2007 660 Sport Edition, 135 hrs, 1350 miles.
Climbing a hill today and when we turned around to come back down, kept in 4-lo (locked)and it sounded like gears, or some kind of grinding going on. When taken out of 4-lo (unlocked), and when the BRAKE was applied the sound came on as if it were a gear trying to engage/diengage, from the rear end.
At the bottom of hill, placed back into 2-hi and it ran fine until we were going down a slight grade and when i applied the brakes, again, it sounded like a gear trying to engage, disengage.
Close inspection of brake and brackets and it's all tight.... Any suggestions, ideas????
Thanks

Simply change the rear set of brake pads. They get glazed over from constant use or forgetting that little pesky brake lever being left on. Seams lime I went through two sets a year with my old rhino.
Are we camping yet?

Yup, like Fasttrax says - rear brake pads. Use cheap pads and change them often (they will glaze over and cause that noise way before you will ever wear them out).

Brake noise on the drive shaft mounted disc brake is caused by dirt inbeded in the brake pads, you can call this glazeing or whatever.
The cure, if there is one is to clean the pads, you can do this with sand paper and a flat surface, move the pad in a figure 8 pattern untill the pad has a new looking clean surface. The ultimate cure is to change the method that you use to wash the machine. When you are on the left side of the machine with the power washer and blasting away on the skid plate in front of the wheel you are blowing all of the dirt into the caliper on the unit. The dirt and soap residue get into the pads and cause a glaze...if you want to call it that. Just don't do that and you will probably fix the problem.
Always test the brakes to be sure that it is not a more serious problem. When you hear the noise it is when the brake is lightly applied. If the brake is slowing the unit proportional to the pressure applied it is OK. The noise is the problem not the brake action. Cleaning the pads is cheaper than replaceing the pads, not blowing the pads full of dirt is even cheaper. Good luck and enjoy the ride!!
