4. The height of the pin is adjusted by a set screw
that is accessible from the outside of the hous-
ing. See Figure 3.42.
4a. Tightening the set screw reduces the
clearance between the ring and pinion
gears, reducing back-lash.
4b. Loosening the set screw increases the
clearance between the ring and pinion
gears, increasing the amount of back-
lash.
NOTE: Adjustment is not likely to be necessary
in the normal service life of the vehicle.
5. The pinion cover can be easily removed from the
differential assembly. See Figure 3.43.

6. The pinion shaft and bearing slip out of the hous-
ing once the cover is removed. See Figure 3.44.
NOTE: The pinion shaft can be removed
together with the pinion cover, or separately.
7. Outside of warranty, if the pinion seal develops a
leak, it can be pressed-out of the cover and
replaced with one that is locally purchased.
See Figure 3.45.
NOTE: A square section O-ring seals the pinion
cover to the housing.
