Determining Shim Thickness

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2010 Volkswagen Jetta, 2009 Volkswagen Jetta, 2009 Volkswagen GLI, 2008 Volkswagen Jetta, and 2008 Volkswagen GLI. However, it is still accessible from the selected car via links, so may be relevant.

The specified bearing preload is obtained by adding a constant preload figure of (0.20 mm) to the reading obtained (0.25 mm) and the thickness of the shim installed (1.70 mm).

Example:

Inserted adjusting shim	1.70 mm
- measured value	0.25 mm
+ Preload (constant value)	0.20 mm
Adjusting shim thickness	1.65 mm

-- Select the correct adjusting shim thickness according to the table. Refer to ADJUSTMENT SHIM TABLE .

-- Remove the transmission housing and remove the tapered roller bearing outer race from the transmission housing.
