Removal and installation of an amortization rack and case of the wheel bearing

GENERAL INFORMATION

Amortization rack and case of the wheel bearing

1–a nut with a fillet, 60 N • m. Being self-stopped, it is necessary to replace surely.
2–cup
3–amortization rack. For replacement of a spring or the shock-absorber it acts in film and established completely.
4–the screw with an internal shestigrannik, 8 N • m
5–ABS sensor
6–nut, 45 N • m. Being self-stopped, it is necessary to replace surely.
7–spherical support
8–case of the wheel bearing
9–cover
10-bolt, 7 N • m
11-wheel bearing
12-lock ring
Take out together with the help of usual nippers. At installation watch the correct situation.
13-nave. With a rotor for the ABS sensor
14-bolt. Surely replace.
15-nut, 50 N • m + 90 ° (1/4 turns). Being self-stopped, it is necessary to replace surely.

REMOVAL

PERFORMANCE ORDER
1. Remove a wheel cap. At wheels from easy alloys the cap acts in film by means of demountable hooks from a set of the onboard tool.
2. Unscrew a dvenadtsatigranny nut of fastening of a shaft of a drive to a nave.
ATTENTION

At a bolt otvorachivaniye the car should stand on wheels. There is a danger of accident owing to the big moment of an otvorachivaniye!


3. Mark paint the provision of the corresponding forward wheel concerning a nave. It will allow to establish at assembly an otbalansirovanny wheel in its former situation. Weaken bolts of fastening of a wheel at the car standing on the earth. Lift a forward part of the car, put it on supports and remove a forward wheel.
ATTENTION

Operation of lifting and car installation on supports is connected with danger! Therefore before carrying out operation familiarize with car Poddomkrachivaniye's subsection.


4. Mark a felt-tip pen or a chertilka the provision of bolts of fastening – 1–spherical support. Otherwise at assembly it is necessary to measure a forward suspension bracket and to adjust it. Turn out bolts – 1–.
5. Disconnect by means of a stripper a drive shaft from a nave.
ATTENTION

Do not disconnect a brake hose from a brake support. Otherwise after assembly it is necessary to remove systems from system air.


6. Depending on model various options of a design of a forward brake can be established. FS-III support: Remove covers – 2–and disconnect a support. A casing of a support suspend on a wire to the chassis. FN-3 support: Unscrew bolts with edges from a support casing. At installation it is necessary to replace them with the new. Remove a support, address to the subsection Removal and installation of a brake disk/support.
7. Unscrew the screw with a crosswise shliyets and remove a brake disk.
8. Unscrew a nut of fastening of the hinge of steering draft till the end of a carving. It carries out a support role for a stripper.
9. Wring out a stripper (And), for example, Hazet 779 a pin of the hinge of steering draft from the lever.
10. Disconnect the tip – 1–sensors of number of turns of ABS.
11. Remove an ABS sensor wire from the holder (shooter).
12. Unscrew a nut of fastening of an amortization rack the AUDI 3186 tool, holding thus a screw-driver under an internal shestigrannik of 7 mm for a rod from a provorachivaniye. If the specified tool available is not present, unscrew a nut by means of a cranked cap key. There is a special Hazet No. 2593-21 tool.
13. Take out an amortization rack and the case of the bearing of a wheel down through a wheel casing.
14. Separate the case of the bearing of a wheel and an amortization rack. For this purpose unscrew a bolt of fastening of an amortization rack to the case of the bearing of a wheel.
15. Take out an amortization rack up from the case of the bearing of a wheel. If it is hardly taken out, for simplification of dismantle expand shlitsa in the case of the bearing of a wheel with the AUDI tool – 3424 or any other suitable tool a little.
INSTALLATION
16. Put on the case of the bearing of a wheel an amortization rack so that openings at a pipe of the shock-absorber and the case of the bearing coincided.
17. Insert into the bearing case / an amortization rack a new bolt. The bolt head at the established amortization rack is ahead in the movement direction. Screw a new being self-stopped nut and tighten it the moment of 50 N • m, then a rigid key tighten on 90 ° (1/4 turns).
18. Before installation of an amortization rack grease a rack support with assembly G 294 421 F1 oil (shooters on an illustration).
19. Insert an amortization rack and fix from above a new nut the moment of 60 N • m, keeping her from a provorachivaniye a key under an internal shestigrannik of 7 mm.
ATTENTION

To establish a dinamometrichesky key, as the tool it is possible to apply AUDI – 3186 or HAZET 2593-21 complete with 2100-07 to deduction from a provorachivaniye.


20. Clear teeths and a carving of a shaft of a drive and a nave a brush of corrosion and other pollution.
21. Cover a dvenadtsatigranny nut and teeths of the external hinge on a drive shaft with pure impellent oil. Enter as it is possible more deeply the external hinge in nave teeths.
