- 3 - distance ring (plastic)
- 4 - disc spring. Large ∅ (concave side) adheres to the retaining ring.
- 5 - collar. Be sure to replace.
- 6 - protective cover. For 90 mm hinge. Before installation, lift the small collar of the protective cover and fill the cover with air.
- 7 - clamp
- 8 - left shaft. With Tripod internal swivel. If damaged, the inner joint and shaft must be replaced.
- 9 - screw with internal teeth, 45 Nm
- 10 - right hinge. With tripode swivel. If damaged, the inner joint and shaft must be replaced.
Warning: After loosening the hex nut (axle nut), which the drive shaft is attached to the hub, do not put the car with a full load on the wheels and move it. If there is no axial preload, the wheel bearing may be damaged. If necessary, install an external joint instead of the drive shaft and secure it with a torque of 50 Nm.
Withdrawal
1. Remove the wheel trim; for light metal wheels, remove the caps with removable hooks from the on-board tool kit.
2. Loosen the hex nut of the wheel hub at the drive shaft without unscrewing it.
Warning: When loosening the nut securing the drive shaft, the vehicle should, if possible, be with its wheels on the ground. If the vehicle is raised, position the key so that the turning force acts vertically downwards. Otherwise, the vehicle may slide off the sides of the stands. Big turning point. Danger of accident!
3. Mark with paint the position of the corresponding front wheel relative to the hub. This will allow the assembly to install the balanced wheel in its original position. Loosen the wheel bolts with the vehicle on the ground. Raise the front of the car, put it on stands and remove the front wheel.
Warning: The operation of lifting and placing the vehicle on stands is dangerous! Therefore, before carrying out the operation, read the subsection car jacking.
4. Mark the position of the bolts -1- of the ball joint with a felt-tip pen or circle them with a scriber. Otherwise, it will be necessary to measure and adjust the front suspension during subsequent installation. Turn out bolts -1-.
5. If the drive shaft cannot be manually removed from the hub, remove the drive shaft with a puller. AUDI service stations use the AUDI-3283 puller for this.
Warning: Do not let the shaft hang, otherwise the inner joint may be damaged by kinking.
6. Loosen the Allen screws for the drive shaft on the gearbox flange. This requires an insert for an internal polyhedron, for example, HAZET 990 Lg-8.
7. Cars with manual transmission: Tilt the shock strut outward and remove the drive shaft from the wheel bearing housing.
Vehicles with AT:
8. Loosen the mounting bolts (arrows in the illustration) AT supports to the beam of the unit.
9. Insert a pry bar between the unit beam and the cylinder block and move the block in the direction of travel. At the same time, the driveshaft tripode joint can be pulled out.
Installation
10. Brush the teeth and threads of the drive shaft and hub to remove rust and other contaminants.
11. Attach the shaft to the gearbox. Tighten the screws with the internal polyhedron crosswise. Gearbox tightening torque (constant-velocity joint): 40 Nm; AT (Tripode hinge): 45 Nm.
12. Lubricate the mating surface of the hex nut and outer joint teeth with clean engine oil. Insert the outer joint into the teeth of the hub as far as possible.
13. Attach the ball joint to the arm. Install the mounting bolts in the oval holes so that the previously marked markings match. Tighten the bolts to a torque of 20 Nm, then tighten with a hard wrench at an angle of 90° (1/4 turn).
Warning: When installing into a new arm, center the mounting bolts and tighten. Finally, measure the camber, refer to subsection Front wheel alignment.
14. Install the drive shaft inner joint and tighten the Allen screws.
Tightening torques:
- M8 - 40 Nm
- M10 - 80 Nm
15. Vehicles with AT: Tighten the bolts securing the gearbox support to the unit beam to a torque of 25 Nm.
16. Insert the outer joint into the wheel bearing as far as it will go.
17. Tighten the hex nut to 300 Nm and then loosen it again by ½ turn.
18. Tighten the hex nut to 50 Nm, then tighten with a hard wrench by 45° (1/4 turn).
Warning: To tighten to a specific angle, HAZET 6690 angle washer is required. If this washer is not available, the hex nut can be tightened as follows.
19. Lower the car so that the wheels touch the ground.
20. Tighten the dodecagonal nut to 300 Nm and loosen it again by ½ turn.
21. Tighten the hex nut to 50 Nm.
22. Mark one face of the nut (arrow A in the illustration). Second marking (arrow B) apply to the edge of the hub through the next edge. Note: The distance from one edge to the other is 45°.
23. Tighten the hex nut with a wrench so that both markings match.
