2002 Taurus vibration

I have a 2002 Taurus SES with 80k on it that vibrates when turning to the right and when I hit a bump in the road. It doesn't vibrate turning to the left.I took it to the tire shop and had it checked out and tires balanced and it still does it. I took it back to the shop and they can't find anything wrong. They checked all bushing and rods ends. Any help would be appreciated.

Try rotating the tires.
