Reassembly - Snap Ring Design
Please refer to the Universal Joint information in the Compo-
nent Safety section on page 2.
1. Using a high quality N.L.G.I., grade 2 extreme pres-
sure (E.P.) grease, apply adequate grease to each
bearing cup assembly. Fill all the cavities between
the needle rollers, and also apply a liberal coating of
grease in the bottom of each bearing cup and on the
lip of the seal. Be careful not to get grease on the
outside machined surface of the bearing cup.
2. Position the journal cross in the yoke cross holes
with the grease zerk (nipple) fitting inward toward
the tubing.
Failure to properly position the univer-
sal joint may result in the inability to lubricate the
universal joint.
If using an arbor press, proceed to
Step 3. If using a universal joint installation tool, fol-
low the tool manufacturer’s instructions.
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. Check the bear-
ings for skewed or dropped needle rollers. Place the
bearing cup assembly over the protruding trunnion
diameter and align it to the yoke cross hole. 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 .150" (6.4 mm) minimum
thickness. Push the yoke onto the bearing cup
assembly until it is flush with the cross hole face.
4. Place a push rod that is smaller than the diameter of
the bearing cup assembly under the bearing cup
assembly, and continue pressing into the yoke cross
hole until a snap ring can be installed.
5. Remove the yoke from the arbor press. Install a snap
ring using snap ring pliers.
