I bought a 1988 535 on the cheap. It had been in storage for three years and not ran. When I drive it I can't hep but smile. But I have one niggle little thing I am trying to decide if it is a problem or not. When I back out of the drive to leave for work first thing in morning it seems to feel like the whole back end shifts or is loose. However, if I go really slow and at a shallow angel this does not happen. I have been told it might be subframe bushings. I have read on this and inspected them the best I can. They appear intact and in decent condtion. Is there a way to know for sure if it is the bushing are not? I would rather spend the money that this repair would cost on other items like struts and things.
