thanks everyone for the help. Big Jim, I was starting to wonder if 'fishtail' was correct. She said it acts like it's on ice or rain and the rear goes sideways. but on dry.
I may ask to go for a ride. I'm wondering if the thing is in 4wd. My wrangler makes that wacky movement when you make a turn on dry roads in 4wd. Not that it is something I do often. I'll be back......
