Assembly of Front Differential
1. Be sure that all parts are clean and free of any dirt or
debris. Make sure that all residual oil has been removed
from differential components.
2. Carefully install new square sectioned O−ring into
the groove in the cover plate.
IMPORTANT: When installing output hub assembly
into cover plate, be careful to not damage the seal
in the cover plate. The seal cannot be serviced sepa-
rately.
NOTE: The output hub that is installed in the cover plate
has an extended bushing.
3. Press the new output hub/bearing assembly into the
cover plate assembly. The bearing has a slight interfer-
ence fit to the bore, so it should not take much force to
install (Fig. 21). Take care to not damage the seal in the
cover plate during installation of the hub assembly.
4. Set the armature plate onto the coil located in the
cover plate (Fig. 22). The internal tangs of the armature
plate should face up as shown.
5. Place the gear spacer on top of the armature plate
and secure with retaining ring (Fig. 23). Make sure that
retaining ring is fully seated into groove in cover plate.
