Depending on the intensity of worn out universal joints, a press or large vise will be necessary for the procedure and it is wise to drop the driveshaft to a repair or machine shop for the replacement at a reasonable cost. As earlier described, begin by pulling out the driveshaft in the following manner. With the help of small pliers, remove the snap-rings from the spider - as for this, you need snap-ring pliers. Place it on the centre of an arbor press or embed it on a workbench in a vise for proper support. Slide a piece of pipe or a large socket with the same inside diameter over one of the bearing caps, put a slightly smaller socket over the other cap. You can simply push the cap with the vise or press and hold it tightly inside yoke and than with the same vise or large pliers seize the bottom of the cap and twist it fully outside yoke. Move the sockets to the other side and, using the same procedure, tap out the other bearing cap. Apply the grease to the new universal joint bearings as per the directions given in the servicing kit and ensure as well the new bearings have been also greased. Place the spider in the yoke and snugly fit one bearing cap into its seat; if the new spider has a grease fitting, its hole is to be parallel to the driveshaft, and the fitting will be offset. Begin spinning the spider onto the bearing cap and get the other somewhat mated and have the spider and press the bearing caps into place which some force without deforming the dust seals. Cook the yoke with the snap-rings if there is tightening resistance and these should be set into the groove by hamming. Screw in the grease fitting and pump the joint with grease; do not over grease the joint as this may blow the grease seals. Lastly, fit the driveshaft and torque the bolts and nuts for the flange to its manufactures recommended torque.
