Thanks Mike the explanation of scrub angle makes a lot of sense. I've had this wheel/tire set up on the car for 20 years now though and I've never had a problem till the last year or so. I don't think I've put 10K on the car since the restoration and the suspension components were put on. It was aligned last year too.

Maybe tomorrow when it is nice out I'll get someone to drive it around while I look and listen.

Thanks for all the suggestions

Paul
