You can Select Your Vehicle to check if YL8Z-3A331-BA fits your vehicle.

You can evaluate shock absorbers by pushing down and releasing the vehicle at each corner. Observe whether the vehicle returns to a level position within one or two bounces and listen for any squeaks. Inspect the shocks for fluid leakage and ensure they are securely mounted and undamaged.

The removal of the inner CV joint and boot involves cutting off the boot clamps, pulling the boot back from the joint, and sliding the joint housing off. It's important to mark the relationship between the tripod and the outer race. Next, a center punch is used to mark the tripod and axleshaft to ensure proper reassembly. The stop-ring ends are spread apart, moved towards the shaft's center, and the retainer clip is removed from the axleshaft end. The tripod joint is driven off the driveaxle with a brass punch and hammer, ensuring the bearing surfaces or the shaft's splines are not damaged. The stop-ring is then removed from the axleshaft and discarded.

During reassembly, the clamps and boot are slid onto the axleshaft, taking care to wrap the splines with tape to prevent boot damage. A new stop-ring is installed on the axleshaft, positioned past its groove, and a new bearing retainer clip is installed. The tripod is then placed on the shaft with aligned marks, the stop-ring is seated in its groove, and the joint housing and boot are packed with CV joint grease. The boot is slid into place and pressure inside it is equalized by inserting a small, dull screwdriver between the boot and the outer race. The boot clamps are tightened using appropriate tools and methods. The driveaxle assembly is then installed.

At the rear of the vehicle, assess suspension arm bushings for deterioration. Inspect drive axle boots, especially the outer CV boot, for tears, cracks, and loose clamps. It's also a good practice to wash drive axle boots to prevent premature deterioration caused by oil and grease. Replace any boots that show evidence of cracks, leaking lubricant, or damage.
