Hey guys...just bought a 2012 570 and took it out for a drive today for the first time. It rode alright but have a rattle/crunchy/grinding noise that seems to be coming from the front driver side. Slow driving I don't hear it. About 10 mph it begins and gets louder as I go faster. Very distinct and loud at about 25mph. I have a 2012 XP 900 and bought the 570 for my son. Any ideas...I was thinking maybe a bearing. Emailed the former owner and he said he never heard it. Definitely something going on though. Thanks.
