Before disassembly, scribe alignment marks on yoke and shaft for reassembly. If joints are rusted or corroded, apply penetrating oil before pressing out bearing cups or trunnion pin. CROSS SHAFT & ROLLER TYPE UNIVERSAL JOINTS Snap rings or injected plastic retainers may be used to retain bearing cups. Joints with snap rings may be disassembled and reassembled using same cross shaft and bearings. Joints with nylon retainers are disassembled by breaking nylon retainers; install NEW nylon retainers after service, or replace joints with joints that use snap rings. Removal & Disassembly 1. Disconnect yoke or flange attaching bolts and remove drive shaft from vehicle. DO NOT use a pry bar to hold drive shaft while loosening bolts, or damage to bearing seals may result. Scribe marks on yoke and shaft for reassembly reference. 2. Remove retaining strap (if equipped). Remove bushing retainers/snap rings from yoke. Press out bearing cups. Remove last bearing cup by pressing on end of cross shaft. 3. Remove cross shaft assembly from yoke. DO NOT remove seal retainers from cross shaft. Cross shaft and retainers are serviced as an assembly. Reassembly & Installation 1. Coat roller bearings with lubricant. Fill bearing cups with grease. Place cross assembly in drive shaft yoke. Place bearing cups in position. 2. Press both bearing cups into yoke until retainers/snap rings can be installed. Ensure cross stays aligned in center of bearing cups while pressing into place. Install retainers/snap rings. Repeat procedure for remaining bearing caps. Install strap (if equipped). Install drive shaft in vehicle. Ensure scribed marks on yoke and shaft are aligned.
