You mean the bolt to the body mount?

Is simple to eliminate those mounts as the culprit. Just crawl under and inspect the bushings then climb in and re-torque the bolts. Shouldn't take but a few minutes each.
Inspect your rear sway bar, end links, and shock mounts while you are under there.

My body mechanic, had to re-torque my bolts after 50 miles. Stopped the knocking noise.
