  Q: How to replace the universal joint with an external snap ring on GMC Savana 2500?

  A:

  Start the universal joint replacement by obtaining two specialized tools U-Joint Bearing Separator (J 9522-3) and U-Joint Bearing Spacer Remover (J 9522-5). Set the propeller shaft at its horizontal position while keeping hands off from the metal tubing to protect it. Line the propeller shaft ends to ensure it fits correctly later. Pressure off snap rings by clamping them with pliers while using a slight hit from the end of the cup as needed. When using the U-Joint Bearing Separator put the lower yoke on either a 30 mm or 27 mm socket and press the lower bearing cup from the yoke component using the U-Joint Bearing Separator. The process requires the U-Joint Bearing Spacer Remover (J 9522-5) when the bearing cup does not dislodge fully from the seal area. Turn the propeller shaft while pushing out the opposite bearing cup. This marks how the slip yoke fits onto the tube. Examine the grooves of the bearing retainer and bores of both bearings to make sure they are free of dirt and damage before removing the cross and parts. To put the parts together push a bearing cup into one yoke side and fit the cross unit with both trunnions sliding freely. Plunge one bearing cup into the yoke ear until it touches the surface. Do the same for the other side while keeping trunnions parallel. Push the yoke until the retainer hole shows then put on the yoke bearing retainer and keep pushing until both retainers mount securely. When needed use a dead blow hammer to lift up the yoke before putting retainers in place then put chassis grease on the snap ring for better placement into the bearing cup slot.

  Q: How to service and repair the universal joint using the J 9522-3 and J 9522-5 tools on GMC Savana 2500?

  A:

  Make use of both J 9522-3 Universal Joint Bearing Separator and J 9522-5 Universal Joint Bearing Spacer Remover to repair the universal joint. Set the propeller shaft down horizontally in a press while making sure not to put the tubing in a tightening instrument that could harm it. Place dots on the shaft ends to show their correct alignment. Put the universal joint over the 30 mm (1 1/8 inch) socket with the lower yoke ear and press the bearing cup out from the yoke ear by using the J 9522-3 shear tool. Use the J 9522-5 tool when the bearing cup resists coming off by placing it between the seal and cup to push the bearing cup out. Rotate the propeller shaft until the bearing cup of the opposite side come out while noting the slip yoke alignment and removing the cross assembly and universal joint parts. Search for damage on the retaining ring grooves and bearing cup bores before you clean out any sheared plastic that blocks proper reassembly. Put a bearing cup into one yoke side then place the cross so trunnion operates well before pushing bearing cup to match yoke ear. Push the bearing cup into the unused yoke half while making sure trunnions rest properly. Press down while aligning the bearing retainer groove to the yoke before installing both bearing retainers until their snaps lock in place. When needed apply a dead blow hammer to push the retainer in position. Adding chassis grease to the snap ring will help with the insertion process.
