grease is seen at the seal, then tighten the cap-
screws to the correct torque specifications. If the
bearing will not take grease, replace the U-joint.
See

Workshop Manual for replacement instructions.
6. Check the purged grease. If it appears rusty,
gritty, or burned, replace the U-joint.
7. Wipe the purged grease from the seals, and any
excess grease from the grease fitting.
Slip Joint Spline Lubrication
NOTE: Vehicles equipped with Meritor RPL Se-
ries drivelines do not require periodic lubrication.
1. If equipped with a grease fitting, wipe all old
grease and dirt from the slip joint grease fitting.
See
Fig. 5 , Ref. 1.
2. Use a hand-type grease gun or a high-pressure
gun with a low-pressure adapter, to lubricate the
slip joint. Add multipurpose chassis grease
(lithium 12-hydroxy stearate, NLGI Grade 1 or
Grade 2, with EP additives) until it appears at the
pressure-relief hole in the yoke plug. Then cover
the relief hole with your finger, while continuing
to apply gun pressure until new grease appears
at the slip joint seal. See
Fig. 5 . This ensures
complete lubrication of the splines.
3. Wipe the purged grease from the pressure-relief
hole and slip joint seal, and any excess grease
from the grease fitting.
