  1. Remove the bearing cups from the universal joint.

  3. Assemble the cross into the yoke so that the trunnion seats freely into the bearing cup.

  4. With the trunnion seated in the bearing cup, press the bearing cup into the yoke until the bearing cup is flush with the yoke ear.
  5. Install the opposite bearing cup part way into the yoke ear.
  6. Ensure that the trunnions start straight and true into both bearing cups.
  7. 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.
  8. Press the bearing cup into the yoke until the bearing cup retainer groove is visible over the top of the bearing cup.
