8. Back-off the inner nut exactly 1/4 turn.
Note: This adjustment procedure allows the wheel to rotate freely with 0.001"-0.005" (0.025mm to 0.1 27mm) end-play.
9. Install the correct lock washer for the wheel nut system being used.
Procedure - Three piece tang-type lock washer system (see Fig. 2).
1. Install the Tang-type lock washer on the spindle.
Never tighten the inner nut for alignment. This can preload the bearing and cause premature failure.
2. Install the outer nut on the spindle and tighten to 250 lbs. ft. (339 N.M.).
3. Verify end-play (see End Play Verification Procedure)
4. After verifying end play, secure wheel nuts by bending one of the locking washer tangs over the outer wheel nut and another
tang over the inner wheel nut as shown in Figure 4. (below)
Procedure - Three piece dowel-type lock washer system (see Fig. 1)
1. 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.
Never tighten the inner nut for alignment. This can preload the bearing and cause premature failure.
