When I had the alignment done, three or four years ago, the tech told me he got a bit over one degree of positive caster, so it sounds like I'll be getting the tires off the ground to find how that feels. I'm not a front end tech and I appreciate the onfo about the tires raising the car on turns. That hadn't occurred to me but it makes sense. With the small positive castor the car supposedly has it seems I might be looking for some other issue.
