think they all pull left a little, even with 4 wheel alignment. think theres some quote on here from powerstation saying off all the 100s theyve done they pull left a little. only way to rectify causes wheel scrub.
mine pulls left, but im a bit beer belly impaired. if someone sits in the passenger seat it evens it out. also macpherson struts are prone to this iirc, shorter driveshaft on left will cause torque steer to that side. knakcered front diffs can do same.
but i think its just a 'thing', but im sure sure some more knowledgeable person will be along ...
