Mercury F2AZ-4635-C Universal Joint Repair Kit

To replace single-cardan U-joints, make sure you have a press or vise and a universal joint service kit. First, take off the driveshaft and use pliers to remove snap-rings from the spider. Then place the driveshaft on a workbench with a vise. Sockets should be used to press bearing caps out of the yoke. Fill new universal joint bearings with grease, and position the spider and caps before pressing them into place; do not forget snap-rings. Dust seals must not be damaged. Add grease and mount the driveshaft. Cardan U-joints should have rings removed and positions marked. Remove bearing caps in the center yoke and driveshaft yoke. Replace the centering ball and dust cover on the companion flange. Disassemble the center yoke and driveshaft yoke, and install new spider bearing in the driveshaft yoke. Insert new caps and seals with grease fitting facing away from the center yoke.
