my s10 leans to the right......

here lately i have noticed that my truck always leans to the right (passenger side) tuckin more rim on the right then the left no matter what height i am at whether its laid out or lifted up. I have 2 valves run on each corner,no sway bar. Could it possibly be because i havent had my alignment done since its been bagged (possibly one wheel has more camber then the other) . I never really noticed til about a month ago right after i pulled the sway bar,may have been doing this even before then i just really started to notice here lately. Since i have 4 valves up front it shouldnt be the air going fr9om one corner to the other right?? Someone who knows what it might be let me know.
