I have a noise in the right rear wheel area that I first thought was something in the tire but nothing was found. It has gotten louder and I am at loss to what is causing the noise. It sounds like a Thunk and doesnt do it every revolution of the wheel but it does do it quite often. I almost sounds like something is knocking on the fender down low. I had some friends listen and look at it and they thought it was a u joint. I checked the driveline u joint (2014 Champion IRS kit on my 2007 Goldwing) and found it was in fact failing so I replaced it. Noise is still there. I am wondering if the cv half shaft would make such a noise? I have about 30 thousand miles on the conversion. Any ideas? I am willing to check them all out. :0) Thanks!
