Need to check ball joints, tie rod ends and stabilizer end links.
Thank you. I was also told it could be a bad tire by my mechanic who called me just now from Greece. Nice of him to call but he certainly can't help.
A bad tire can make a lot of vibration but it will usually only pull in one direction...not back and forth as you described. Worth checking them though.
I just bought new tites. Turns out that was the problem. And a much needed alignment. Thank you for taking the time to respond. I really appreciate it.
