swap your front tires left to right and drive! bet it will drift the other direction!

edit ok just saw, sorry didn't see you tried it already!

what's the specs?

sometimes when you tighten a ball joint or tie rod with the knuckle turned it may try and go back to that position!

Are the upper bearings noisey? Any abnormal noises?

Also maybe check your axles to be sure they are fully seated...

Did you do any transmission work?
