Wheel Alignment

[Tonyx]

Front toe can't compensate trust angle - it will simply center itself with equal toe for individual wheel. With steering wheel off center, of course.

Crab down the road is usually a problem with misaligned/tilted front or rear subframe.

I stand corrected by vtl. Thrust angle needs to be set to zero and it's determined by rear toe only. Vehicle can still track straight but 'crab' down the road. If the car is still pulling(and not just "visual pulling" with offset steering wheel) then look at front caster or front tire swap as suggested earlier.
