I heard somebody else say that. I don't think its the axle. One of ours had the stock axles clicking so they grabbed a Rhino before putting it back in the barn...and still clicked. The Talon does the same thing. Stock axles...aftermarket...no difference. The machines that click...just keep clicking no matter what you put in there.So a few weeks ago on the RMAX FB group there was a guy with an RMAX4 that had just installed Rhino 2.0 axles and was having a CV knocking on his rear passenger side. One other person also chimed in with a video of their Rhino 2.0 doing the same thing. I had chimed in on that post saying that I had just installed them without any knocking issues. I would put a link to that video but it was a FB upload not a Youtube so I couldn't figure a way to do it. But three rides after my installation I am now having the same issue on my drivers side rear axle. I already changed the passenger side twice because the first one I put in had a hole in the inner boot right out of the box. SuperATV was awesome and warrantied it right away but now this on the drivers side. I am tired of changing axles and not being able to ride. I haven't contacted them on this one yet due to my work schedule lately but here is a video of me going down my street. You can hear it distinctly though. I'm not sure if they had received a bad batch or what but so far I am not impressed with these axles.
One of my buddies in the shop says the diff or hubs just don't like the angle. We haven't narrowed it down exactly yet, but stock and aftermarket can do it.
I think its something in the trans. Maybe the input bearing...or could be a hub bearing. We can't seem to recreate it with stock or our axles when its off the ground up on a lift.
