Need Help

1993 400SEL vibrates above 40 mph. I have replaced all tires and still have the problem. Stirring wheel not shaking, but I can feel in the seats. I appreciate any/all suggestions.

Vibration is usually wheel balance or alignment

I would also check to make sure you don't have a bent wheel. Since it is not coming from the steering wheel I would check the rear wheels first. Usually a motion vibration such as you describe is transmitted to the steering wheel in the form of a lateral or vertical motion or a combination if there is more than one source of vibration.
