  Q: How to inspect the condition of CV Joint Boots and assess the general condition of the CV joints on Volkswagen Cabrio?

  A:

  The car being in the air with the jackstands in place, make the steering wheel go all the way and move the wheel slowly. Examine the state of the outer constant velocity (CV) joint rubber boots by squeezing the boots to open out the folds, checking them to see whether they are cracking, splitting or deteriorating which could also enable grease to leak out and cause water and grit to enter the joint. Check also security and condition of retaining clips, repeat also checking the inner CV joints when checking driveaxle condition. In case there is any damage or deterioration, then the boots must be changed. At the same time, check the general state of the CV joints by gripping the driveaxle and trying to rotate the wheel then do the same with the inner joint and trying to rotate the driveaxle. Whether it is a significant movement or not will show wear in the joints, wear in the driveaxle splines, or will show a loose driveaxle retaining nut.

  Q: How to remove and reassemble a CV Joint and CV Joint Boot on a driveaxle on Volkswagen Cabrio?

  A:

  Starting with, take out the driveaxle of the car and clamp it in a vise using soft jaws. Relax the two joint retaining clamps of the outer joints, cutting them off where needed. Slide the boot down the shaft to reveal the constant velocity (CV) joint and rub off excess grease. Tap the joint at the end of the driveaxle with a soft faced mallet, and then remove the snap-ring in the groove, the thrust washer and dished washer and record their position of installation. Remember to discard the boot, clean the outer CV joint assembly, labeling the relative positions of the bearing cage, inner race and housing. The outer CV joint can be attached in a vise and the ball bearings removed in a criss-cross pattern tapping the inner race where necessary. To take off the cage and inner race assembly, position the cage windows in line with the housing lands and swing out the inner race. Clean and then check any damage or wear, solvent test all parts, any parts that cannot be serviced, replace the whole CV joint assemblies. Provided that it is satisfactory, a boot replacement kit should be acquired and all parts coated with CV joint grease, and the process of reassembling it should be underway, by installing the inner race in the cage and aligning the marks. Installing inner race and cage assembly into the housing followed by putting the balls into the holes one after another. Insert the CV joint grease with wooden dowel pushing the grease up to the inner race hole. Wipe the end of the axleshaft, then insert the new clamp and boot and pour in the remaining grease in the kit into the boot. Lift protective tape off of splines on the driveaxle, slide dished washer and thrust washer on and attach a new snap-ring, and strike a joint on the driveaxle until firmly seated. Lay the boot over the joint, making sure that the lips of the boots are in the right place and put in place the large retaining clamp by tightening it with a special tool. Install the small retaining clamp in a similar manner, and in this case also be sure that the constant velocity joint moves freely before the driveaxle is reinstalled. In models which have automatic transaxles, there is no spare parts or dismantling information available and as such, consult a dealer in VW. In the case of manual transaxles, the inner CV joint will need a hydraulic press and special tools, which means that it is better to call upon a qualified repair shop.
