How to replace the universal joint with an external snap ring on GMC Savana 2500?

Question

Accepted Answer

To replace the universal joint with an external snap ring, begin by gathering the necessary tools: The required tools include U-Joint Bearing Separator (J9522-3) and U-Joint Bearing Spacer Remover (J9522-5). Keep the propeller shaft in horizontal position during maintenance while also avoiding any tubing clamps that can harm the system. Make clear marks on the propeller shaft ends so it can be correctly reassembled. You should pull the snap rings apart using pliers before occasionally using a tool to tap the cup's end and reduce pressure. To remove the lower bearing cup from the yoke ear first stabilize the yoke ear using either a 30 mm (1-1/8 inch) hex head socket or a 27 mm (1-1/16 inch) socket then use the U-joint Bearing Separator (J9522-3) to push the bearing cup out of its position. Use the U-Joint Bearing Spacer Remover (J9522-5) to separate further a bearing cup that doesn't completely leave its position by placing it between the seal and the cup. Rotating the propeller shaft enables bearing cup extraction while marking the slip yoke orientation relative to the tube. Examine the bearing cup bores and retaining ring grooves after removing the cross and universal joint parts while checking for cleanliness as well as imperfections. To assemble the yoke slide one bearing cup into its side where the trunnion fits easily before pressing the cup until it matches the yoke's ear. Install the second bearing cup on the yoke after ensuring trunnions point directly straight and then press it into the yoke until it shows free movement. Examine the needle bearings for misalignment whenever binding occurs. To finalize the bearing retainer assembly press until both retainers snap into position after the retainer groove becomes visible. A firm strike from a dead blow hammer and chassis grease application on the snap ring may help seat the retainer when difficulty arises during installation.
