So my 13′ xp900 had a lot a squeaks and stuff. Which I don’t mind. But.. When I’m on a road where I can really pay attention I hear a weird noise from what sounds like the front end. It’s sounds kinda like a grinding noise. The problem is I have the alba pipe so it’s loud and I have a hard time figuring out what’s normal and what’s not. The only thing in the front end I can see MIGHT be bad is the diff. I’m not sure if it’s normal but my drive shafts have about 1/8" play up and down side to side. Is it normal for them to move at all?
