9. Pre set the carrier
bearing preload by
tightening the housing
carrier bearing race ring
nut until it requires 1.5
to 3.3 ft-lbs to rotate the
differential assembly.
NOTE: Rotate the carrier
assembly whenever
adjusting the ring nuts.
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.
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.
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.
14. Install the cover and all of the cover bolts. Torque
to 45-50 ft-lbs.
15. Check the gear lash between the ring and pinion
gears. The gear lash should be .005 to .007 inches.
16. Adjust the gear lash if needed by tightening or
loosening the carrier bearing race ring nuts. The
two ring nuts must be turned equally in opposite
directions.
NOTE: To move the ring gear closer to the pinion:
Loosen the housing carrier bearing race ring
nuts and tighten the cover carrier bearing race
ring nut equally.
NOTE: To move the ring gear away from the
pinion:
Loosen the cover carrier bearing race ring
nut and tighten the housing carrier race
ring nut equally.
17. Install the locking roll pins into the housing and
cover to lock the ring nuts in place.
18. Remove the pinion gear holding tool.
19. Install the primary reduction gear case, axles and
housings, motor, and install the complete drive
onto the vehicle.
20. Fill the drive with oil. Refer to the
Lube Chart
section for information regarding type of oil. Refer
to
Change Oil
section for information regarding
the proper oil level..
21. Lower the vehicle.
22. Reconnect the main positive and negative cables
at the batteries.
23. Remove the blocks from behind the wheels.
24. Test drive the vehicle.
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.
