Power Divider Disassembly - Forward Carrier Assembly
Use these instructions with the carrier assembly in or out of
the vehicle.
1. Disconnect the main driveline.
2. Disconnect the lockout airline.
3. Drain the axle lubricant into a clean oil pan.
4. Remove the input yoke nut and yoke.
5. To de-stake the nut, use a chisel or drift with a round
tip. The flange of the nut must be pushed far enough
outward so that the staked area will not interfere with
the input shaft threads when the nut is removed. See
diagrams below.
Failure to de-stake the pinion nut will result in damage to
the drive pinion threads when removed. The pinion nut
should never be reused, always replace with new.
6. Remove the input seal.
Note: Do not reuse the seals after disassembly.
7. Remove the power divider cover assembly. Use the
tabs provided to free the cover from the carrier
assembly.
During removal of the power divider cover, the inter-axle
differential (IAD), in put shaft assembly or IAD shift system
may fall from the carrier if not careful. Use caution to pre-
vent injury or damage.
8. For High Entry Applications Only:
Remove the input shaft and gear assembly. Proceed
to step 13.
9. Remove the input shaft, sliding clutch, shift fork and
spring as an assembly.
