Repairing Your Car: The CV puller is a drive shaft puller and constant velocity joint remover, which allows you to press clamps onto the drive shaft boot collars and reassemble the front half shaft. 2. Dimensions of the CVJ Axle Remover: The overall dimensions of the drive shaft separator tool are 9.61 inches x 5.75 inches (24.4 cm x 14.6 cm), and the maximum diameter of the CV joint is 3.8 inches (95 mm). 3. Fits Most Vehicles: Includes 9 holes for full adjustment to joint assemblies of varying lengths in most cars, fits most vehicles equipped with constant velocity universal joints. 4.
