It could be tires, depending on what type of tire you have you will get a little ground noise from the tread on the offroad tires. This is just a guess on my part but Ive owed a few offroad vehicles and different tires do different things at the last few revolutions before stopping. Try having them spin balanced and rotated, my Hummers new and I want to get the tires rebalanced, I dont think the manufacturer does good with the Firestone 285 tires.
