Rear Output Shaft Seal and Bushing Installation

Tip:

Ensure both sealing surfaces of the front and rear
case halves are free of dirt, oil, and cleaning
solvent.

Apply a 2 mm (0.078 in) bead of sealant to the
front case half.

Apply the proper amount of sealant to the flange when
assembling the transfer case. Excessive amounts of
sealant can plug the oil pump screen, resulting in internal
component failure.

assembly.

Insert a rubber coated screwdriver into the speed
sensor hole and lift up on the reluctor wheel to
engage the retaining ring with the rear bearing
assembly.
