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

  A:

  Before installation set the propeller shaft on a flat press table with nylon technology and never place the prop shaft tubing in a vise to prevent damage. Exercise caution and label the propeller shaft ends for their correct position. Place the yoke universal joint onto the 30 mm (1 1/8 inch) socket with its lower ear. Use the J9522-3 U Joint Bearing Separator to cut off the plastic retaining ring on the bearing cup then press the bottom bearing cup out of the yoke ear. Set your tools aside and fit the U Joint Bearing Spacer Remover (J9522-5) between the seal and bearing cup before continuing to push. Turning the propeller shaft pushes out the other bearing cup from its location. Check grooves of the retaining rings and bores of the bearing cups for damages after taking out the parts and the cross. Use proper tools to clean all sheared plastic from bearing cup grooves before fitting them into position. Insert one bearing cup into one yoke's side and place the cross with trunnion free installation. Push the bearing cup into the yoke until it rests flat and do the same with the opposite bearing cup to match the trunnion positions. Check if the needle bearings move easily during this test. Push firmly until the bearing retainer clear space appears inside the yoke and then put together the bearing retainer before pressing to lock both retainers in place. A dead blow hammer can aid installation if needed while you should apply chassis grease to the bearing cup groove to help the snap ring slide more easily.

  Q: What tools are required to service and repair the universal joint with an external snap ring on Chevrolet Blazer?

  A:

  You need U-Joint Bearing Separator J. 9522-3 and U-Joint Bearing Spacer Remover J 9522-5 to work with external snap ring universal joints. Set the propeller shaft on a press table horizontally before starting any work to shield its tubing from harm. Use a marker to show where the transmission and rear axle connect to the propeller shaft. Using pliers squeeze the snap ring ends to open it then tap gently on the cup end if needed to reduce internal stress. Put the lower yoke ear on a 30mm hex head socket or 27mm socket and place U-joint Separator J 9522-3 on open horizontal bearing cups to extract the lower bearing cup from the yoke ear. Insert the U-Joint Bearing Spacer Remover (J 9522-5) between the seal and the bearing cup after lifting the cross to remove the spacer. Continue to push while passing the bearing cup. Use the propeller shaft rotation to remove the second bearing cup while marking the slip yoke setup position. Examine all grooves and bores in the bearing cups and retaining rings to check for cleanliness and damage near the parts' removal. Place half a bearing cup in one yoke ear first and join the trunnion smoothly into the assembled cross section. Use consistent force to press the bearing cups into their matching yoke ears and check for correct trunnion matching. Push downward until the bearing retainer grooves show and add the retainer parts before completing the press action when both parts click into position. A light strike from the dead blow hammer and chassis grease added to the snap ring make it easier to install the retainer properly.
