  Q: How to replace the universal joint with a nylon injected ring on Chevrolet Express 3500?

  A:

  You need two tools to replace the universal joint with a nylon injected ring: U Joint Bearing Separator (J9522-3) and U Joint Bearing Spacer Remover (J9522-5). Rest the propeller shaft horizontally on the press for replacement while keeping the tubing away from the vise for safety. Note the correct placement of the propeller shaft ends ahead of setup. Place the universal joint with its lower yoke ear onto a 30 mm (1 1/8 inch) socket. Use the U Joint Bearing Separator tool part J9522-3 to cut the plastic retaining ring of the bearing cup before pressing out the lower bearing cup through the yoke ear. When the bearing cup refuses to come loose put the U Joint Bearing Spacer Remover between the seal and the cup then proceed with pressing. Turn the propeller shaft to drive out the bearing cup from its housing. Check the retaining ring grooves and bearing cup bores for damage during inspection of the assembled parts before cleaning sheared plastic from them. Place one bearing cup inside the yoke before you position the cross to engage the trunnion without resistance. Push each bearing cup even with the yoke end while making sure trunnions stay in the proper position. Check if the needle bearings prevent proper movement since they may need adjustment. Push the bearing retainer to its proper position and then put on both pieces with a dead blow hammer as needed. Add chassis grease to the snap ring when necessary to help it fit properly into the bearing cup groove.

  Q: How to service and repair the universal joint on Chevrolet Express 3500?

  A:

  Begin your Universal Joint service and repairs work after placing safety stands under the vehicle to lift it up. Do not put the propeller shaft in a vise because this can damage the shaft tubing while you remove it. Avoid touching the smooth bottom of the slipping yoke and do not hit the yoke ear areas. Mark the position of the yoke pairs after you take off their retaining elements. To separate Universal Joint bearing cups from either the yoke or propeller shaft apply j 9522-3 u-joint bearing separator in a press tool to extract the bearing cups while safeguarding their seals. Look for problems in both ring grooves and bearing cup bores on the Slip Yoke after you take it off the propeller shaft. Clean the grooves when needed. Use new bearing cups during installation and line them up correctly to prevent installation problems. Press the bearing cup into the yoke ear or propeller shaft with gentle force until the cup seal takes its place. Build the propeller shaft assembly by repeating this step until complete and put back the propeller shaft followed by uninstalling safety stands when lowering the vehicle.
