Remove the bearing cups from the universal joint.
Assemble 1 bearing cup part way into 1 side of the yoke. Turn the yoke ear toward the bottom.
Assemble the cross into the yoke so that the trunnion seats freely into the bearing cup.

Ensure that the trunnions start straight and true into both bearing cups.
Press the opposite bearing cup into the yoke ear while working the cross all the time in order to inspect for free unbinding movement of the trunnions in the bearing cups.

IMPORTANT: If there seems to be a hang up or binding, stop pressing. Inspect the needle bearings for misalignment in the bearing cup.

Press the bearing cup into the yoke until the bearing cup retainer groove is visible over the top of the bearing cup.
Assemble the bearing retainer in the retainer groove.

If the retainer is difficult to seat, the yoke can be sprung slightly with a firm blow from a dead blow hammer.

It may be necessary to lubricate the snap ring with a slight amount of chassis grease so that the snap ring seats in the bearing cup groove.
