Just wanted to let everyone know a fix I found recently. I had a thumping noise going over bumps that sounded like it was coming from the rear of the car. I searched the forums and could not find a fix. A few days ago I had some time to just get a flashlight and look for anything that may be loose under the car. I believe I found it. It apprears that the Park brake cable rides along the driver's side just behind the rocker panel. There is an adjusting knuckle just under the driver's door. It has padding on it but when the brake is disengaged, it tends to bounce and "thump" on the floorpan. I put a "loose" zip tie around the cable and the brake lines to keep it from moving too much. Be sure not to pull it too tight as to not damage the brake lines. Problem solved. No more thumping. Just thought I would pass it along.
