Lubrication Procedures
Lubrication Procedures
*Spicer bolts are specially heat-treated.
DO NOT substitute with inferior grade bolts.
7. It may be necessary to unseat bearing cup assem-
blies by tapping on yoke or bearing cup with a soft-
faced hammer. Once the bearing cup assemblies are
free, allow the driveshaft to rest on support strap.
8. Apply a c-clamp around the outboard bearings.
Apply grease gun pressure. Completely purge both
inboard bearings.
9. If bearings fail to purge, slightly loosen c-clamp and
reapply grease gun pressure until both outboard
bearings purge.
10. After all four bearings purge fresh grease, retighten
c-clamp to squeeze out excess grease and wipe
clean. This will ease installation of universal joint kit
back into yoke. Install universal joint kit in the yoke
using new bearing retainer bolts, and torque bolts to
the required specifications.
11. If the bearings still will not purge, complete replace-
ment of the universal joint kit is required. See
removal section of this manual for proper proce-
dures on removing Spicer Quick Disconnect™ style
driveshaft assemblies and spring tab style universal
joints.
Slip Joint Lubrication
Lubrication Procedure for Relubale Slip Members
1. Apply grease gun pressure to the lube fitting until
lubricant appears at the seal. Always use an E.P.,
Grade 2 specification, N.G.L.I grease on spline mem-
bers. Spicer recommends the same lubricant used
for universal joints.
Caution - In cold temperatures, be sure to activate
the slip member by driving the vehicle sufficiently to
cause displacement of the grease prior to its stiffen-
ing. Failure to do so could cause the excess lubri-
cant to stiffen in the cold weather and force the
welch plug out. The end of the spline would then be
open to collect contaminants and can result in drive-
line failure.
