GMC 26008858 Propeller Shaft Universal Joint Kit

To remove the driveshaft, start by placing it on a bench equipped with a vise. Use a small pair of pliers to remove the snap-rings. Support the cross on a short piece of pipe or a large socket and press it out by closing the vise. Grip the bearing cup with locking pliers and remove it. Inspect the bearing cup housing for wear and damage. If necessary, replace the driveshaft. Make sure the dust seals are properly located on the trunnion. Press a bearing cup into the yoke and use multi-purpose grease to hold the needle rollers in place. Insert the trunnion into the bearing cup and press both cups into place. Use a socket to press them into the yoke and install the snap-rings. Repeat these steps for the remaining bearing cups. For the injected-plastic type, remove the snap-rings on the inner part of each bearing cup. Press out the bearing cups and remove the trunnion. Clean all plastic material from the yoke and reassemble the joint using the same steps as the outer snap-ring joint, but with the snap-rings on the inner part of each bearing cup. If difficulty is encountered during installation, strike the yoke with a hammer to allow the snap-ring groove to move into position.
