Output shaft bearing wear
The inner bearing on the rear output shaft supports the shaft as it turns inside the transfer case, and it carries load from the gears and chain. A worn bearing can cause a whine that changes with speed, play in the output shaft, or oil leaking past the seal behind it. Left alone, the bearing can damage the gear it supports.
Bearing replacement goes hand in hand with a check of the output shaft, the seals and the case bore for wear or scoring. Clean all parts thoroughly and lubricate the bearing as the service procedure for your transfer case calls for. Because the work is internal, plan for the transfer case to be removed or opened, and allow extra time for reassembly and shimming.
- Whine that rises and falls with speed
- Play or wobble in the rear output shaft
- Oil leaking past the rear seal
- Rough feel when turning the shaft by hand
