Q: How to universal joint replacement for Chevrolet C1500 and K1500?A: Before beginning the universal joint replacement procedure, it's crucial to have a universal joint service kit specific to your vehicle. First, remove the driveshaft. For the outer snap-ring type universal joint, place the driveshaft on a bench equipped with a vise. Remove the snap-rings using small pliers, then support the cross (also called a spider or trunnion) on a short piece of pipe or a large socket and use another socket to press out the cross by closing the vise. Press the cross through as far as possible, grip the bearing cup with locking pliers, and remove it. A universal joint repair kit will provide new components like a trunnion, seals, bearings, cups, and snap-rings. Inspect the bearing cup housing in the driveshaft for wear and damage; if it's too worn, the driveshaft will require replacement. Ensure the dust seals are correctly positioned on the trunnion. Using a vise, press one bearing cup into the yoke about 1/4-inch, use grease to keep the needle rollers in place, insert the trunnion into the partially installed bearing cup, insert the needle bearings into the opposite cup, and press both cups into place using a slightly smaller socket. Install the snap-rings to secure the cups. For the injected plastic (inner snap-ring) type, if the joint has been previously rebuilt, remove the snap-rings located on the inner part of each bearing cup. For first-time rebuilding, it won't be necessary to remove the snap-rings; the pressing operation will shear the molded plastic retaining material. Press out the bearing cups, remove the trunnion (cross), and clean all plastic material from the yoke. Reassembly is similar to the outer snap-ring joint, but the snap-rings are on the inner part of each bearing cup. When installing the bearing cup, press it in until the snap-ring can be installed, and if needed, strike the yoke with a hammer to allow the snap-ring groove to move into position.
