Differential, assembly: Notes
WARNING: This page is about a different car, the 1999 Volkswagen GTI, 1998 Volkswagen GTI, 1997 Volkswagen GTI, 1996 Volkswagen GTI, and 1995 Volkswagen GTI. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- Heat inner race of tapered roller bearing to 100°C (212°F) before installing.
- Always replace both tapered roller bearings together, as a set.
- When replacing the differential housing, transmission housing, or tapered roller bearings, also adjust the differential, see Differential, adjusting .
