I have a 1972 Hurst/Olds that seems to be vibrating on the drivers side left foot if I have my leg bent and left foot right in front of the drivers seat I feel a rather large vibration. No where else does the car seem to vibrate. Checked wheel balancing and bearings. All tires and wheels are identical. Any ideas where to check?

 

Body bushings?

 

Thanks Eric you are spot on with the body bushing. It looks like there are a total of 6 altogether. The one up front on my drivers side I can see looks split and definitely needs replacing. Can I just replace the one? or better in pairs the front two or all six of them? The other ones I can see look good. I notice people say it may add a little extra height the newer ones.

 

In order to change one the others need to be loosened, might as well do them all. You can buy a complete kit, they aren't very expensive. They can be a pain in the butt depending on what part of the country your car resides in due to rust and corrosion.
