screws to the correct torque specifications. If the
bearing will not take grease, replace the U-joint.
Refer to Group 41 of the vehicle 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.
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 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.
