Disassembly and Reassembly
For procedures used in the removal and installation of Spicer
Driveshafts from the vehicle, please consult the vehicle manu-
facturer’s service manual. This manual concerns itself only
with the disassembly and reassembly of driveshaft compo-
nents.
Universal Joint
Disassembly - Snap Ring Design
Please refer to the Universal Joint information in the Compo-
nent Safety section on page 2.
With the driveshaft removed, the following procedure should
be followed:
1. Using snap ring pliers, remove the snap rings from
the yoke ears.
2. Set the yoke in the arbor press with a piece of tube
stock beneath it. Position the yoke with the universal
joint grease zerk (nipple) fitting pointing up to pre-
vent interference during disassembly. Place an
appropriate push rod on the upper bearing assembly,
and press it through to release the lower bearing
assembly.
Do not distort yoke ears with excessive force while in the
arbor press.
3. If the bearing assembly will not pull out by hand after
pressing, grip the bearing cup and pull from the
yoke.
4. Place the yoke in the arbor press with the remaining
bearing cup face down. Using an appropriate push
rod, press on the end of the journal cross trunnion.
Continue to press down on the journal cross trun-
nion until the shoulder of the journal cross makes
contact with the inside of the yoke ear.
5. Repeat steps three and four on the remaining bear-
ing assemblies to remove the cross from the yoke.
6. Inspect all yoke cross hole surfaces for damage.
Raised metal or fretting can be removed from yoke
cross holes with a fine-toothed file and/or emery
cloth.
