Was riding the other day and noticed while in four wheel drive that only my left front was pulling, my right front was just "free" rolling. Any ideas as to what might cause this? Also I’m having key issues. My black key doesn’t want to work but once out of every 10 or so tries and my grey key is working about half the time. Went to my local dealer with my four wheeler on the trailer and expressed my concern to see what they thought, and they told me that it should be fine if the keys worked that morning. Any ideas on that issue also?
