The car is a 1989 300E with about 180,000 miles. When it runs over small
bumps on the road, it makes a rattle/knock sound. It is very annoying and a
little scary. I think it is coming mostly from the left (drivers) side of
I replaced a worn out drag link recently, and hoped that was the source of
the noise, but it wasn't. With the front end jacked-up, the front wheels
don't have any play in them when I try to wiggle them side-to-side or
up-and-down. While under the front end I replaced the steering damper too.
Everything got torqued properly.
Any suggestions on how to diagnose the source of the noise? Are there some
"bushings" that are known problems? How do you check them to see if they
are good/bad? Visual inspection?
