Wheel Bearings
Carefully remove the wheel hub’s dust cap with a chisel and hammer. This will expose the castle nut.
Remove cotter pin, then remove castle nut. DO NOT reuse cotter pin, always use a new cotter pin for
re-assembly.
Gently spin the hub to help you remove the drum assembly. Take note of orientation of seals,
washers and bearings. If the hub is stuck you may need to use a mallet to tap the back side of the
hub in a few spots. If the bearing is frozen to the spindle, you will need to knock off the hub with
some force. If this happens, you may have to work off the frozen bearing by using a chisel to break it
loose. Take care to not damage the spindle. If the spindle has any damage , replace spindle.
Remove outer bearing, then remove inner bearing by placing hub on a piece of wood, use a 1”
wooden dowel that will fit into the center of the hub. Use a mallet to knock inner bearing out of hub,
do this in a circular motion. The inner seal will be pushed out at the same time.
Inspect bearings, seals , race and spindle. Look for any nicks or discoloration. Replace if necessary.
Remove all old grease from bearings before re-packing bearings.
Replace parts in the same order in which your removed them. Apply a small amount of grease to the
castle nut. Final Castle Nut Adjustment:
To make sure the hub is seated properly, back off the castle nut until it is loose. Then tighten the
castle nut snugly until it stops. Look to see where the cotter pin hole lines up with one of the
notches on the nut. On hubs that use the tang washer or cage to lock the nut, you will have to do this
by sight. Then back the nut off one notch, so that the cotter pin will fit through the castle nut.
Install the cotter pin and then spin and rock the hub. When you rock the hub you should feel the
hub barely moving front to back. Try experimenting by loosening the castle nut one more notch to
feel the difference in the play in the hub. Then install the wheel and rock the hub again. On the
outside edge of the tire, the movement should not be more than 1/4" inch. Any play should be
barely noticeable. When you are satisfied with the adjustment, secure the cotter pin. Push the pin
through the hole on the end of the spindle and through the notches on the nut. Then split the
bottom of the pin to the left and right.
Re-install dust cover using a mallet. If using a bearing buddy or bearing protector unit, follow
manufactures instructions.
