My '75 coupe seems to bounce a bit in a turn that is not smooth.  Any ideas what would cause this?  Could this be considered normal?

Have you done any work to the front end, trailing arms or suspension? Mine was an alignment issue after trailing arm replacing bushing and rebuilding front end. Had to align my vette using the string method, no one in town could align on there machine.

I've only had this car a little over a year.  I know the previous owner had quite a bit of work done on it, but I don't know about suspension work.

I would crawl her and visually inspect the sway bars and rest of the suspension. Check for lose nuts, worn bushing, rubber mounts, shocks and it could be tire related. Air pressure or broken belt in the tire. Age on tires they can break down. Just a few ideas but you should differently look over it before driving it to much more. If I can help just let me know. I am in Lexington down the road from Cana.
