On my '53 3100, when I turn the wheel hard over, and I'm rollin forward at low speed, I sometimes get a noticeable knock. Repeats maybe about once per second till I back off of all-the-way-to-the-stop turning. Otherwise everything in the steering/driving category seems fine. Since I can't hang over the front end AND drive when it's happening - or get anyone else to do so - I'm at a loss.
