1. 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 coat-
ing of grease on the bottom of each bearing cup
assembly and on the lip of the seal.
Note: Refer to Dana information bulletin J3295 for additional
grease specification guidelines.
Caution: Failure to use Dana recommended grease specifica-
tions may cause premature component wear and void war-
ranty coverage.
Do not add grease to non-greasable U-joint kits. Mixing
grease types and/or over greasing can cause premature
failures.
Caution - Spicer DOES NOT recommend wiping the outside of
bearing cup assemblies or yoke cross holes with grease, oil or
silicone-based sprays. This could result in bearing cup
assembly rotation in yokes.
2. Position the journal cross into the yoke cross holes
with grease zerk (nipple) fitting inward toward tub-
ing. The double-headed, grease zerk (nipple) fitting
should be perpendicular to the yoke cross holes.
Failure to properly position the universal joint kit will
result in the inability to grease the universal joint.
Note: If using an arbor press, proceed to step 3. If using a
universal joint tool, follow the manufacturer’s instruc-
tions.
Note: Always inspect bearing cups for rollers that may have
fallen (downed rollers) out of place before installation.
3. Move one end of the journal cross to cause a trun-
nion to project through the cross hole beyond the
outer machined face of the yoke ear. Place the bear-
ing cup assembly over the protruding trunnion diam-
eter and align it to the yoke cross hole.
4. Align the yoke in an arbor press with the bearing
assembly resting on the base of the press. Cover the
yoke ear with a metal plate that has 0.25 inch (6.4
mm) minimum thickness. Push the yoke onto the
bearing cup assembly until it is flush with the cross
hole face.
