• Q: How to replace the universal joint with a nylon injected ring using special tools on 2009 GMC Envoy?

  A: Special tools J-9522-3 and J-9522-5 allow easy replacement of the universal joint with a nylon injected ring. Position the propeller shaft horizontally on the press system before starting the job to prevent damage to the parts. Locate and note the positions of the propeller shaft's ends before using the 30 mm (1 1/8 in) socket to hold the bottom yoke ear. The U Joint Bearing Separator will sever the plastic holding ring while the lower bearing cup press fully from the yoke ear. The U Joint Bearing Spacer Remover goes between seal and bearing cup to push out the bearing cup when it fails to come out entirely. Use the prop shaft rotation to push the opposite bearing cup out leaving the slip yoke stance notated for later reinstallation. Check both retaining ring groves and bearing cup bores on the yoke to find any surface damages before removing them. Remove all sheared plastic from the grooves before installing new bearing cups. You must place the yoke ear down and insert one bearing cup half-way into the part before fitting the cross effectively. Push the bearing cup into the yoke until it reaches the surface and then push half the second bearing cup. Press the final bearing cup sideways when its trunnions fit straight. Check needle bearing alignment because of this action. Press the tools until the bearing retainer slot meets the yoke opening then build the assembly parts and press them until the retainers lock into place. Use a dead blow hammer to partially push the yoke but do not force it. Apply chassis grease to the snap ring when placing it into the bearing cup groove.
