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. 6 , item 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 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. 6 . 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.
