Installation

Universal Joint
WARNING
Use a brass or synthetic mallet for assembly and disassembly
procedures. NEVER hit steel parts with a steel hammer. Pieces
of a part can break off. Serious personal injury and damage to
components can result.
CAUTION
Do not seat the bearing cups into the yoke saddle by tightening
down the bearing straps and capscrews. Uneven load
distribution, yoke bearing rotation, and damage to the straps and
yoke nibs can result.
NOTE: To help ensure maximum driveline performance, do not
apply lubricant, grease, anti-seize compound, etc., to the yoke
saddles.
1. Install the universal joint cross into the yoke. Always use new
bolts and straps.
NOTE: For easier installation, do not remove the wire that fastens
the bearing cups to the universal joint trunnion.
2. Install the bearing cups through the yoke bores and onto the
universal joint cross trunnions.
3. Tap the bearing cup lightly with a leather or rubber mallet to
seat the bearing cups into the yoke saddle.
NOTE: Capscrews have a "lock patch" and can be hand-tightened
only two or three threads.
4. Hand-tighten the bearing capscrews. Use a torque wrench
to tighten the capscrews to the specifi ed torque. Refer to
Table D.
Driveline
1. Wipe off the yoke saddle.
NOTE: Any time a universal joint is disconnected, new capscrews

capscrews onto the slip yoke end of the driveline.
NOTE: Capscrews have a "lock patch" and can be hand-tightened
only two or three threads.
3. Hand-tighten the capscrews through the bearing strap into the
yoke.
