I just purchased a new 2014 Teryx Camo- I hear a strange noise coming from the rear of the vehicle when it is under a slight load such as climbing a grade. The noise does not appear when revving it up in neutral, only when in gear under a load. The noise is a loud vibration type noise that sounds like washers rattling in a coffee can. Friends following me can hear the noise over the engine exhaust noise. The dealer tried to listen to it, but it is hard to duplicate it in the parking lot. He said it was normal. Anyone have any similar noises? Or did I just buy a lemon ?
