It seems I am always replacing either struts or mounts or both on my 1991 Buick Regal. I am the second owner . It only has 185,000 K on itand it goes through the struts etc. like crazy. I am guessing the quality of the parts being used sucks. No wonder Monroe doesn't guarantee their product any more for a year cause god damn it they wear fast. Just a rant I guess. The rear left is bottoming out now and I suspect the strut is shot.
