Complete rebuilt CV Boots are available on an exchange basis, which eliminates much time and work, so it's advisable to check on the cost and availability of parts before disassembling the vehicle. Begin by removing the CV Boot and mounting it in a vise with wood-lined jaws to prevent damage to the axle shaft. Inspect the CV joint for excessive play in the radial direction, indicating worn parts, and ensure smooth operation throughout the full range of motion for each CV joint. If a boot is torn, disassemble the joint, clean the components, and inspect for damage due to loss of lubrication and possible contamination. Cut off and discard the old boot clamps, then carefully pry up the edge of the outer boot and push it away from the CV joint. Pull the inner CV joint boot back from the housing and slide the housing from the tripod, marking the tripod and axleshaft for proper reassembly. Remove the tripod joint snap-ring with snap-ring pliers and use a hammer and brass punch to drive the tripod joint from the CV Boot, taking care not to damage the bearing surfaces or splines. Clean all components thoroughly with solvent, inspecting the bearing surfaces for cracks, pitting, and other signs of wear. If the inner CV joint is worn, a new inner CV joint can be installed on the old axleshaft; if the outer CV joint is worn, a new outer CV joint and axleshaft must be purchased. Check the condition of the support bearing on the intermediate shaft, ensuring it turns freely and smoothly; if not, have it replaced. To reassemble, wrap the splines on the inner end of the axleshaft with electrical or duct tape to protect the boots, then slide the clamps and boots onto the axleshaft, placing the tripod on the shaft and installing a new snap-ring. Apply grease to the tripod assembly and inside the housing, insert the tripod into the housing, and pack the remainder of the grease around it. Ensure the boots are seated in their respective grooves on the axleshaft, position the inner CV joint midway through its range of travel, equalize the pressure in the boot, and tighten the boot clamps. The CV Boot is now ready for installation.

To check shock absorbers, push down and release the vehicle at each corner. If the vehicle doesn't return to a level position within one or two bounces, the shocks/struts are likely worn and should be replaced. Worn shocks/struts can cause symptoms such as excessive body movement on rough roads. While bouncing the vehicle, listen for squeaks and noises from the suspension components.
