  Q: How to replace the universal joint with a nylon injected ring on GMC Sierra 3500 Classic?

  A:

  You need two tools to change the Universal Joint - start with j 9522-3 u joint bearing separator and j 9522-5 u joint bearing spacer remover. Place the propeller shaft horizontally on a press setup and take care not to put the tubing inside a vise to protect it from injury. Set a mark on the shaft ends before placing the Universal Joint so its lower yoke head fits into a 30 mm socket. To access the lower bearing cup in the yoke ear you need the u joint bearing separator (J 9522-3) to cut the plastic retaining ring before pressing the bearing cup out. Change to the replacement tool j 9522-5 to push the bearing cup completely away from its position. Adjust the propeller shaft rotation to remove the other bearing cup for future reassembly and record its position. Look for dirt or marks in the retaining ring slots and bearing cup wall before cleaning them thoroughly. Place one side of the yoke partially with the bearing cup and put the cross in position to freely fit the trunnion. Insert one bearing cup until it snaps into the yoke ear position on each side while keeping the trunnion alignment straight. Examine the needle bearings immediately after assembly because binding problems with them indicate misalignment. Push the tool until the groove on top of the bearing retainer appears while maintaining proper alignment before installing the bearing retainer and pressing both retainers for perfect fit. When needed use a dead blow hammer for the retainer while chassis grease helps installation.
