My '89 300TE makes a buzzing noise from somewhere near the rear
susension whenever I go over dips or rises in the road. I never
noticed the noise prior to replacing the hydraulic accumulators, but I
did that soon after buying the car with 180,000 miles on it, so I
can't be sure the noise wasn't there before the accumulators were
Anyone know what this is? Could it be the level adjuster? possibly
the CV joints or differential? Some other part that rubs against
something and vibrates? It sounds like it could be a noisy electric
pump or something, but I can't tell - I haven't figured out how to
pinpoint where the noise is coming from since the car has to be moving
to cause the symptom.
Thanks in advance for any insight.
