Shimming the differential
Differential shims set the position of the carrier bearings and the gear mesh inside the housing. Small changes in shim thickness change backlash and tooth contact, so shims should be checked as a set rather than swapped one at a time. Measure the existing stack before removing anything, since it gives the starting point.
Gear life depends on correct backlash and contact pattern. After shimming, check the contact pattern with marking compound and confirm backlash for the gear set. Keep the bearings clean and lubricated during assembly, and replace any worn bearing before reuse.
- Measure the original shim stack before removing parts
- Check backlash and tooth contact after shimming
- Replace worn bearings during rebuilds
- Use fresh gear oil after the rebuild
