LUBRICATION PROCEDURE

WARNING
Read "Spicer Life Series Driveshaft Lubrication
Warnings and Cautions"
Driveshaft's Service Manual DSSM-0100.
1. Use recommended lubricant to purge all
four seals of each universal joint. This
flushes abrasive contaminants from each
bearing assembly and assures proper filling
of all four bearings.
WARNING
Maximum grease gun pressure should not
exceed 60 psi. Excessive
pressures may cause seal damage.
2. Make sure fresh grease is evident at all
u-joint bearing seals.

If any of the seals fail to purge, try to
move the propeller shaft from side-to-side
while applying grease gun pressure.
a) If all four bearing positions still do not
purge, releasing seal tension may be
necessary.
b) Remove the bearing retainer bolts and
bearing retainers and discard. Do NOT
reuse.
c) Once the bearing cups are free, allow
the propeller shaft to rest on the support
strap.
d) Apply a c-clamp around the inboard
bearings.
Apply grease gun pressure. Completely
e)
purge both bearings.
f) If bearings still do not purge, complete
the removal of the u-joint and inspect for
blockage.

g)
positions after following the steps in this
procedure, replace the u-joint.

INSPECTION RECOMMENDATIONS

U-joint inspections should be performed
every time a vehicle comes in for scheduled
maintenance.
