6.
Check slip joints for spline wear by moving the
sleeve-yoke and splined shaft back and forth;
see
. If the slip joint can be twisted in a
clockwise, or counterclockwise movement
greater than 0.007 inch (0.18 mm), replace both
the sleeve-yoke and the splined shaft.
7.
Examine the driveshaft tubes for dents, bends,
twists, or other damage. If any tube appears to
be damaged, refer to
Section 41.00
of the
122SD and Coronado Workshop Manual
for re-
pair and replacement instructions.
8.
Examine the driveshaft for evidence of missing
balance weights, and for build-up of foreign ma-
terial. Remove any foreign material. If there is
any evidence that balance weights are missing,
remove the driveshaft and have it balanced.
9.
For driveshafts with slip joints, check to be sure
the yoke plug is not loose or missing; see
Ref. 2. Repair or replace the yoke plug as
needed. If the yoke plug is missing, the splined
shaft may be hitting the plug and knocking it out;
contact your Regional Service Office for assis-
tance in determining the correct driveshaft
length.
41–02 Driveline Lubrication
Universal Joint Lubrication
NOTE: Vehicles equipped with Meritor RPL Se-
ries drivelines do not require periodic lubrication.
1.
Park the vehicle on a level surface, apply the
parking brakes, and chock the tires.
2.
Wipe all old grease and dirt from each U-joint
grease fitting. See
3.
Use a hand-type grease gun, or a high-pressure
gun with a low-pressure adapter, to lubricate
U-joints. If a low-pressure adapter is not used,
U-joints may not receive enough grease.
Using lithium 12-Hydroxy stearate grease (NLGI
Grade 2, with EP additives), lubricate until
new
grease can be seen at
all four
U-joint seals.
Fresh grease must be seen escaping from
all
