Determining shim thickness
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 1995 Volkswagen Jetta III, 1995 Volkswagen Golf III, 1995 Volkswagen Cabrio, 1994 Volkswagen Jetta III, and 1994 Volkswagen Golf III. However, it is still accessible from the selected car via links, so may be relevant.
The specified bearing preload is achieved if the reading (example: 0.93 mm), the specified bearing preload (0.12 mm) and the amount allowed for compression (0.10 mm) are deducted from the 2 x 1.5 mm thick shims.
Determining Shim Thickness Example: Drive Pinion Bearing Preload
| Shims installed (2 x 1.5 mm) | 3.00 mm |
| - Dial indicator reading | - 0.93 mm |
| - Preload | - 0.12 mm |
| - Amount for compression | - 0.10 mm |
| = Thickness of shim | 1.85 mm |
- Remove output gear. Determine correct shim size from table. See TABLE OF SHIMS FOR DRIVE PINION AND INPUT GEAR . Install shim on drive pinion.
- Re-install output gear, tighten hex nut, and secure with drift.
