Maintenance
Bearing Lubrication
Wheel end lubricant should be replaced periodically as described earlier in this sec-
tion. Follow these guidelines for lubricant replacement:
1. If possible, wash down the area around the wheel end thoroughly.
1. Place a clean container under the axle cap.
2. Loosen and remove the oil drain plug. Allow the old lubricant to drain out completely.
Examine this oil for particles or contamination that might warrant further component exami-
nation.
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 preferred
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.
