What could be causing this shaking of my car at this particular speed range? It is quite apparent in the steering wheel and the seat, occurs when I’m accelerating and decelerating, driving uphill and downhill. Remedies I have tried: new tires, rebalancing the tires, checking tires for too much run out, new shocks, replaced rear end assembly, replaced rear axle shaft, cv joints, and rear wheel bearings, replaced tie rod linkage, and had the flex discs checked for cracks.
My car is a 1985 Mercedes 300 TD wagon.
Thanks for your time. Hope I haven’t confused you.

If you feel this vibration in the steering wheel, I would suggest that you check items like ball joints and tie rod ends. Even the steering rack could be suspect on a 25 year old car. Basically, your entire front end (steering and suspension components) needs to be checked carefully.
