did they put it on the alignment rack? did they give you a print out that shows everything within spec? are you sure that its an actual pull to the right and not just a crooked steering wheel? if you paid for an alignment and it still pulls, go back and b!tch, if its a reputable place they'll re-do it, make sure you get a print out......your best bet is to take it to a ford dealer, they know what to look for ie worn ball joints, bushings etc.
