12.2.2. Repair of a rack of a forward suspension bracket


Prevention

For removal and dismantling of a rack of a forward suspension bracket it is necessary to use a stripper of spherical hinges and the device for compression of springs.


PERFORMANCE ORDER
1. Remove a rack of a forward suspension bracket and remove a nave, the bearing of a wheel and a protective board of a brake disk from a rack of a forward suspension bracket.
2. Fix a rack of a forward suspension bracket in a vice with soft sponges and, using special adaptation, squeeze a spring so that it departed from the top part. When using special device for compression of springs you watch that rounds of a spring were reliably taken, you make compression of a spring from the opposite sides. The spring has very big effort of compression therefore use only very reliable tool. Do not connect a spring by a wire at all.
3. Record a key a shock-absorber rod from a provorachivaniye and, using the second cap key, unscrew the central nut of fastening of a rod of the shock-absorber.
4. Remove the top support of a rack and the bearing.
5. Remove the spring support directing the plug, a shock-absorbing ring, the protection cover and a spring. On later models also remove a rubber shock-absorbing ring.
6. From the top part of a telescopic rack unscrew a ring nut and remove the shock-absorber.
7. Because the nut is strongly tightened, turn a rack and clamp a nut in a vice with soft sponges and, having inserted a bolt into the lever of steering draft, mount unscrew a rack from a ring nut.
8. Take the shock-absorber from a rack.
9. Check the shock-absorber for signs of leak of depreciation liquid. Check on all length a shock-absorber rod for lack of pointed corrosion. Check the shock-absorber case for lack of mechanical damages.
10. Install the shock-absorber in vertical position and check its work, moving a shock-absorber rod at full capacity. The rod of the shock-absorber has to move smoothly, with a notable resistance.
11. If the rod of the shock-absorber moves with breakthroughs or there are mechanically damages, the shock-absorber is subject to replacement.
12. Install the shock-absorber in a rack and fix it by a ring nut.
13. Fix a rack in a vice with soft sponges and tighten a ring nut the required moment.
14. Establish a rubber shock-absorbing ring and a cylindrical spring so that its lower end correctly settled down in the lower nest of a spring.
15. Grease the bearing of the top fastening of a rack of a forward suspension bracket with GM 19 41 574 lubricant. The bearing is an integral part of the top support of a rack of a forward suspension bracket.
16. Establish the top fastening of a rack on a piston rod, at the same time check that the lower persistent washer is established by the lifted edge up (And – the lower persistent washer, In – the top persistent washer).
17. Screw a nut on a rod of the shock-absorber and tighten it the required moment. At the same time hold a shock-absorber rod from a provorachivaniye the second wrench.
18. Slowly weaken the tool for compression of a spring. Check that extreme rounds of a spring correctly settled down in spring support.
19. Install a rack of a forward suspension bracket on the car.
