Hi, I have an '05 X-Trail SE and after getting off the highway the other day (drove for about an hour) we heard a fairly loud grinding noise coming from the middle/back of the vehicle. We thought at first it could just be some ice in the wheel wells but I took it out today (+5 degrees) and the noise is actually worse. Our local dealership is closed for another 4 days so I can't take it in...The noise is worse when braking and turning corners but it's also there when accelerating. Does anyone have an idea of what the problem could be? Thanks!
