How do you replace the inner cv joint or boot on an ATV?

The inner CV joint is fairly simple to remove. First you'll want to remove the clamps from the boot (you'll want to buy the additional clamp kit for $2). Being careful not to puncture the boot you can pry up on the tabs that hold the band in place or just cut by putting a screwdriver under them and prying up to give you enough room to get the metal snips under them. Once the boot is free slide it back toward the outer CV joint to expose the inner components. If you run your finger up one of the ball track you'll find a large retaining clip that goes around the inside of the joint just above the ball tracks. Remove the clip by getting behind it with a small screwdriver or utility knife. Once this clip is removed the inner cage, race, balls & shaft will come out all together (wrap your hand around this to prevent the balls from falling out all over the place). On most vehicles you'll find a retaining clip on the back of the shaft, remove this with retaining clip pliers or a large screw driver to spread the clip open. On some Polaris and Bombardier models the clip is recessed into the race on the side facing toward the outer CV joint. These should be spread open and then tap on the race to allow for removal. Once this is removed you'll be able to remove the cage, race, & balls all together at one time. Now your ready to install it on your new half shaft.Make sure the boot goes on first. Then place the cage, race & balls assembly on the shaft making sure that the tapered side of the cage and the recessed side of the race are facing toward the outer CV joint. Install the clip to hold it onto the shaft (unless you have the recessed type this will already be in the race. Then fill the inner CV joint housing half way with grease and place it over the cage, race, & balls. Then reinstall the large clip. Now put the remaining grease on top of the bearing and pull the boot down and install the large clamp. Then take a screw driver and place it in between the small part of the boot and the shaft and push the inner CV joint in all the way until it bottoms out. Then pull it back halfway (or to the mid range of the inner CV joint) and remove the screw driver and install the small clamp. Your now ready to install the axle back in the vehicle.
