Did you see the camber settings? If he was unable to set camber enough to meet spec, you could have bent parts. However,if you have a camgear power steering rack, there is an adjuistment of the power assist which can cause a bad pull. Take the ps belt off and go for a drive. Beware of extra effort, but if the pull is gone, or possibly moved to the other direction because it was aligned to compensate, the spool needs to be centered.

There is a cap on the bottom of the rack, opposite where the steering column enters, with two 13mm bolts holding it on. Remove the cap, watch for a sleeve which may or may not be loose. If the sleeve slips down, you need to hold it in place with a couple of washers and bolts so it cannot move. There is a 16 mm nut on the end of the shaft, locked with a metal washer. Remove the bolt and washer, and there is a sleeve with one notch on the end of it. By rotating that sleeve, you move the valve up and down.. It is easiest with two people, but start the car,turn the steering wheel both directions, and move the sleeve up or down until the assist is the same both directions. Relock the nut, using a new washer if the tabs are broken off, and then figure out whether the rack boot is open on the left side. In cold territory, water goes in the cracked boot, runs down and freezes around the lock nut, and when you turn the steering wheel you loosen it.
