Installation
1. Using driver handle J–8092 and input seal installer
J-44905, install input seal in drive gear retainer. Place the
new primary seal on the installer with the seamed side of
the stainless steel perimeter facing toward the drive gear
retainer. Drive the seal in until the installer bottoms against
the drive gear retainer. The seal will be recessed in the
drive gear retainer approximately 0.310". This dimension
is critical and must be achieved using the special tool.
(Figure 9-21).
2. Secure shim gasket(s) and drive gear retainer to geared
hub with washers and bolts (Figure 9-20).
3. Secure vent line bracket and speed sensor bracket to drive
gear retainer with washers and bolts. Tighten all four bolts
to 38 lb-ft (52 N•m).
4. Coat lip of input seal with gear oil (Figure 9-21).
5. Stretch the v-seal over the seal area of the halfshaft with
the thick side against the c-v joint. Lubricate the thin side
of the v-seal with an all purpose grease. This portion of the
v-seal will contact the stainless steel portion of the
primary seal when the halfshaft is installed.
