Very interesting read guys. I have not really had any CV boot issues with my X4 since I got it. I did have a pinhole in the right rear outside boot last fall but I know that was because if I was being stupid and playing around on a 50-inch Trail and a stick or something poked it. I could not find a boot anywhere and I was on vacation that week and had more riding planned so I drove to Rocky Mountain ATV and bought a whole axle due to it being an emergency situation. My kind of emergency though LOL. Yesterday though I went over the mountain to Fillmore to visit my mom and on the way home the rear right inner CV boot started leaking. Bummer! I'm down for a minute. I don't know how it happened I was just about a fourth with the way back over the mountain when I stopped to get a bottle of water out of the cooler and maybe an adult beverage. LOL. When I looked down and saw the grease had been splattering. This axle is less than a year old. It being the one I changed out last fall. The front two axles and the rear driver side or all original with original boots never had an issue. I find it very weird that this one was so little time on it gave out. I hope this isn't due to the new 2-inch lift I just installed but I have not heard of anybody else having axle issues with any other 2 inch lift. I just got it back from the car wash so I haven't looked at it close to see how bad the tear is or if it's just a little hole or what. It really doesn't matter though it has to be fixed. Now I have to decide to go with an oem boot or aftermarket. I also need to buy the tool for the clamps since I have never replaced a boot yet but I still have the axle I pulled out last year that needs the new outside boot changed. So I'm going to order both Boots the inside and outside and fix both so that I have an extra axle sitting ready. I am just hoping that I will not need to do it again anytime soon.
