Darkseid is on the right track check the ball studs that the torque/tierods snap on to, the ones that replace the upper deck. If the long ball studs are used they will rub on the belt. I have seen this before at the track check them out and see that you have short ball studs in the right locations, if not get a dremel and grind them down some.
