Q: What is the importance of driveaxle boots and how should they be maintained on Chevrolet Equinox and GMC Terrain?
A: The CV boots are essential in preventing dirt, water, and other foreign materials from entering and damaging the constant velocity (CV) joints. Since oil and grease tend to wear out the material of the boot, it should be washed using soap and water. The outer CV boot wears out earlier than the inner one because it is constantly moving back-and-forth with the steering action of the front hub; hence, there is a need for regular inspection. Additionally, one should also inspect them for cuts, cracks, or clamps that may have become loose. This includes checking both inner and outer CV boots for leaking lubricant, or any signs of worn clamps such as cracks present in them. There is no difference between them and all-wheel-drive models that have driveaxles at their rear ends as well. Replacements are needed if they have any signs of cracking or if there is any leaked lubricant.
Q: How to remove and replace the inner and outer CV joint and boot of a driveaxle for Chevrolet Equinox,GMC Terrain and Pontiac Torrent?
A: To remove and replace the inner CV Joint and boot of a drive axle, start by removing the drive axle from the vehicle and mounting it in a vise lined with wood or rags. Use a center punch to mark the tri-pod and Axle Shaft for proper reassembly. Remove the stop-ring from the axle shaft and discard it. Clean the old grease from the outer race and tri-pod bearing assembly, inspecting for abnormal wear. To reassemble, slide the clamps and boot onto the axle shaft, install a new stop-ring, place the tri-pod on the shaft, and install a new bearing retainer clip. Apply CV joint grease, slide the boot into place, equalize the pressure, tighten the clamps, and install the drive axle assembly. Remove and discard the bearing retainer clip and slide the boot off the axle shaft. Clean all components and inspect for wear. To reassemble, slide a new sealing boot clamp and boot onto the axle shaft, place a new bearing retainer clip, add grease to the outer CV joint assembly housing and sealing boot, align the splines, and drive the CV joint onto the axle shaft.
