What could be causing my Audi 80 to vibrate during acceleration?

I recently noticed that my Audi 80 starts to vibrate when I accelerate. The vibration is most noticeable when I reach speeds above 40mph. Any ideas what could be causing this and how I can fix it?

It is possible that your tires are out of balance or have uneven wear. This can cause vibrations during acceleration. I suggest getting your tires inspected and possibly rotated or balanced.

Another potential cause could be a worn out suspension or steering components. These parts can cause vibrations when they become worn out and should be inspected by a mechanic. It's always better to address these issues sooner rather than later.
