This RZR is the first thing I have ever had with CV joints, so I am not sure how to tell when or if there bad. Its a standard RZR stock other then tires. 600 hard miles. And I picked up a clicking noise in the right front the other day, appears 4x4 works fine, and the noise comes and goes, maybe does it more when turning. i checked the CV boot its good, and I gave it the ol yank, pull, tug, twist, test, and it appears fine. is there anyway to tell if you have a bad cv, will it even have slop in it? My buddies all tell me its the cv for sure, I was just thinking it would have some slop in it if it were bad. The wheel hub/ bearings all appear fine, and spin freely.
