Fig. 1 Tools for loosening and tightening drive pinion nut
A - Socket (32 mm)

Fig. 2 Removing nut for drive pinion
- Secure retainer 3304 with two M8 x 30 hex bolts.
- Support final drive when loosening nut (e.g. using universal support
V.A.G 1359/2 in combination with transmission jack V.A.G 1383 A).

Note:
If the specified friction torque is exceeded, the spacer sleeve must be
replaced and the adjustment repeated. A spacer sleeve which has been
compressed too much cannot be reused. Fig. 11 Tightening nut for drive pinion and measuring friction
torque
- Secure retainer 3304 with two M8 x 30 hexagon bolts.
- Support final drive when tightening nut (e.g. using universal support
V.A.G 1359/2 in conjunction with transmission jack V.A.G 1383 A).
- Fit a new drive pinion nut.
- Tighten drive pinion nut just far enough so that no play can be felt at
drive pinion.
- Gradually increase tightening torque, checking friction torque at regular
intervals, until specified friction torque is obtained Fig. 12
