.
Do not pull off bearing inner races and bearing cages that have been pressed onto the spur gears. Do not pull out bearing outer races that have been pressed into the housing.
Do not interchange the position of the spur gears or their bearings and shims, as the bearings and shims are set to each other and are run-in.
Notes:
The spur gears, bearings, housing end cover (Item
19
) or housing of the transfer gearbox (Item
9
) cannot be renewed individually, as this changes the bearing preload of the spur gears. If one of the components is damaged, the complete rear intermediate drive must be renewed.

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
