I purchased a used 93 with 147K last Dec. It now has about 157K on it. Thought I'd respond to your post because my front end was just checked over by a very reputable shop. They replaced the left inner tie rod end and gave the steering and suspension a clean bill of health. However, when I spoke to the mechanic he indicated that he thought the brake hardware needed replacement. I note that the invoice reads " Note: Calipers rattling". Since the inner tie rod was replaced, I have recently replaced the front hardware, but I failed to check out the pads and I wonder if the pads(on the car from the PO) have too much play between the slots and the pins and maybe that's the problem. The rattling over bumps is still there.
If you find out anything, pass it on in this post. You might check you hardware, however.
