(SERIAL NUMBERS 300000 AND ABOVE)
This task covers:
a. Removal
b.
Installation
NOTE
Replacement procedures for right and left rear differential output
shaft seals are basically the same. This procedure covers the right
side output shaft seals.
1.
Remove locknut (3), O-ring (4), and output flange (5) from output shaft (8). Discard O-ring (4) and
locknut (3).
2.
Remove two capscrews (2) and brake adapter (1) from differential (9).
3.
Remove output shaft seal (7) from differential (9).
1.
Using axle shaft and seal installer (6), install output shaft seal (7) on differential (9).
CAUTION
Apply a liberal amount of thread sealing compound to the tapped
holes of differential. To allow adequate coating of threads, install
capscrews shortly after applying thread sealing compound. Failure
to do this could allow capscrews to loosen and cause damage to
differential.
2.
Apply sealing compound to tapped holes of differential (9) and install brake adapter (1) on
differential (9) with two capscrews (2). Tighten capscrews (2) to 125–150 lb-ft (170–203 N
•
m).
3.
Install output flange (5), O-ring (4), and locknut (3) on output shaft (8). Tighten locknut (3) to
170 lb-ft (231 N
