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

  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.

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

  A:

  To replace the Universal Joint with an external snap ring, first, you should lay the propeller shaft on the press table horizontally so as not to damage the tubing by clamping it in a vice. Tag the propeller shaft to show the transmission and rear axle connections. Disassemble using pliers the snap rings and, if needed, tap the cup end lightly to relieve pressure. Start the support of the lower ear of the yoke onto 30 mm (1-1/8 in) hex head socket or onto 27 mm (1-1/16 in) socket and then to place j 9522-3 onto the open horizontal bearing cups in order to press the lower bearing cup out of the yoke ear. If the bearing cup fails to come out all the way, raise the cross and place j 9522-5 in between the seal and bearing cup to keep pressing it out. Rotate the propeller shaft to drive out the opposite bearing cup and note the orientation of Slip Yoke to tube that one therefore needs for reassembling. Remove the cross & other universal junt event as well and in the case of changing the front Universal Joint, take off bearing cups found on the Slip Yoke as well. Check retaining ring groove and bearing cup bore for cleanliness and imperfections and cleaning where necessary. For assembly, take bearings cups off from the Universal Joint and have one of the bearings cups half assembled into the one end of the yoke while the yoke ear is pointing down. Place the cross on the ends of the trunnion such that the trunnion fits freely in the bearing cup and push the bearing cup into the yoke until its flush with the yoke. Mount one of the opposite bearing cups partially inside a yoke ear making sure that the trunnions are pointing straight into the bearing cups. Press the contrary bearing cup as you check for the free movement of trunnions; if there is binding, check the needle bearings for misalignment. Press further applying pressure, up until you see the bearing cup retainer groove, then install the bearing retainer into the groove and press everything until both retainers snap into place. If fitting the retainer becomes difficult than a firm hammer blow from the kind of dead hammer (which is intended for such blow on snap ring) can help, and a little of the chassis grease can help paint the grease on the snap ring to smooth the entry.
