Replace both tapered roller bearings together. If
possible, use same manufacturer!
Do not grease new tapered roller bearings
additionally for friction torque measurement.
The bearings are already greased with a
special oil from the factory.

Note:
If the specified friction torque is surpassed, replace spacer sleeve and
repeat adjustment! Any spacer sleeve that has been pressed together too
far one time must be replaced. Fig. 11 Tightening drive pinion nut and adjusting friction torque
- Install 3304 retainer using two hex bolts M8 x 30.
- When tightening nut, support final drive (e.g. using VAG1359/2
universal mount with VAG1383A transmission hoist).
- Always replace drive pinion nut.
- Tighten nut for drive pinion until no more drive pinion backlash is
present.
- Tighten further until specified friction torque is attained; while tightening
measure friction torque multiple times Fig. 12
