41−01 Driveline Inspection
1. Park the vehicle on a level surface, apply the
parking brakes, and chock the tires.
CAUTION
Due to the extreme load occurring at high−speed
rotation, a loose or broken capscrew at any point
in the driveline will weaken the driveline connec−
tion, which could eventually result in serious ve−
hicle damage. Tighten bearing−cap capscrews or
yoke−strap capscrews to specif ed torque, being
careful to not overtighten.
2. For U−joints with bearing caps,tighten bearing−
cap capscrews 43 lbf·ft (49 N·m). See . Fig. 1
For Ar vin Mer itor RPL series U−joints, tighten
bearing−capcapscrews 125 lbf·ft (169 N·m). See
Fig. 2 .
For U−joints with y ok e straps,tighten yoke−strap
capscrews 125 lbf·ft (169 N·m). See . Fig. 3
3. Check the driveline yokes for cracks, and check
end−yokes for looseness. See
. Fig. 3
Replace cracked yokes.
If any end−yoke can be moved in or out on its
shaft, or can be rocked on its shaft, disconnect
the driveshaft and U−jointfrom the yoke, then
check the drive component’s shaft seal for leak−
age or other visible damage that may have been
caused by the loose yoke. Replace the seal if
needed, then tighten the yoke nut. Refer to
Group 41 of the Casc adia TM Workshop Manual
for torque specifications. If the yoke is still loose
after tightening the yoke nut, replace the end−
yoke and yoke nut.
Replace the prevailing torque locknut (end−yoke
nut) if it was removed for yoke replacement, seal
replacement, or any other reason.
4. Check U−jointassemblies for wear by moving the
driveshaft up and down, and from side to side. If
any movement of the U−jointcross in the bear−
ings can be felt or seen, replace the U−joint as−
sembly.
5. Check if the midship bearing and mounting are
loose or have deteriorated, by attempting to
move the driveshaft up and down, and from side
to side. If the bearing is loose on its shaft, or
rattles, replace it. If the bearing mount is loose
on the frame, tighten the mounting fasteners to
the proper torque value. See
of the Group 41
Casc adia Y Workshop Manual for torque specif−
cations. Replace the midship bearing assembly if
the rubber cushion is deteriorated or oil−soaked.
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 Fig. 4
clockwise, or counterclockwise movement
