My 650 brute force the four wheel drive is poping, when put in 4x4. But when in 2 wheeldrive it will make you turn even though you do want to and no poping. Someone said CV joint, I havent taken them out yet but they look fine in. I figured I would ask if anyone knew what it sounds like? Please HELP!!

 

First of all I'm new to this site and dont't know if you got the problem fixed or not.I had the same problem with mine and found out that I had busted the ears off of the main shaft in the front diff.Didn't know much about fixing it myself but ordered the parts off the internet and tore it apart and found it was a simple thing to fix.
