2. inspect the indle and nut threads for corrosion and ean thoroughly or replace as required.
Note:
Proper assembly and adjustment is not possible if the spindle or nut threads are corroded.
●
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.
* CAUTION: A wheel dolly is recommended during installation to make sure that the wheel seal is not damaged
by the weight of the hub and drum. Never support the hub on the spindle with just the inner bearing and seal.
This can damage the seal and cause premature failure.
●
Completely fill the hub cavity between the inner and outer bearing races with the same lubricant used in the axle sump.
4. 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 bearing with
grease before installation. Grease will prevent the proper circulation of axle lubricant and may cause wheel seal failure.

●
Install the outer bearing on the spindle.
●
Install the inner nut on the spindle.
●
Tighten the inner nut to 200 lbs. ft. (271 N. M.) while rotating the wheel hub.

THREE PIECE TANG-TYPE LOCK WASHER SYSTEM (see Fig. 2).
*Install the Tang-type lock washer on the spindle.
IMPORTANT: Never tighten the inner nut for alignment. This can preload the bearing and cause premature failure.
*Install the outer nut on the spindle and tighten to 250 lbs. ft. (339 N.M.).
*Verify end-play (see End Play Verification Procedure)
*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)
THREE PIECE DOWEL-TYPE LOCK WASHER SYSTEM (see Fig.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.
IMPORTANT: Never tighten the inner nut for alignment. This can preload the bearing and cause premature failure.
*Install the outer nut on the spindle and tighten to 350 lbs. ft. (475 N.M.).
*Verify end-play (see End Play Verification Procedure)
