I'm new on this board and it is really cool, I also have a question.
I drive a 92 loyale wagon with 138,000 miles, Manual 4wd. I noticed a rattling noise coming from the rear driver’s side of the car. I took it to a shop and they said I needed new bushing on my crossmember where it connects into the frame. I had the bushings replaced as well as a worn bushing holding the rear diff. The rattling is still there. I can only hear it when driving under 40mph. I can't replicate the sound by jumping on the car or shaking any of the rear suspension or exhaust parts. I have also taken everything out the trunk and secret compartments in the back. Any ideas on what this rattle could be?
