Assembly Procedure

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 GMC Yukon XL, 2003 GMC Yukon, 2003 Chevrolet Tahoe, 2003 Chevrolet Suburban, and 2003 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove the bearing cups from the universal joint.
  2. Assemble 1 bearing cup part way into 1 side of the yoke.
  3. Turn the yoke ear toward the bottom.
  4. Assemble the cross into the yoke so the trunnion seats freely into the bearing cup.
  5. 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.

  6. Assemble the opposite bearing cup part way into the yoke ear.
  7. Ensure that the trunnions start straight and true into both bearing cups.
  8. Press the opposite bearing cup into the yoke ear while working the cross all the time in order to inspect for a free unbinding movement of the trunnions in the bearing cups.
    IMPORTANT: If there seems to be a hang up or binding, stop pressing, and inspect the needle bearings for misalignment in the bearing cup.
