Car-1984 300DT.
Ive been having a vibration that makes an appearance when I am accelerating full throttle, from either a stop, or when speeding up, and once I am at highway speeds above 75-80MPH, it becomes a constant vibratiion, that will only reduce to barely noticable levels if I fall back down to under 75MPH or so....

In preparation to determine the cause, I had all 4 wheels balanced, and aligned. Vibration is still present. The front end is new and no components show wear that might encourage a vibration. The rear suspension only has new shocks, the rest of it is original with 184K miles of wear and tear....

I have suspected that the vibration is either the result of worn drivetrain components, or worn rear suspension components. However, an examination of the drive shaft shows that all things are in proper condition..

So my question is what do I need to look for within the rear suspension to determine if anything there may be causing the vibration? What rear susp. components will cause vibration if worn?

Any advice highly appreciated.

Happy Motoring!
