Rear Axle Oil Seal

[icecoldtexan]

I just replaced my rear axle oil seals in my '01 2500HD 4x4. When I pulled the wheel hub off par tof the old seal stayed on the shaft. I pulled that part off and pulled out the part still in the hub. I then pressed the complete new seal in the hub then pressed the hub/seal assembly on the differential. then tightened the retaining nut and replaced the spring clip to prevent the nut from coming loose.

I couldn't take the seal apart to place one piece on the diff and the other piece in the hub. Did I do the job correctly ? Also if I ever take the hub off will the seal split in two again ? It doesn't leak and seems to be file, just want to know if this was the correct technique.

Thanks.

Yes the seal will split in half again and it will need to be replaced.

 

Here is the procedure on adjusting the hub bearing.

 

Tighten the wheel bearing adjusting nut using the J 2222-C .

Rotate the hub in the opposite direction to the way the adjuster nut is turning.

Ensure the inner bearing and the seal seats against the spindle shoulder.

Tighten the adjusting nut to 70 N·m (52 lb ft).

Turn the adjusting nut counterclockwise until the nut is loose using the J 2222-C .

Turn the adjusting nut clockwise until the nut contacts the bearing cone. Torque on the nut must be zero to finger tight.

 

Insert the adjusting nut lock key into the keyway using one of the following procedures:

• If the adjusting nut slot is in alignment with the keyway in the axle spindle, insert the adjusting nut lock key into the keyway in the axle spindle.

 

Important: Do not turn the adjusting nut more than one slot counterclockwise in order to align the adjusting nut slot with the keyway in the axle spindle.

 

• If the adjusting nut slot is not aligned with the keyway in the axle spindle, turn the adjusting nut counterclockwise until the adjusting nut slot is in alignment with the keyway in the axle spindle and insert the adjusting nut lock key.
