  Q: How to replace the universal joint with an external snap ring on GMC Sierra 3500?

  A: The replacement requires two special tools: J 9522-3 U-Joint Bearing Separator and J 9522-5 U-Joint Bearing Spacer Remover. Keep the propeller shaft flat as you start the replacement to prevent damaging the tube when positioning it in a clamp holder. Identify which side of the propeller shaft connects to the transmission and the rear axle. Use pliers to take apart the snap rings and hit the end of the cup gently when needed. Rest the lower yoke ear on a 30 mm hex socket or 27 mm socket. Put the U-Joint Bearing Separator (J 9522-3) in the horizontal bearing cups. Press the bottom bearing cup out of the yoke ear while supporting the ends horizontally. When the bearing cup remains stuck lift the propeller shaft cross to insert U-Joint Bearing Spacer Remover J 9522-5 between seal and cup for further pressing out. Adjust the propeller shaft spin to push the opposite bearing cup from its position while noting how the yoke connects to the tube for proper reinstallation. Examine both bearing cup bores and retainer ring grooves for damage while inspecting them for dirty or damaged parts. Press one bearing cup into half of the yoke part before attaching the cross to center the trunnion properly. Push the bearing cup straight into the yoke until its face rests flat against the surface and do the same on the opposite side to align trunnions. Check to see if the bearing cup retainer groove is showing while pressing down on the cup. Test the needle bearings when you feel binding pressure. Insert the bearing retainer in the groove while pressing uniformly until it locks. Use a dead blow hammer to secure both retainers if required followed by grease application to ensure better retention.
