I have a 03 SP700 and at 11 hrs on the machine the front wheels strated locking in when it was in 2 wheel drive. Took it to the dealer and they tore it down to find the front drive shaft bent and front iner plastic housing broke, they fixed it. At 27 hours same thing. They told me that they talked to a technition from Polaris and it was from reving it high and spining the back wheel. I told them that was a lie because I have not done that. Can someone advise me on this issue?? They are fixing it again under warrenty.
