I have a 2004 polaris 330 magnum 4x4. Its making a whining noise in high gear. It doesnt do it in reverse or low. It is real loud going slow and the faster you go the higher pitch the sound. Checked the belt and it looked fine. I also checked the rear end fluid and it was alright. There is no way to check the front in fluid. Someone mentioned the clutch but any information would be appreciated. thanks
