Power Train Disassembly & Assembly
Adjust the wheel Bearing
Preload
NOTE : To adjust the wheel bearing preload, the
bearings must be seated and the rollers in proper
alignment.
Use a brass or leather mallet for assembly and
disassembly procedures. Do not hit steel parts
with a steel hammer. Pieces of a part can break off
and cause serious personal injury.
1. Install the wheel bearing adjusting nut (16).
Tighten the nut 400 lb•ft (542 N•m).
2. Rotate the hub (24) in both directions. At the same
time, rap the hub several times with a brass or
plastic mallet.
3. Tighten the nut to 400 lb•ft (542 N•m) again.
4. Back off the nut approximately 1/4 turn to relieve
the preload produced in Step 3.
5. Tighten the nut to 200 lb•ft (271 N•m).
NOTE : If you move the adjusting nut to align the
lock plate mounting holes, advance or tighten the
nut. Do not loosen or back off the nut.
6. Install the lock plate (19) to either a nut flat or nut
corner.
Take care when using Loctite to avoid serious
personal injury. Follow the manufacturer’s
instructions to prevent irritation to the eyes and
skin. If Loctite gets into your eyes, flush them with
water for 15 minutes. Have your eyes checked by
a doctor as soon as possible.
7. Install the lock plate mounting screw (18). Tighten
the mounting screws to 20-30 lb•ft (27-41 N•m).
a. New lock plate mounting screw threads come
equipped with a pre-applied locking agent.
b. If the original lock plate mounting screws (18)
are used, apply two or three drops of Loctite
277 or equivalent to the internal threads of the
ring gear hub (20).
8. Apply axle grease to the inner face of the sun gear
thrust washer (15) to help retain the washer to the
nut.
9. Install the sun gear thrust washer (15) so that the
washer tangs must engage the slots in the bearing
adjusting nut (16).
10. Install the planetary sun gear (14) and snap ring
(13) onto the axle shaft (33).
11. Install the axle shaft and sun gear assembly (33,
14, 13).
•
The axle shaft must engage the differential side
gear.
•
The sun gear must make contact with the thrust
washer (14).
•
The thrust washer tangs must be properly engaged
in the ring gear hub holes.
