Maintenance
Note: The E-Z Lube feature is designed to allow immersion. If the hubs are re-
moved from the axle, it is imperative that the grease seals be replaced. A worn or
defective grease seal will allow brake lining contamination during the bearing greasing
procedure.
Seal Inspection and Replacement
Whenever the hub is removed, inspect the seal to assure that it is not nicked or torn
and is still capable of properly sealing the bearing cavity. If there is any question of its
condition, replace the seal. To replace the seal take the following steps:
1. Pry the old seal out of the hub with a screwdriver. Be careful not to scratch or nick
the sealing surface of the hub with the end of the screwdriver.
2. Clean the hub surfaces. If the bearing is removed for any reason, be sure to
reinstall it before pressing in the new seal. Apply a Permatex sealant to the outside of
the new seal (metal seal shells only).
3. Tap the seal into place using a clean wood block.
Hub Reinstallation and Bearing Adjustment
1. Place the hub (with inner bearing set and grease seal installed), outer bearing,
spindle washer and spindle nut back on the spindle in the reverse order of removal.
Rotate the hub assembly while tightening the spindle nut to approximately 50 lbs.-ft. of
torque.
2. Then loosen the spindle nut to remove the torque. Do not rotate the hub.
3. Finger tighten the spindle nut until just snug.
4. Install a new cotter pin (tang washer for E-Z lube hubs). If necessary, the nut can
be backed off slightly to align the castellations with the cotter pin hole in the spindle.
Bend over the tangs of the pin.
5. Check that the hub turns freely and is without unusual sounds. The spindle nut
should be free to move until restrained by the cotter pin or tang washer.
