During two seperate occassion at about 50-60 mph and only during a right-hand sweeper, I've had the steering-wheel shimmy/shudder until I straightened out.

It doesn't do it at speeds under 50mph, or even during right-hand turns at 25-30 mph, or even during a panic-stop.

Any ideas/areas to check ?

TIA,
