Sounds like you may have dirty fluid or a cracked sprague carrier. Start by changing the fluid. Make sure you use the proper polaris brand demand drive fluid. If you still have issues after that, you will need to take the diff apart and look at the sprague cage. Look for and cracks or even completely broken. If it is cracked or broken, you will need to replace it. I would normally suggest installing the billet aluminum cage from superatv, but unfortunately they do not fit the 2005 models. Your next option is to get the john deere parts, they are normally cheaper than polaris parts. Here are a couple threads for those john deere parts. I have also included a video that will help you through the process of rebuilding the diff.
