i finally received my rear inboard cv boot kit today, so i dug into replacing it. from what i had read, it was possible to remove the axles without taking the trailing arm off (which requires a special spanner socket). supposedly, if you unbolt the lower shock mounts, the trailing arms will drop far enough for the axles to clear the differential. i did this, and the right side (when seated) will come out, because it's shorter. however, my left side was torn - murphys law. because it's longer, there's too much bind in both cv joints to allow the trailing arm to drop far enough to remove the axle. i don't have the socket and won't step foot inside my closest can am dealer (that's another story) so i unbolted the diff. i also had to unbolt the caliper to allow the diff to move enough to get the axle out. now that i have the halfshaft off the bike and in the vise comes the 2nd mystery with the replacement. some people say there's a circlip that must be spread open to remove the plunge joint from the shaft, some say it's a locking ring and you must smack it to remove it. well, on the 08 renegade, it's a locking ring. came off after a couple whacks with a ballpeen hammer and a block of wood. removed damaged boot, cleaned out as much of the original grease as i could and put the new boot on, along with the new locking ring that came in the kit. for some reason, driving the plunge joint back on wasn't as easy as getting it off. took about 8 hard shots, broke a couple short 2X4s in the process! :banging: put the new grease in and used needle nose pliers to lock in the pita clamps then put it all back together. tomorrow i plan on cutting a few holes in the airbox lid and installing the frogzskin intake screens. not sure how i wanna block off the factory intake, but i'm sure i'll come up with something. :beer"
