Do not mix spindle nuts and lockwashers from different sys-
tems. Mixing spindle nuts and lockwashers can cause
wheel separation.
Note: The lockwasher for a four-piece tang/dowel-type wheel
nut system is thinner than the lockwasher for a three-
piece tang-type wheel nut system and is not designed
to bear against the inner nut.
1. Inspect the spindle and nut threads for corrosion
and clean thoroughly or replace as required.
Note: Proper assembly and adjustment is not possible if the
spindle or nut threads are corroded.
2. Inspect the tang-type washer (if used). Replace the
washer if the tangs are broken, cracked, or damaged.
3. Install the hub and drum on the spindle with care to
prevent damage or distortion to the wheel seal.
4. Completely fill the hub cavity between the inner and
outer bearing races with the same lubricant used in
the axle sump.
5. Before installation, lubricate the outer bearing with
the same lubricant used in the axle sump.
Note: Lubricate only with clean axle lubricant of the same type
used in the axle sump. Do not pack the bearings with
grease before installation. Grease will prevent the
proper circulation of axle lubricant and may cause
wheel seal failure.
6. Install the outer bearing on the spindle.
7. Install the inner nut on the spindle. Tighten the inner
nut to 200 lbs. ft. (271 N•m) while rotating the wheel
hub.
Never use an impact wrench to adjust wheel bearings. A
torque wrench is required to assure that the nuts are prop-
erly tightened.
8. Back off the inner nut one full turn. Rotate the wheel
hub.
9. Retighten the inner nut to 50 lbs. ft. (68 N•m) while
rotating the wheel hub.
10. Back off the inner nut exactly 1/4 turn.
Note: This adjustment procedure allows the wheel to rotate
freely with 0.001"–0.005" (0.025 mm–0.127 mm)
endplay.
11. Install the correct lockwasher for the wheel nut sys-
tem being used.
Three-piece Dowel-type Lockwasher System
a. Install the Dowel-type lockwasher on the spindle.
Note: If the dowel pin and washer are not aligned, remove
washer, turn it over and reinstall. If required, loosen the
inner nut just enough for alignment.
Never tighten the inner nut for alignment. This can preload
the bearing and cause premature failure.
b. Install the outer nut on the spindle and tighten to
350 lbs. ft. (475 N•m).
c. Verify wheel endplay.
