Withdrawal
1. Disconnect the wire "masses" from the battery. Access to the steering rack with the engine installed is very difficult, it is not easy to make it easier.
2. Release the fasteners. then remove the shelf cover at the rear of the engine compartment.
3. Remove the battery as described in chapter 5A.
4. Turn away bolts of fastening and remove the shelf of the accumulator.
5. Remove the air filter and air ducts as described in the respective credit chapter 4.
6. Remove the pads under the front panel on the driver's side to gain access to the base of the steering column.
7. Tie the top and bottom sections of the column with wire. This is necessary so that they do not fall apart when the column is removed from the steering shaft.
Warning: When removing the steering column from the steering gear, do not allow it to be separated into sections - the alignment of the internal components will be disturbed.
8. Turn away a nut of a coupling bolt of a collar of fastening of the hinge to a shaft of the steering mechanism. Turn the bolt half a turn and remove it from the clamp.
9. Pull the steering column hinge off the steering shaft and move it aside. Separate the plastic trim from the motor shield and drag it into the passenger compartment.
10. Apply the handbrake, raise the front of the vehicle and install the jack stands. Remove both front wheels. When removing the wheels, turn one bolt into the hubs so that the brake discs do not move.
11. Remove the right rotary fist, as described in p.p. 1...10 and paragraph 2 of this chapter. Take care not to damage the rubber boots of the steering tips when removing.
12. Disconnect the bottom of the right suspension strut from the lower suspension arm as described in paragraph 3, but do not loosen the top support nuts.
13. Turn away three bolts and remove an arm of fastening of the top cross-section levers, a rack of a suspension bracket and both levers one knot from the right arch. Bolts can be accessed through a shelf at the rear of the engine compartment. Plastic washers can be installed under the bolt heads. These are installation factory components that do not require re-installation after removal.
Note: Remember the location of all washers under the bolt heads, they must be installed in their places during assembly so as not to disturb the adjustment of the front wheel alignment angles.
14. Unscrew the plastic nut, unhook the latches and remove the part of the locker that closes the window into the body for the passage of the tie rod to the steering knuckle.
15. Clamp the hoses at the power steering reserve tank with clamps or clamps. This minimizes fluid loss during subsequent operations.
16. Mark for ease of assembly, unscrew the bolts connecting the tubes to the steering mechanism: be prepared for a spill of liquid - substitute suitable dishes for this. Disconnect both tubes and remove sealing washers. Discard the washers - new ones are required for installation. Plug the holes to prevent fluid from escaping and dirt from entering the system.
17. Release the tubes from the fasteners and take them away from the steering mechanism.
18. Remove the heat shield in front of the steering gear.
19. On models with air conditioning, disconnect the wiring connector from the pressure sensor on the steering gear housing.
20. Turn away bolts of fastening of the steering mechanism. Only three bolts: two on both sides of the shaft housing on the right side of the mechanism (one is accessible from the top of the case, the other from the bottom). The third bolt is located to the left of the steering gear and can be accessed from above through a shelf at the rear of the engine compartment.
21. Remember proper routing of all hoses and wiring.
22. Together with an assistant, release the steering mechanism from the engine shield and bring it out through the right arch, removing it from the car. Take care not to damage the hoses, wiring and rubber boots.
23. Having removed the steering mechanism, make sure that its covers are not damaged and, if necessary, replace them (pic. 17.23).
Pic. 17.23. Steering Gear and Components - Right Hand Drive Models: 1. Steering gear; 2. Control hole with plug; 3. Connecting bolt (hollow); 4. Connecting bolt (hollow); 5. Adjusting screw; 6. Sealing washer; 7. Return tube; 8. O-ring; 9. Feeding tube; 10. Bolt; 11. Sleeve; 12. Nut; 13. Sleeve; 14. Damper; 15. Bolt
Repair
24. Check for wear and damage to the steering gear. The rail should move freely and smoothly throughout its entire course, bases of tangible backlash and jamming. Make sure that there are no damages or leaks in the hydraulic connections of the mechanism and that the connecting bolts are securely tightened.
25. Repair of the mechanism with the replacement of damaged components is possible, but this operation is best completed by an Audi / VAG dealer. You can independently replace the covers and hinges of the steering rods. Repair procedures are described in many sections of this chapter.
Installation
26. Before installation, the rail must be centered. Unscrew the plug with an internal hexagon from the control hole on the side of the mechanism case. Move the right tie rod by hand so that the hole on the rack is visible in the control hole. Take a bolt with the same thread as the plug and sharpen it into a cone. Screw the bolt into the body so that its cone enters the rail hole. Check the fixation of the rail by pulling it by the rods. The rack is in the middle position (pic. 17.26).
27. Install the mechanism together with an assistant, trying not to damage the hoses and wiring, lay them correctly.
28. Install the two rack mounting bolts that are accessible from above, but tighten them at this stage only "by hand".
29. Install the mechanism mounting bolt accessible from below and tighten it to the prescribed torque. Tighten the top two bolts to the prescribed torques (pic. 17.29).
30. Secure the hydraulic pipes under the mechanism and tighten the connecting bolts using new o-rings on both sides of the fittings. Make sure that the tubing is installed correctly and tighten the fitting bolts to the prescribed torques. Tighten the tube mounting bolts securely. Remove clamps from hoses.
31. Operating in the car, put a plastic flexible cover on the steering shaft and secure it to the motor shield.
32. Attach a collar of the hinge of a steering column to a shaft. Insert the tie bolt, turn it half a turn counterclockwise. Screw on the nut and tighten it "by hand".
33. Remove the wire that tightens both sections of the steering column.
34. Remove the self-made bolt from the control hole in the rail housing, wrap the original plug and tighten it to the prescribed torque.
35. Tighten a bolt of a collar of the hinge of a steering column the prescribed moment.
36. Install the pads under the front panel on the driver's side.
37. Install a plastic cover inside the wheel arch, covering the window in the mudguard for the passage of the steering rod. Secure it with clamps and plastic nuts.
38. Install the bracket for mounting the upper transverse suspension arms into the arch, forgetting to put all the washers in their places. Install the three mounting bolts and tighten them to the specified torque.
39. Attach the bottom of the suspension strut to the lower wishbone as described in paragraph 3. Tighten the bolt and nut to the specified torque.
40. Install the right steering knuckle as described in p.p. 17...23 paragraph 2 of this chapter. Be careful not to damage the rubber boots.
41. Install a heat shield in front of the steering gear.
42. On A/C models, connect wiring to rail housing pressure sensor.
43. Install the wheels, lower the vehicle and tighten the wheel bolts to the prescribed torque.
44. Tighten the hub bolt to the specified torque as described in paragraph 2 of chapter 8, then install the hub cap.
45. Install the battery shelf and tighten the bolts securely. Install the battery as described in chapter 5A. Place the cover on the butt at the rear of the engine distance.
46. Install the air filter and air ducts as described in the relevant part chapter 4.
47. Add brake fluid to the reservoir as described in weekly checks and bleed the hydraulic system as described in paragraph 19.
48. Finally, check the front wheel alignment as soon as possible by contacting your dealer or an appropriate workshop for assistance.
