3. Reinstall the drain plug.
4. Remove the fill plug on the axle cap and add oil to the line on the cap. Reinstall
the plug and check for leaks.
Use a gear oil of API GL-5 performance level. SAE 90 weight oil is normally pre-
ferred for most operating environments. Other approved oil weights are SAE 80W-90,
SAE 80W-85W-90, and SAE 75W-90.
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:
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
The objective of this procedure is to attain 0.001" to 0.010" end play.
1. Place the hub (with inner bearing set and oil seal installed), outer bearing and
adjusting nut (inner spindle nut) back on the spindle in the reverse order of removal.
Rotate the hub assembly in both directions while tightening the adjusting nut to ap-
proximately 100 lbs.-ft. of torque.
2. Loosen nut to remove preload torque without rotating hub.
3. Hand tighten nut then back off
