Since changing my exhaust hangers I have now developed a squeaking noise in the drivers rear. I thought it may be the hatch but as I am driving down the street I open my door and I can hear it coming out from the drivers rear tire area I think it may be the exhaust rattling around but I can not tell. It does not do it at all speeds and does not do it till you get moving a bit down the road say 25-35 mph and then continues till about 60-70 mph and then goes away. I would think if it was something mechanical in the rear end then it would do it at all speeds but does not. Any thoughts would be much appreciated as it is driving me crazy trying to find it
