I have the same machine; and the same complaint. I never notice it until I ride in snow. It is horrible and frankly dangerous at speeds over about 10mph. Even in 4x4 it's supper squirrely. Constantly have to "saw" the wheel to try to keep it going straight. Did this since it was new. I never notice it on dirt trails. I believe I read on this forum somewhere that Polaris changed something in the '15 models so the front wheels engage sooner to reduce this issue.
