On cars with front wheel drive, the drive wheels must also be able to turn for steering. The drive axles are equipped at each end with constant velocity (CV) joints which allow power to be continuously delivered to the drive wheels-even when all the connections are not precisely straight. The CV joint is similar to older-type universal joints in function, but it operates much more smoothly at more radical drive axle angles.
 The inner CV joints attach to the transaxle drive flanges, while the outer CV joints are equipped with splined stub axles which engage the splines of the wheel hubs and are secured by the large nut. Each joint is packed with a special molybdenum disulfide grease and completely sealed by a rubber boot. Although some inspection of the CV joints and even replacement of the inner joints are possible while the drive axles are installed, complete inspection and thorough lubrication of the joints requires that the drive axles be removed from the car.
A torn or ripped CV boot can destroy the CV joint in a matter of days, especially if the weather is wet. It is a waste of money to replace the CV boot if the CV joint is already damaged.

The remanufacturing process is complex, but proven. First, all shafts are meticulously inspected. To ensure vibration-free performance, any shaft that is not straight or that has damaged splines is thrown out.
Next all threads are chased and seal surfaces machined and polished for easier installation and longer seal life. Outer and inner constant velocity joints are remanufactured to ensure quality and performance. All new metal slingers and dust shields are used to keep sealing surfaces clean, along with new ABS Rings for trouble-free anti-lock operation.
Finally, all parts are carefully reassembled using specially formulated, high temperature, extreme pressure moly lubricants. New, premium grade boots and stainless steel boot clamps are then installed in addition to new nuts on specific applications as needed.
At Clutch Mart, we recommend the use of high quality Remanufactured CV Axles. Upon customer request, we will install a brand new CV Axle.
We offer same day service on most CV Axle replacements.
