If I push the rear of my 91 side to side it makes a popping or clunking noise underneath like something is loose and hitting somewhere. I can't tell if it's from the track bar or control arms or axle??? Also it doesnt take much effort to shift it sideways.
It seems as if the body is shifting on the suspension but Im not sure...

Any ideas?

Thanks.

panhard is supposed to control lateral movement - have a look at that
