• Four piece Tang/Dowel type wheel nut system - Fig.3
Do not mix spindle nuts and lock washers from different systems. Mixing spindle nuts and lock washers can cause wheel
separation.
Note: The lock washer for a four piece-dowel-type wheel system is thinner than the lock washer for a three piece tang-type
wheel nut system and is not designed to bear against the inner nut.
2. 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.
• lnspect 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.
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.
5. 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.
Never use an impact wrench to adjust wheel bearings. A torque wrench is required to assure that the nuts are property
