Question 1

Should the CV Joint Boot be inspected periodically to prevent excessive tire wear and handling issues on Audi A4?

Accepted Answer

The steering linkage and the suspension parts are to be inspected on a regular basis because the worn and damaged components may cause excessive wear of tires, poor ride quality, handling, and lower fuel economy. Checking shock absorbers requires parking the vehicle on flat floor, and switching off the engine and putting on the parking brake after which tire pressure is checked. To test the vehicle, press on one corner of the vehicle and release it and it ought to stop and go back to the level position in one or two bounces and in the event that it does not, the shock absorber might be defective or old. Check this at the other corners repeatingly and then ensure that the vehicle has been elevated safely on jackstands. Examine the shock absorbers to confirm that the fluid is not leaking and the fluid that is detected should be a result of the shocks after which they should be replaced as a set. Make sure that the shocks are firmly installed, make sure that they are not worn or damaged at the upper mounts, and change them, where necessary. To perform the steering and suspension inspection, visually inspection of all parts should be done to determine whether there is damage, distortion and leaks, especially around the bushings where the control arms connect with the chassis. Wipe out the lower end of the steering knuckle and also have someone to move the wheel in-and-out in monitoring any movement in the balljoint and any movement would show that it required replacement. Check play in the components of the steering system by grabbing each of the front tires and checking them to see whether there is looseness in the steering gear mounts and tie-rod ends. Finally, check the driveaxle boots in case of tears, cracks and loose clamps and they prevent the dirt and damage of the constant velocity joints; any traces of cracks or leaking lubricant require replacement.

Question 2

What factors should you consider before starting the overhaul of front CV joints and CV joint boots showing signs of wear on Audi A4?

Accepted Answer

Wear of the CV joints in case the boots are torn, look before you leap at doing the overhaul, however, full rebuilt driveaxles are on exchange basis which save time and energy. Start by taking the driveaxle out of the car, clamping it in a vise that has soft jaws, and cutting away the outer joint boot that has clamps on it. Unscrew the boot, until the CV joint is exposed, wipe the excess grease off, and tap the joint off the end of the driveaxle with a hammer and a brass punch, but be careful not to strike any part of the inner race. Store circlip to driveaxle groove, thrust washer and dished washer then take off, observe their installations position. Remove the boot and clean the outer CV joint assembly, indicating the locations of the bearing cage, inner race and housing. Install the outer CV joint in a vise, take out the ball bearings one by one, and in case it is necessary, loosen the inner race by tapping. To detach the cage and inner race assembly, place the cage windows at the same level with ball grooves and clean up all components and check whether they are not damaged. Provided that the components can be serviced, get a boot replacement kit and grease all parts with CV joint grease and then re-assemble. Fit the inner race into the cage and align marks then insert the assembly into the housing. Install the balls, grease the joint using the inner race hole and stuff the joint. Clean the axleshaft and slide on the new clamp and boot, pouring up the rest of the grease into the boot. Fit a new circlip, making sure it clips into place and then fasten the boot with clamps and before replacing the driveaxle, make sure the joint moves freely. In the case of an inner CV joint, loosen the boot with the clamps and pull the boot away then record the association of the parts and then take away the axleshaft. Wash and wipe off all the parts, examine the wear, and change the joint when required. After making everything back together, place the housing on the shaft, lubricate the spider posts, and attach the rollers. With the grease applied, then install the boot and clamps and then ensure that the joint is free before the driveaxle is re-attached. In the case of triple-roller type joint, the same steps should be used to remove and replace components, making sure that there is appropriate alignment and lubrication during the process. In the case of the ball-and-cage type joint, pull off the inner joint by removing the boot cap, knock off the boot clamp and removing the snap-ring. Before installing the driveaxle, clean and wipe all parts and reassemble using grease and make sure the boot is well seated.
