Shim Calculation
WARNING: This page is about a different car, the 2020 Chrysler 300 and 2019 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
By adding the sum of the above readings you will be able to determine the correct shim needed.
Your base line shim will be 2.047 mm, add this to the pinion depth variance/deviation (1). The variance/deviation marking on the pinion head in 0.01 mm increments. Therefore, for the shown in illustration, 0.03 mm (0.0012 in.) would be added to the shim thickness.
Add your dial indicator reading measurement for pinion height (1).
Add your gauge rod protrusion measurement (1).
The sum of the above will be the shim size needed (1).
