650 Rincon Grinding Noise - What's Going On?

Hello all, I have an '03 650 Rincon with about 450 miles on it. I mainly just do trail riding, but I have crossed a few water filled ditches over the life of the machine. So here's the problem, when I am turning and hit the rear brake, I get a very loud grinding noise from the rear of the machine. It doesn't do it when I'm going straight, just when I'm trying to turn, so I don't believe it is an actual brake problem. My guess is that I have something wrong in the rear differential or rear CV joints, but I thought I would get some advice here before I take it into the dealer.
Thanks in advance for your help!

Actually the rear brake on the Rincon is a disk brake mounted to the drive shaft. I read on another forum that there is some play between the disk and the drive shaft, and that this can cause the chatter when using the rear brake. Sure makes a loud chattering sound when I have the front wheels turned and apply the rear brake. Maybe it's not a problem?

I have heard of that problem and my buddy's 650 does it a lot. Check to see if you can wiggle the rear disc. If so, I have seen on RinconRiders.com that someone fixed it by tightening the rivets holding the disc. I think he used a punch and hammer. I don't believe there is any danger of it coming off. It just wiggles some. My 680 has not had this problem.
