1. Using a soft drift, tap the outside of the bearing cup
assembly to loosen snap ring. Tap bearing only hard
enough to break assembly away from snap ring.
Remove snap ring from yoke. Turn joint over, tap
bearing away from snap ring, then remove opposite
snap ring.
Apply alignment marks (1) on the yokes of the
universal joint, then remove snap ring.

2. Set the yoke in the arbor press with a piece of tube
stock beneath it.
Place a solid plug on the upper bearing assembly and
press it through to release the lower bearing
assembly.

3. If the bearing assembly will not pull out by hand after
pressing, tap the base of the lug near the bearing
assembly to dislodge it.
4. To remove the opposite bearing, turn the yoke over
and straighten the spider in the open hole. Then
carefully press on the end of the spider so the
remaining bearing moves straight out of the bearing
spider hole. If the spider or bearing are cocked, the
bearing will score the walls of the spider hole and ruin
the yoke.
5. Repeat this procedure on the remaining bearing to
remove the spider from the yoke.
6. Make sure of proper position for reinstallation by
applying setting marks, then remove spider .
Inspection and Repair
Make necessary correction or parts replacement if wear,
damage, corrosion or any other abnormal condition is
found through inspection.
NOTE: When any part of the journal assembly (spider,
needle roller bearing) requires replacement, be sure to
replace the entire assembly.
Check the following parts for wear, damage, noise or any
other abnormal conditions.
1. Spider
2. Needle roller bearing
3. Yoke
4. Flange
5. Boot
Spider pin for wear
Spider pin should be smooth and free from fretting or
galling. Visible signs of needle presence is normal, but
wear should not be felt.

Propeller shaft run±out
Support the propeller shaft on V-blocks (2) and check for
run-out by holding the probe of a dial indicator (1) in
contact with the shaft.
Static run-out limit:
0.13 mm (0.005 in)
TIR on the neck of the slip tube shaft (with a
boot).
0.25 mm (0.010 in)
TIR on the ends of the tubing 3 inch from the
welds.
0.38 mm (0.015 in)
TIR at the linear center of the tube.
0.38 mm (0.015 in)
TIR for the full length of tube with 30º or less of
tubing.

Spline
The nylon-coated spline should be free from nicks and
dings and the underlying steel spline should not be visible.
After cleaning the nylon coating spline, the coating should
exhibit only slight indicator of wear.
Grease volume is approximately 10 grams of grease in
total. Grease should be evenly applied to both the female
and the male slip splines using a small brush. After
assembly of the slip joint, the sliding joint should be fully
worked from the full collapsed to the full extended
position.
Play in the universal joint
Limit: Less than 0.15 mm (0.006 in)
401RW023
Preload of the universal joint
Preload should be 0 to 49 N(0 to11.0 lb). Joints should
rotate smoothly and freely and should exhibit no rough or
ratchety movement.

Universal Joint Reassembly
1. Install spider to flange yoke. Be sure to install the
spider by aligning the setting marks made during
disassembly.
2. Pack the four grease cavities of the spider with a high
quality, extreme pressure N.L.G.I. Grade 2 grease.
Do not add additional grease to the bearing cup
assembly.
3. Move one end of the spider to cause a trunnion to
project through the spider hole beyond the outer
machined face of the yoke lug. Place a bearing over
the trunnion diameter and align it to the spider hole.
Using an arbor press, hold the trunnion in alignment
with the spider hole and place a solid plug on the
upper bearing. Press the bearing into the spider hole
enough to install a snap ring.
401RW020
4. Install a snap ring.
Be sure the snap rings are properly seated in the
grooves.
5. Repeat steps 3 and 4 to install the opposite bearing. If
the joint is stiff, strike the yoke ears with a soft
hammer to seat needle bearings.

1. Apply grease evenly to both the female and male
splines.
2. Apply a small amount of grease by finger to the outer
lips of the boot.
3. Slide the boot onto the yoke shaft being careful not to
damage the spline coating or boot.
4. Insert the yoke shaft spline into the sleeve being
careful to maintain proper phasing. The spider holes
should be in line and as per originally marked prior to
disassembly.5. Position boot onto sleeve and yoke shaft in final
position over boot grooves.
6. Attach boot clamps and secure using pliers.
7. Be sure clamp is properly seated and secure.

Removal
1. Raise the vehicle on a hoist.
NOTE: Apply alignment marks on the flange at the rear
propeller shaft both front and rear side.
2. Remove transfer side bolt, nut and washer (except
spline yoke type).
3. Remove rear axle side bolt, nut and washer.
4. Remove rear propeller shaft.
NOTE: Plug the hole of the transmission rear end to
prevent oil leakage (spline yoke type only).
Installation
NOTE: Never install the shaft assembly backwards.
Never insert bar between yoke lugs when tightening or re-
moving bolts.
Completely remove the dust or foreign matter from the
connecting surface of flange coupling on each end of the
propeller shaft.
1. Align the mark which is applied at removal.

1. Lay the shaft horizontally on a bench and secure.
2. Indicate the original assembled position by marking
the phasing of the shaft prior to disassembly.

of the boot clamp upwards and away from the
propeller shaft boot. Be careful not to damage the
boot.4. When boot clamps becomes loose, remove by hand.
