Prevention

* Nuts which need to be tightened the required moment only after installation of the car on wheels are noted.



Removal

PERFORMANCE ORDER
1. Put back sitting.
2. Remove a back cover from a wheel arch.
3. Turn out three top nuts of fastening of a back rack.
4. Remove a back wheel.
5. Disconnect a brake tube and the sensor of frequency of rotation of a wheel from a back rack.
6. Turn off nuts and get bolts of fastening of a rack to the fastener of a back axis and get a rack from under a car wing.

Prevention

Be careful not to damage a rack of a back suspension bracket.



Dismantling

PERFORMANCE ORDER
1. Special adaptation squeeze a spring of a rack of a back suspension bracket.

Prevention

For compression of a spring use only the reliable tool.


2. Turn off a lock nut in the top part of a rod of the shock-absorber.
3. Remove a rack support, the top support of a spring, a cylindrical spring, a dustproof cover and the lower support of a spring.

Check

PERFORMANCE ORDER
1. Check a rack support for lack of wear or damages.
2. Check rubber details for absence of damage or deteriorations in their state.
3. Check a cylindrical spring for lack of a deflection and loss of elasticity.
4. Check the shock-absorber as follows:

a. undertake a hand a rod of the shock-absorber and several times press and extend it from the shock-absorber;
b. check that the rod moves smoothly, without jammings, and the effort enclosed to a rod does not change with each course;
c. be convinced that when moving a rod there are no extraneous noises.

Assembly

PERFORMANCE ORDER
1. Establish the lower support of a spring so that its ledges entered plate openings of a spring.
2. Install a dustproof cover on the shock-absorber.
3. Special adaptation squeeze a spring of a rack of a forward suspension bracket. After full compression of a spring install it on the shock-absorber.
4. Completely extend a rod of the shock-absorber and establish the top support of a spring and a support of a rack.

Prevention

Combine a D-shaped opening in the top support of a spring with lysky on a shock-absorber rod.


5. Correctly arrange the top and lower ends of a cylindrical spring, having established them in dredging, and screw самоконтрящуюся a nut, but do not tighten it finally.
6. Arrange a bolt of fastening of a support of a spring so that to combine projections of laying, as shown in the drawing.
7. Remove the device for compression of a spring.
8. Tighten самоконтрящуюся a nut the required inhaling moment.

Inhaling moment: 40–55 N • m
