Answer 1

U-Joint OverhaulExcept Double Cardan Universal # Remove the driveshaft from the vehicle and place it in a vise, being careful not to damage it. # Remove the snaprings, which retain the bearings in the flange and in the driveshaft. # Remove the driveshaft tube from the vise and position the U-joint in the vise with a socket smaller than the bearing can on one side and a socket larger than the bearing cap on the other side. # Slowly tighten the jaws of the vise so that the smaller socket forces the U-joint spider and the opposite bearing into the large socket. # Remove the other side of the spider in the same manner (if applicable) and remove the spider assembly from the driveshaft. Discard the spider assemblies. # Clean all foreign matter from the yoke areas at the end of the driveshaft (s). # Start the new spider and one of the bearing cap assemblies into a yoke by positioning the yoke in a vise with the spider positioned in place with one of the bearing cap assemble positioned over one of the holes in the yoke. Slowly close the vise, pressing the bearing cap assembly in the yoke. Press the cap in far enough so that the retaining snapring can be installed. Used the smaller socket to recess the bearing cap. # Open the vise and position the opposite bearing cap assembly over the proper hole in the yoke with the socket that is smaller than the diameter of the bearing cap located on the cap. Slowly close the vise, pressing the bearing cap into the hole in the yoke with the socket. Make sure that the spider assembly is in line with the bearing cap in far enough so that the retaining snapring cap in far enough so that the retaining snapring can be installed. # Install all remaining U-joint in the same manner. # Install the driveshaft and grease the new U-joints.
