My car needed a front end alignment as it pulled a bit to the left and felt unstable at "higher" freeway speeds (I usually drive 70mph at 4,000 rpm). I read up on the subject and was impressed with this editorial, which was written for the 1800 series:

According to the author, going from negative to positive caster improves high speed stability. I went to my front end alignment place and they gave me 0.5% negative camber (as requested) and a toe-in as close to zero as possible, also as requested. But the caster is -1.89 degrees on the left and -0.39 degrees on the right, and according to the mechanic there's no way on the PV544 to adjust the caster.
My question is, is that true or how would caster be adjusted on our humpback Volvos?
