1. Remove needle retaining plugs from all
bearing cup assemblies. Using a high quality
National Lubricating Grease Institute E. P.
Grade 2 lubricating grease, wipe each
bearing cup assembly with grease. Fill all
cavities between the needle rollers. Also
apply a liberal coating of grease on the
bottom of each bearing cup assembly and
on the lip of the seal.

2. Position the journal cross into the yoke cross
holes with the grease zerk fitting inward
toward tubing. The double-headed, grease
zerk (nipple) fitting should be perpendicular
to the yoke cross holes.
Note: Failure to properly position the
universal joint will result in the inability to
grease the universal joint.

Note: Always inspect bearing cups for rollers
that may have fallen (downed rollers) out of
place before installation.

a trunnion to project through the cross hole
beyond the outer machined face of the yoke
ear. Take one bearing cup assembly and
position an installation height tool on the end
of the bearing cup assembly. Place the
bearing cup assembly over the protruding
trunnion diameter and align it to the yoke
cross.
