REMOVAL OF DIFFERENTIAL
CARRIERS FROM AXLE HOUSINGS

10. Separate differential carrier from the housing using

removal slots.

See Figures 1 and 2. Be certaindif-

ferential carrier clears dowel pins and is balanced
properly on jack. Remove top two carrier mounting
bolts, and remove differential carrier assembly from
the axle housing.

NOTE: Steam clean axle assembly.
1. Block wheels.
2. Remove axle housing and power divider drain plugs

and drain lubricant.

3. Disconnect drive shaft at the rear U-joint.
NOTE: If end yoke and/or seal is to be replaced,
loosen yoke nut at this time.
4. Match mark each axle shaft flange to its mating

wheel end and remove axle shaft flange nuts.

IMPORTANT: Axle shafts are of different lengths and
should be marked accordingly for proper reassembly.
5. Hold a large brass drift or a brass hammer against

the center of the axle shaft flange. Strike the drift
with sharp blows from a large hammer or sledge
until the axle shaft separates from the hub.

CAUTION: Do not strike the flange directly with
a steel hammer or sledge. This may crack and
splinter material, possibly causing serious or fatal
injury. Do not pry or chisel axle flange away from hub
or damage to sealing surfaces could occur.
6. Remove axle shafts. Remember due to different

length axle shafts, each shaft should be marked
to mating wheel end for proper reassembly.

7. Disconnect air line from power divider shift cover on

forward rear assembly.

8. Support the differential carrier assembly on a roller

jack. Secure as necessary to prevent it from
falling off the jack when removed from the housing.

9. Loosen the differential carrier-to-housing

mounting bolts. Remove all bolts except top two.
These two bolts will prevent the carrier assembly
from falling.

IMPORTANT: Thread two guide pins into axle housing
to relieve weight from output shaft bearing assembly
of forward rear during differential carrier removal.
