6.0 STEERABLE DRIVE END
ASSEMBLY
6.1 GENERAL PRECAUTIONS FOR
ASSEMBLY
1. Assembly
Refer to the exploded views located in the parts
section as an aid to assembly.
2. Initial Lubrication
Splines and grease seal lips should be coated
and filled with grease prior to reassembly to pro-
vide lubrication upon start up.
3. Bearings
Use of flanged-end bearing drivers is recom-
mended for the installation of bearings and
races. These drivers only apply force to the
races of the bearing, preventing damage and
maintaining alignment with the shaft and bore.
4. Seals
Use a flanged type guide or driver to install
seals. If a driver is not available, use of a soft
hammer and/or wood blocks may be made, pro-
vided that care is exercised. Proprietary drivers
are available directly from Fabco and drawings
are also provided in Section 10.0
6.2 SPINDLE INSTALLATION
1. If the inner axle seal has been removed, smear
grease on the inner bushing surface of the re-
placement part and apply a thin bead of Loctite
gasket eliminator to the outer surface. Drive it
into the suspension yoke until it seats squarely
against the shoulder of the bore.
CAUTION THE BRONZE INNER BUSHING
SURFACE HAS AN OIL PASSAGE
WHICH SHOULD BE LOCATED
AT 3 OR 9 O'CLOCK BEFORE
THE SEAL IS DRIVEN IN.
2. Place the lower kingpin plate in the suspension
yoke and drive in the bearing and seal after it.
See
Figure 18
. Both upper and lower kingpin
seals must be installed in their bores w/grease
lips facing outward. If the upper kingpin bearing
has been removed, install the new part using ei-
ther a pusher plate or the old part as a driver.
See
Figure 19
. If necessary, install a new upper
kingpin seal against its shoulder opposite the
upper kingpin bearing.
3. If necessary, install a new wheel end inner seal.
See
Figure 20
. Grease lightly all seal lips and
kingpin bearings.
4. Reinstall the drive axle shaft assemblies being
careful not to score the inner axle seal.
