For this procedure, a press or a large vise will be necessary and it may be simpler to take the driveshaft to a local dealer or a machine shop for replacement of the universal joint at a reasonable cost. First disassemble by taking out the driveshaft. By now you would have realized that some disassembling of the spider may be necessary; using a small pair of pliers remove the snap-rings from the spider, you might need to use needle-nose pliers here. Secure the driveshaft and align it in such a manner that can be placed on an arbor press or placed on the workbench with vise. Put one bearing cap with a piece of pipe or with another large socket where the inside diameter is the same at one side of the crank and fit another socket slightly smaller over the cap on the other side of the crank. With the vise or press, apply pressure until the cap partially comes out of the yoke but do not fully remove it out; the fully removal has to be done with the vise or large pliers. Remove the bearing caps on the other side and place the sockets on the opposite side again pushing out the other bearing cap in the same way. After that, lubricate the new universal joint bearings with the help of grease that has to be packed with the servicing kit, if there are special instructions where to grease the bearings. Fit one of the bearing caps partly into the yoke and set the spider into the cap, then start the spider into the other cap and fit it part way. Position the spider and engage the bearing caps and bear in mind that the dust seals should not be marred. Place the snap-rings and in case of a hard time getting them to seat back into the groove, slight tapping of the driveshaft yoke will do the trick. If the snap-ring still does not seat it is advisable to use brass hammer to spring the yoke ears slightly. Fit in a grease fitting and then pump the joint with grease but don't overfill so you don't end blowing out the grease seals. Last, but not the least is the installation of the drive shaft followed by the tightening of the flange bolts to a recommended torque value.
