The Factory Tollerance is 20 lb. difference from side to side
without drivers weight. Since the car did not pull prior to you
doing the work, I would guess it is the Corner Balance. If you
also replaced tires at the same time the work was done you
could have a radial tire pull. This can be checked by rotating the
tires side to side, on just the front tires. The car sould pull the
other direction or even track straight. Are the tires directional?
Try this anyway to prove it is the Corner Balance. No Alignment
on the planet can correct a bad corner balance.
I don't think I would mess with the ride height adjusment
yourself, any change in ride height will effect the toe adjustment
which will cause rapid tire wear. Check the tires first and if it isn't
a radial tire pull, take it back to your tech and have him recheck
the Corner Balance.
Hope this Helps,
