Sounds like you could have a differential issue if you heard a pop noise. Lift the front end and spin a tire, the front wheels should move seperate directions. The rinny has a torsen differential which is great for sporty riding but sucky for some thick mud...(its been so long since I messed with my beast so I'm having issues remembering if the diff stays engaged all the time....) I'm off my game a little lately with the mechanical stuff, and I haven't had any booze yet, so I could be loosing my mind. I'd hang in there until one of these tech savy guru's chime in, or I start hittin the bottle and I start to remember crap again!
