lift, big tires, hows your alignment?

[95f150]

Hey fellas,
My 07 ctd with 6"bds lift and 37x1350 toyo's are getting horrible wear on front tires. Wearing bad on inside. Seems to be negative camber. Standing in front of truck from distance back tires look like they are leaning in abit on the top. Alignment shop says they are on spec, seems bs to me? These trucks a pain to align? Are they just an eccentric bushing above the ball joint?

Also on another topic, hows everyones trac bar? I get a poping noise once in awhile turning at low speeds and climb underneath and can tighten the nut on the trac bar on the frame side 1/2 turn or so everytime.
