swapped the summer wheels out on the 7 after i was getting a whole bunch of noise from the rear end somewhere. The dealer said it was probably how much tread was on the tires and what not. It was winter and i didn't want to mess with it. Took a mini-trip this weekend & the noise was unbearable in the backseat. people were practically screaming to talk to each other. Jacked it up in the air & tried wobbling the each wheel & couldn't get any movement. I spun the drivers rear wheel and nothing. Spun the passenger rear wheel & i get this dragging sound. If it is the wheel bearing, it should be covered under one of my warranties. I figured i might as well do it since there is this emissions recall for it. Something about it not being able to pass e-check or something.
