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

  A:

  Repairing a Universal Joint with an external snap ring requires use of these tools: the proper tools for this task include u-joint bearing separator (J 9522-3) together with u-joint bearing spacer remover (J 9522-5). U-joint bearing separator (J 9522-3) and u-joint bearing spacer remover (J 9522-5). Set the propeller shaft horizontally on a press for support while maintaining the tubing out of vise contact to protect it from damage. Make identifying marks on the propeller shaft to show its connection points with the transmission and rear axle assembly. Use pliers to pinch snap ring ends for disassembly and tap the cup end lightly to reduce pressure when needed. Free the supporting surface of the Universal Joint by using a 30 mm (1-1/8 inch) hex head socket or a 27 mm (1-1/16 inch) socket before using the u-joint bearing separator (J 9522-3) for bearing cup removal from the yoke ear. To press out the bearing cup which will not dislodge completely a u-joint bearing spacer remover (J 9522-5) needs to be placed between the bearing cup and the seal. The rotating propeller shaft exerting pressure on the opposing bearing cup requires you to note the Slip Yoke position for reinstallation. Examine both the bearing cup bores and retaining ring grooves for cleanliness while looking for any imperfections. Remove the cross and discarded Universal Joint parts from the assembly. Position a bearing cup on one yoke side followed by the cross assembly then apply pressure until the cup rests flush with the ear. Move through this process again on the different side of the yoke while checking that all trunnions remain correctly oriented. Run the press tool until you can see the retainer groove before you position the bearing retainer. Keep pressing until both retainers securely lock into place. The dead blow hammer can lightly press the yoke when needed to help with retainer placement while chassis grease applied on the bearing cup edges will assist with correct seating.
