2004 Chevrolet Blazer Universal Joint Parts and Q&A

• Q: How to replace the universal joint with an external snap ring on 2004 Chevrolet Blazer?

  A: Start your universal joint replacement project by getting both the J9522-3 U-Joint Bearing Separator and J9522-5 U-Joint Bearing Spacer Remover tools. Position the propeller shaft horizontally and steer clear of tube contact that can hurt the parts. Note the propeller shaft ends before you take it apart. Use pliers to take apart snap rings and work the cup end with a tap if the joint does not release pressure. Place the U-Joint Bearing Separator (J9522-3) between open horizontal bearing cups then apply it to the lower yoke ear's support surface while using a 30 mm or 27 mm socket head. When the first bearing cup fails to extract push the U-Joint Bearing Spacer Remover (J9522-5) between the seal and the cup. Keep pushing to push out the besing cup. When rotating the propeller shaft you push one bearing cup toward the slip yoke position to determine tube fitting with the yoke. Examine all bearing cup grooves and bores inside the yoke for any signs of damage before processing the parts for reassembly. Place one bearing cup into the yoke opening so its trunnion fit smoothly before pushing it until flush with the ear surface. Press the other bearing cup into position while keeping trunnion alignment right and verifying its movement. Check if the needle bearings face each other properly when unsatisfactory movement occurs during assembly. After seeing the bearing cup retainer groove you must add the bearing retainer blocks and keep pushing until they snap into position. A dead blow hammer works well to fully install the retainer. Apply chassis grease over the snap ring to simplify its placement within the bearing cup groove.
