To service conventional universal joints, first, mark the joint yokes in relation to each other after removing the driveshaft. Remove the snap-rings from the bearing cups and use two sockets of different sizes to push the bearings out of the yokes, mounting the joint in a vise for this process. Mark the trunnion before removing the remaining bearings and disassemble the universal joint while keeping all components marked for proper reassembly. Clean the driveshaft and components with solvent, inspecting for cracks and damage, and check the trunnion journals and sleeve yoke splines for wear. Replace all needle bearings, cups, washers, snap-rings, and dust seals with new ones during reassembly, packing grease into the trunnion ends and applying grease to the dust seal lips. Carefully install the bearings and trunnion in the yoke, ensuring not to damage the bearing cups, and press the bearing cups into place, followed by installing new snap-rings. For constant velocity joints, mark all yokes before disassembly, disengage the flange yoke and trunnion from the centering ball, and clean and inspect all components for wear, replacing any damaged parts. Lubricate the parts with grease from the repair kit, insert them into the ball seat cavity in the correct order, and attach the flange yoke to the centering ball, ensuring proper alignment before installing the trunnion caps.

The constant velocity joint is essential for most 4-wheel-drive vehicles that experience high torque loads and steep drive line angles.

To check for wear, attempt to turn the shaft with one hand while holding the rear axle flange with the other when inspecting the rear universal joint, and the front half coupling for the front universal joint. Any movement between the driveshaft and the front half couplings, as well as around the rear half couplings, suggests significant wear.
