Q: How to disassemble and assemble CV joints and CV Boot?
A: When dealing with potentially worn CV joints, it's wise to consider alternatives before diving into an overhaul, particularly if wear is due to torn CV Boot. Check the availability and cost of replacement parts and complete rebuilt drive axles on an exchange basis before proceeding with the job. To disassemble the inner CV joint, securely mount the drive axle in a bench vise with wood blocks for protection and remove the boot retaining clamps, sliding the inner boot back. Then, pull off the inner CV joint housing from the shaft and tripod, remove the snap-ring from the shaft using snap-ring pliers, mark the shaft and tripod, and take off the tripod. Afterward, remove the boot, clean the housing and tripod with solvent, and thoroughly inspect them for wear or damage; if found, replace the entire joint. For assembly, apply CV joint grease to the tripod and interior of the housing, insert the shaft and tripod into the housing after positioning the boot correctly, and secure the boot clamps. To disassemble the outer CV joint, mount the axleshaft in a vise with wood blocks, remove the boot clamps and slide the boot back. Wipe away the grease and expand the snap-ring retaining the outer joint to the shaft with snap-ring pliers to remove the joint. After sliding off the boot from the drive axle, inspect the axle spline area for damage and corrosion, clean the outer CV joint bearing assembly, and mark the relative positions of the bearing cage, inner race, and housing. To disassemble the bearing assembly from the housing, tilt it vertically and align opposing cage windows between the ball grooves. Turn the inner race 90 degrees to the cage, align a spherical land with an elongated cage window, and raise the land into the window to separate the two components. Clean all parts with solvent and inspect for damage, corrosion, wear, or cracks; if unserviceable, replace the entire CV joint assembly with a new one. For assembly, apply a thin film of oil to all CV joint components and align the marks when installing the inner race in the cage and the assembly in the housing. Ensure the large counter bore of the inner race faces out, and fill the joint with grease through the splined hole while inserting wooden dowels to force the grease in. Slide the inner clamp and boot over the drive axle, place the CV joint housing in position, align the splines, and push it into place. Secure it by attempting to pull it from the shaft, ensure the boot is undistorted, and then tighten the clamps.
