  Q: What tools are needed to service and repair the universal joint with a nylon injected ring on Chevrolet Avalanche 2500?

  A: Repair or service the universal joint containing a nylon ring by using tool set J 9522-3 and J 9522-5. Two necessary tools include U Joint Bearing Separator (J 9522-3) and U Joint Bearing Spacer Remover (J 9522-5). The first step should include supporting the propeller shaft horizontally on a press but avoid clamping the tubing in a vise because this could cause damage. Record clear markings at both ends of the propeller shaft to maintain the correct orientation. Set the universal joint within the lower yoke ear on a 30 mm (1 1/8 inch) socket. Proceed by using the U Joint Bearing Separator (J 9522-3) to divide the plastic retaining ring on the bearing cup before pressing the lower bearing cup out of the yoke ear. The U Joint Bearing Spacer Remover (J 9522-5) allows users to press out remaining bearing cups by placing it between the seal and the cup. The propeller shaft rotation will force the opposite bearing cup to exit before removing the cross piece as well as any leftover universal joint elements. Check the retaining ring grooves together with bearing cup bores for any signs of damage before cleaning them both. To assemble the yoke you must first drive a bearing cup into one yoke side while you position the cross to accept the trunnion without restriction. Pressibrate the bearing cup until it fully masters the yoke ear then perform these steps for the other side making sure trunnions maintain correct alignment. Check the needle bearings for misalignment in case binding takes place. Use the press tool to drive the bearing retainer groove out of the yoke before installing the retainer snap ring. A dead blow hammer can help you set the retainer correctly if required. Application of chassis grease to the snap ring may help its correct positioning within the bearing cup groove.
