PLANETARY DIFFERENTIAL
ASSEMBLY
Refer to Figure 15, next page.
NOTE: Brake Assembly, and optional
Return to Neutral have to be removed be-
fore the following steps can be per-
formed.
DISASSEMBLY
1. Remove the axle hub assembly (118) on con-
trol side by removing nuts (119), and hub as-
semblies (118).
2. Remove the eight torx head screws (80) that
secure the R.H. housing assembly (2).
3. Remove R.H. housing assembly (2), while
holding axle shaft (76) in place.
4. Remove the two housing pins (117).
5. Remove washer (71) from axle shaft (76).
6. Remove spur gear (60), and thrust plate (62).
7. Remove 21T sun gear (61), and sleeve bear-
ing (96).
8. Remove the planetary gears (59).
9. Remove washer (70), and axle shaft (76).
10.Remove the four carrier pins (58) from plan-
etary carrier (64).
11. Remove 51T ring gear (63) from main hous-
ing (1).
12.Remove the two miter gears (66), and differ-
ential shaft (67).
13.Remove planetary carrier (64) and differen-
tial thrust plate (68).
14.If necessary, remove the second axle shaft
assembly (76) from main housing (1).
15.Remove the seal from the shaft, if necessary.
INSPECTION
1. Inspect all gears for excessive wear or dam-
age and replace if necessary.
2. Remove all sealant from both housings and
inspect seal lands for damage when clean-
ing.
3. If miter gear (65) needs replaced, remove jam
nut (73) from axle shaft (76).
ASSEMBLY
1. If necessary, install L.H. Axle shaft assembly
(76) into main housing (1). If necessary, re-
assemble axle shaft assembly (76) by install-
ing washer (70), miter gear (65), and jam nut
(73) onto axle shaft (76).
2. Install differential thrust plate (68) into main
housing (1).
3. Install planetary carrier (64) into main hous-
ing (1).
4. Reassemble the two miter gears (66) onto
differential shaft (67), and install assembly into
planetary carrier (64).
5. Install 51T ring gear (63) into main housing
(1).
6. Install the four carrier pins (58) into planetary
carrier (64).
7. If necessary, reassemble axle shaft assem-
bly (76) by installing washer (70), miter gear
(65), and jam nut (73) onto axle shaft (76).
8. Install R.H. Axle shaft assembly (76) partway
into assembled differential components.
NOTE: It will be necessary to support the
RH axle shaft in the partially installed
position while steps 9 through 16 are
completed.
9. Assemble sleeve bearing (96) and sun gear
(61), sliding them onto R.H. axle shaft. The
smaller diameter on the sun gear OD should
be “IN”.
10.Install the four 15T planetary gears (59) on
pins (80) . Make sure the planetary gears are
properly aligned with the sun gear. Mate the
bevel gear on the end of the RH axle shaft
with the bevel gears in the differential assem-
bly. Continue to support the RH axle shaft.
