove a rack support, the top support of a spring, a cylindrical spring, a dustproof cover and the bottom support of a spring.

Check rubber details on absence of damages or deterioration of their condition. Check a cylindrical spring on lack of a deflection and elasticity loss.
1) Check and adjust pressure in tires.
2) Load the car cargo which usually in it is transported.
3) For check of a spring make a control trip, then step by step execute the following checks.
4) Check each shock-absorber, consistently strongly pressing and lifting on the corner of the bumper closest to the checked shock-absorber. At each check make identical efforts and note resistance by pressing and return to an initial condition. Compare results of check to the car, which quality of movement the satisfactory. Both shock-absorbers on one axis of the car should show identical resistance. If resistance variously execute the following checks.
5) Lift a back axis of the car so to unload suspension bracket racks.
6) Turn out bolts of the bottom fastening of racks. Compress racks with various speed on all course of the shock-absorber and in both directions. Compare results for two parties of the car at compression and return to an initial condition. Resistance of return of a rack in an initial condition usually stronger than compression (approximately from one to two times). The right and left racks should show identical results. A difference of results between lobbies and back racks – the normal phenomenon.

1) Check the moments of an inhaling of carving connections of fastening of a rack. The inappropriate moments of an inhaling can lead to emergence of extraneous noise.
2) If all fastenings as it should be, for isolation of damaged unit execute check according to item 3 and 4).
3) For check make a control trip.
4) If one of racks of a back suspension bracket works with blows, lift a back axis of the car so to unload suspension bracket racks. Turn out bolts of the bottom fastening of racks. Check a rack on abnormal noise for what quickly and completely compress it. If hissing noise is audible only is a normal phenomenon.
5) Other undesirable noise can be found by deliberate rocking of the car up and down. Any sound except hissing is abnormal, therefore it is necessary to replace such rack.

Check the shock-absorber on leak existence.
1) Completely stretch the shock-absorber, at the same time turning a rod of the shock-absorber and check area about rod consolidation.
2) Check existence of leakages of liquid in a zone of consolidation of a rod.
3) The insignificant raid of liquid does not serve as the reason for shock-absorber replacement as insignificant leak provides rod greasing.
4) Considerable leakage of liquid from the shock-absorber can be easily found in the wake of liquid, thus it is necessary to replace the shock-absorber.

Completely extend a shock-absorber rod.

Establish on the shock-absorber a dustproof cover. The special J38402 adaptation, – 42 compress a spring of a rack of a forward suspension bracket. After complete compression of a spring establish it on the shock-absorber.

Remove the adaptation for spring compression. Tighten самоконтрящуюся a nut the demanded moment of an inhaling. Inhaling moment: 50–70 N • m. Grease the top bearing of an amortization rack and establish a dustproof cap.

At installation of a rack of a forward suspension bracket be convinced that interfaced surfaces and an identification label previously cleared is directed to a back part of the car. Tighten all carving connections by the demanded moments.

Inhaling moment:

Nut of fastening of the top part of a rack: 45–60 N • m
Nut of fastening of a rotary fist to a rack: 130–150 N • m

Fix on a rack a brake hose and an ABS sensor wire.
