It is advisable to involve a professional in the process of removing and replacing universal joints on a driveshaft. The process involves marking the positions of spiders, the center yoke, and the centering socket. Remove snap-rings and press out bearing cups. Then remove the spider from center yoke. Remove the centering socket yoke, and snap-rings from center yoke, and driveshaft yoke respectively. Press bearing out and separate the spider from the center yoke. Clean all the parts before packing new universal joint bearings with grease. The slip joint must be carefully pulled out of the driveshaft for inspection purposes only. After this, it should be lubricated, reassembled, and secured using a new dust boot seal as well as clamps. Start by placing spider into driveshaft yoke, installing bearing cups, securing them with snap-rings, pack socket relief and ball with grease before pressing center yoke into such position.
