Repair of a back suspension bracket
Back suspension bracket of wheels at all-wheel drive models
|

Shooters designated four fixing bolts of an amortization rack (also at all-wheel drive models). |
Removal of a back amortization rack
Front-wheel models

|
- To raise the car from both parties.
- To provide car fixing.
- To remove a wheel.
- To bring a support under an axis from that party from which the amortization rack will act in film, and thus to raise an axis approximately on 10 mm.
- To weaken the bottom fixing bolt on an amortization rack.
- To weaken four top fixing bolts on an amortization rack. Thus to hold a rack.
- To remove an amortization rack.
- At installation at first to tighten the top bolts of an amortization rack (55 N • м).
- Freely to put the bottom fastening of an amortization rack, thus to replace самоконтрящуюся a nut.
- To lower the car on the earth all four wheels.
- Only now to tighten the bottom fixing bolt of an amortization rack the moment of 240 N • m. Rezino-metal plugs otherwise can warp.

- To raise the car.
- To provide fixing of the raised car.
- To remove a wheel.
- To bring a support under the cross-section lever of a suspension bracket from that party from which the amortization rack will act in film.
- To unscrew the bottom fixing bolt on an amortization rack.
- To weaken four top fixing bolts on an amortization rack. Thus to hold a rack in order that all suspension bracket of the back bridge did not hit from within about a wing.
- To weaken and remove a fixing bolt of the cross-section lever of a suspension bracket at the top of an amortization rack.
- To remove an amortization rack.
- At installation freely to put the bottom fastening of an amortization rack, thus to replace самоконтрящуюся a nut and bolts.
- To tighten the top bolts of an amortization rack (55 N • м).
- Freely to screw a fixing bolt of the top cross-section lever of a suspension bracket, here too to replace bolts and самоконтрящиеся nuts.
- To lower the car on the earth all four wheels. If to tighten bolts of a suspension bracket of wheels on the raised car, rezino-metal plugs will warp.
- Only now to tighten the bottom fixing nut of an amortization rack the moment of 90 N • m and in summary to turn on 1/2 turns (90 °).
- To tighten a nut of a fixing bolt of the top cross-section lever of a suspension bracket the moment of 70 N • m and in summary to turn on 1/2 turns (180 °).

Removal of back shock-absorbers
Front-wheel models
Before replacement of shock-absorbers it is necessary to establish, what running gear is established on your car. Only in this case you can order the necessary shock-absorbers. It can be learned on the carrier of parameters of the car – the plate pasted in a niche of a spare wheel under a rug. Marking means:
- 1BA – serial execution
- 1BE – sports option
- 1BB – execution for bad roads
Now it is possible to begin:
|
|
- To remove an amortization rack.
- To establish a natyazhitel of springs on rounds of springs and a few to compress a spring.
- In order that natyazhitel of springs did not come off, it is necessary to paste over the corresponding rounds of springs with a kleyushchy tape.
- To remove the top rubber support of an amortization rack.
- To weaken top самоконтрящуюся a nut on a shock-absorber rod. Thus to hold it with a natural an internal shestigrannik.
- To hold the shock-absorber and to remove it after nut removal.
- To remove springs and other details from the shock-absorber.
- At assembly to pay attention:
- The bottom end of a spring at the correct installation is directed on the left side of the car back, and on right forward.
- Color marking on a spring specifies the direction down to a plate of a spring.
- The fastening opening below on the shock-absorber shows perpendicularly to the movement direction.
- Assembly of elements should be made in an order specified in drawing below.
- Installation of an amortization rack is described in the previous section.

Removal of the back shock-absorber
All-wheel drive models
At all-wheel drive cars (Audi 80 quattro) the shock-absorber separates from the removed amortization rack by means of a natyazhitel of springs. It is easy to execute it.
It becomes heavier at installation: the corner of the bottom fastening of the shock-absorber to the top fastening of the shock-absorber should make in the established condition precisely 21 ± 2 °. Without an adjusting template V. A. G. 1752 which Audi workshop uses, it is almost impossible to establish so precisely. Our council that who does not want to transfer all work in a workshop: it is possible to remove simply an amortization rack, to ask a workshop to establish precisely the shock-absorber, and then again to establish houses an amortization rack.
Regulation of bearings of naves of back wheels
Front-wheel models
|
|
- To raise a back part of the car and to fix it.
- To remove a wheel cap, шплинт and a koronchaty cap on a way described in head Brake system.
- Models with back drum-type brake mechanisms: to wring out up an adjusting wedge in the way, described in the above-stated section. Then the brake drum will rotate absolutely freely.
- Without excessive efforts to tighten a six-sided nut, rotating thus a wheel in order that did not clamp bearings.
- Again slightly to weaken a nut.
- Люфт it is established correctly if in easy pressing of a screw-driver it is possible to shift slightly a persistent washer behind a nut. The screw-driver edge thus is impossible опирать about edge of a nave of a wheel.

Bearings of a nave of a wheel of all-wheel drive models
|
|
At correctly established люфте the nave bearing in easy pressing of a screw-driver it is possible to shift slightly a persistent washer (1) under an adjusting nut (2). Thus the edge of a screw-driver should not lean on a brake drum or a brake disk. |
- If now still it is impossible to insert lock шплинт into a lock clamp, that, means, the nut needs to be turned a little in the close direction.
- To put on a wheel cap, podstukivy a rubber hammer, if necessary to enclose a hard parcel of rags.
All-wheel drive models and on a back axis have pressed double ball-bearings. Though they also do not need to be regulated, but in the absence of compression molds they cannot be changed independently.
