In my case, I had a bad rattling sound from the front when driving on washboard-type road bumps. Combine that with loose steering, and I initially thought that the steering coupler was the cause of the noise. After replacing the worn coupler, the steering tightened but the rattle still persisted. With my car jacked up, it was easy to see the loose subframe mounts as shown in my first photo.

I haven't driven the car yet, but I am anticipating a quiet and much improved ride.

Update: Oh yes!...very much improved. I now feel like I'm in contact with the road, and not just bouncing above it. Gonna check the rears again closely, they're probably due as well.
