10. Mark the position of each carrier bearing ring nut in relation to
the drive housing and cover and then remove the differential
assembly, do not allow the ring nuts to rotate.
11. Install the pinion gear. Re-shim if required.
12. Install the pinion gear holding tool (96-500-42) and tighten
the pinion nut enough to keep the pinion gear from rotating.
13. Install the differential assembly.

If the ring and pinion gears or bearings are
replaced then the pinion gear must be re-
shimmed. Improper pinion gear shims will
result in drive noise and premature failure.
Refer to Pinion Gear Shimming Instructions.
Loosen the housing carrier bearing race ring
nuts and tighten the cover carrier bearing race
ring nut equally.
Loosen the cover carrier bearing race ring nut and tighten the
housing carrier race ring nut equally.
The two ring nuts must be turned the same amount in opposite
directions. This allows the carrier assembly to be positioned with the
proper gear lash without upsetting the bearing preload. If the ring
nuts are not turned the same amount, then the bearing preload will no
longer be correct and will result in drive noise and premature failure.
