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.
9. Install the outer bearing on the spindle.
10. Install the inner nut on the spindle. Tighten the inner
nut to 200 lb-ft. (271 N•m) while rotating the wheel
hub.
CAUTION:

Never use an impact wrench to adjust wheel bearings. A
torque wrench is required to assure that the nuts are prop-
erly tightened.
11. Back off the inner nut one full turn. Rotate the wheel
hub.
12. Retighten the inner nut to 50 lb-ft. (68 N•m) while
rotating the wheel hub.
13. 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.
14. Install the correct lock washer for the wheel nut sys-
tem being used.
Three-piece Dowel-type Lock Washer System
a. Install the Dowel-type lock washer 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.
CAUTION:

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 lb-ft. (475 N•m).
c. Verify endplay.
Three-piece Tang-type Lock Washer System
a. Install the Tang-type lock washer on the spindle.
CAUTION:

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 
250 lb-ft. (339 N•m).
c. Verify endplay.
d. After verifying endplay, secure wheel nuts by

bending one of the locking washer tangs over

the outer wheel nut and another tang over the

inner wheel nut.
