My son has my car away at college. He said on the way down it started really pulling to the right and then driving real rough, kind of bouncy.

There isn't a jag dealership where he goes to school the closet one is a couple hundred miles away.

My first thought was a frozen caliper and I was going to go down there to change the brakes until he said it was bouncy when he started it without moving it which sound more like a broken motor mount.

I'm not so sure with that car does that seem right? He says it pulls to the left, very rough riding, but it's not making any noise like you think it would if it was brakes nor is the wheel hub hot to the touch. He's an engineering student but not much of a mechanic yet...

I'd really appreciate any help with this.
