1989 300te....I get clunking in the front end over small bumps, uneven roads. New front struts did not change the problem. However, the mechanic did NOT put in new upper strut bearing (is that what they are called?). I can see cracks in the rubber of the upper strut thing as viewed looking down at it in the engine compartment. As you bounce on the bumper, the crack will open slightly...no clunking.
Under the car, I was playing with the sway bar, grabbing it, jerking on it. It is 'loose' in the rubber mounts that connect it to the body (not the wheel assembly). The rubber mounts do not close tightly on the sway bar, about 1/16" - 1/8" space around the bar. Is that 'normal'? Are the sway bars supposed to be 'captured' by the rubber mounts, or left to have some play?
