My 32k mi one has developed a terrible squeak from the left rear wheel. I pulled wheel and see nothing obvious. The noise occurs at every bump and doesn't change with speed or brakes or turns. I can reproduce by pushing down on left rear bumper. I have put up on jack stand and no play in wheel left to right or top to bottom. Replaced pads/rotors a month or two ago and all that looks good. Disconnected left rear end link and still there. Put jack under left rear arm and pulled tire. Pushing on bumper the sound seems to come from the top of the strut. I pulled strut today and looks ok but there is some orange staining at the top of the dust boot up near mount. Planned to take apart strut but got wrong spring compression kit from Advance Auto Parts. Returned and got right kit but will have to wait till tomorrow as its dark. Thinking of just ordering a new mount kit and see if that does it. If not then new struts. What's killing me is I have only 32k mi.
