The positive value is deeper than the ring gear shaft end face.

CAUTION:

• Never reuse the oil seal.

• When installing, never incline oil seal.

• Apply multi-purpose grease onto oil seal lips, and transfer oil onto the circumference of the oil seal.

Select ring gear bearing adjusting shim (transfer case side) and ring gear bearing adjusting shim (transfer cover side). Refer to Adjustment.

Assemble the selected ring gear bearing adjusting shim (transfer case side) and ring gear bearing outer race (transfer case side) to transfer case. Refer to Disassembly and Assembly.
