Anyone out there knowledgeable re: suspension wear & alignment?
I had the wheels aligned 20 yrs. ago after I first installed radials. The car has always tracked/steered straight ever since.  I used to rotate tires, but finally realized the futility of extending tread life on tires that would be far out-of-date before the tread was worn enough to require replacement (not to mention the labor/grief involved). Anyway, since recently overhauling the brakes necessitated removing all 4 of my 11 yr. old Michelins, I took the opportunity to swap the fronts to the rear.  The rear tires were evenly worn (but hardly), while the outside tread on the fronts was nearly gone.  While I likely still wouldn’t want to mess with the alignment on a car that tracks so straight, I have to wonder if excessive positive camber (?) might be a sign of normal ball joint wear?
