Disassembly Procedure

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2007 GMC Yukon XL, 2007 GMC Yukon, 2007 Chevrolet Tahoe, 2007 Chevrolet Suburban, and 2007 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE: Never clamp propeller shaft tubing in a vise. Clamping could dent or deform the tube causing an imbalance or unsafe condition. Always clamp on one of the yokes and support the shaft horizontally. Avoid damaging the slip yoke sealing surface. Nicks may damage the bushing or cut the lip seal.
  1. Support the propeller shaft in a line horizontal with the table of a press.
  2. Mark the propeller shaft as to which end is the transmission end and which end goes to the rear axle.

  4. In order to shear the plastic retaining ring on the bearing cup, place J 9522-3  on the open horizontal bearing cups. See Special Tools . Press the lower bearing cup out of the yoke ear.
  5. If you do not completely remove the bearing cup, lift the cross and insert J 9522-5  between the seal and the bearing cup you are removing. See Special Tools . Continue to press the bearing cup out of the yoke.
  6. Rotate the propeller shaft. Press the opposite bearing cup out of the yoke.
  7. Mark the orientation of the slip yoke to the tube for proper reassembly.
  8. Remove the cross from the yoke.
  9. Remove the remaining universal joint parts from the yoke. If you are replacing the front universal joint, remove the bearing cups in the slip yoke in the same manner.
  10. Inspect the retaining ring grooves for plastic.
  11. Inspect the bearing cup bores in the yoke ears for burrs or imperfections.
  12. Clean the remains of the sheared plastic bearing retainers from the grooves in the yoke.
  13. The sheared plastic may prevent the bearing cups from pressing into place and thus prevent the bearing retainers from properly seating.
