The body mount under the driver's footwell in my LC is loose, i can hear and feel a clunk when I'm going around corners and it feels looser than the rest of the body mounts. I tried using a wrench on the first nut (the one closest to the bushing) and tightening the bolt from the top (under the plastic plug beneath the carpet) and the i got the bolt tight but the mount is still loose and clunking. What is the proper procedure to get a body mount tight on an 80?
