As I accelerate thru 25-30 mph I hear what I can only describe as a yelp sound. The belt isn't too tight. When I back it out of the garage before I start the engine I don't hear any sound from the belt either. Get the yelp both accelerating and decelerating. Also, around 10 mph I hear a rubbing sound. Brake pads all look good. Half life left. When I installed new tires front and rear (Commander II's) the wheel bearings were all nice and smooth. I did work some grease into them. For those who saw my post on the Speedohealer (by Healtech) I removed it and the skip went away. Thanks Rick. As I'm writing this Blue Monkey Motorsports (where I bought it)has offered me a refund. Anyone know if the wheel bearings can be changed without that special tool that the book calls for? Yelping and rubbing is annoying. Oh, the belt is showing no sings of wear.
