Check Universal Joint Capscrews
DANGER
Inspect RPL Series Permalube and Wing-Style Permalube
drivelines for loose or missing capscrews and lock washers.
Loose or missing fasteners can allow the driveline to separate
from the vehicle. Serious personal injury and damage to
components can result. If fasteners are loose or missing:
• RPL Series Permalube drivelines: Install new capscrews with
Dri-Loc patches.
• Wing-Style Permalube drivelines: Install new capscrews with
Dri-Loc patches and secure the capscrews with lock washers.
Meritor recommends that you inspect RPL Series Permalube
bearing cup capscrews and wing-style capscrews and lock
washers at initial inspection, or no more than 2,000 miles
(3200 km).
On RPL Series Permalube Drivelines
1.
Check that capscrews are installed on all universal joint
positions. RPL Series Permalube capscrews and Wing-Style
Permalube capscrews are not interchangeable.

DOWN and SIDE-TO-SIDE motion. Figure 4.14 and Figure 4.15.
There should be less than 0.006-inch (0.152 mm) BACK-AND-
FORTH motion of the universal joint. Figure 4.16 and Figure 4.17.
