running tolerances. Gear life and gear noise are greatly
affected by these tolerances; therefore, it is very
important to properly adjust any gear set prior to final

The following procedure can be used on both front dif-
ferential or rear drive gear case.

shimming.
1. Install the existing shim or a 0.051-0.055-in. shim
on the gear case side of the ring gear assembly.
2. Install the ring gear with shim in the gear case;

ring gear forward and back to determine if any
backlash exists. If no backlash exists, install a
thicker shim and recheck.
3. Install the bearing flange onto the gear case cover
making sure the alignment/locating pin engages
the locating hole in the cover; then make sure the
bearing flange is completely seated in the cover.
4. Install the existing shim or a 0.063 in. shim on the
cover side of the ring gear; then place the assem-
bled gear case cover onto the gear case and secure
with three cap screws. Tighten evenly using a
