Transmission may be to the front wheels through two axle shafts, in which the inner ends are affixed to the transaxle and directly splayed to the side gears of the differential. The outer ends are splined to the front hubs and fastened with a large nut; the left side axle shaft is shorter while that on the right side is longer and provided with an intermediate shaft carried by a bearing. The inner ends of the axle shafts are enabled with sliding constant velocity joints where they can rotate in angular motion; axial motion is also possible where the axle shaft moves with the wheel; a tripod bearing and a joint tulip where the joint slides in and out. Boot joints can be unbolted and are easily downloadable in the event that a boot is rendered useless, however, in case of damage of the parts, it comes as a complete unit that needs to be replaced. Each outer joint is made up of a ball bearing between an inner and outer race where the former can move in one plane angularly but cannot move axially. It is also good that the boots of such joints should be checked for any signs of damages or leaking lubricants because as much as possible CV joint boots when they are torn should be replaced promptly because they compromise the joints section. Replacing boots call for the demand of axle shaft. Signs that may indicate a car's CV joints are worn or damaged include leaks in the lubricants, noises in the form of clicking sounds when the car is turning and clunks that occur when accelerating after coasting, vibrating at high speeds. To check for wear, one has to pick an axle at a time and move it from side to side as much as possible while holding the CV joint housings with the other hand, to feel for loose splines, or sloppy joints, and at the same time, one should look at the axle shaft shafts to determine if they are cracked, dented or distorted.
