Hard pull to left
 

I'm getting a hard pull to the left that is particularly noticeable under acceleration. I recently had the shocks and struts replaced, and the tech also got it into spec on an alignment. The pull was there before the work, anyway. It mostly goes straight when not under acceleration. Any ideas what's causing this? Nothing else seems to be noisy, creaky or otherwise sloppy. Tires?

Mine used to do the same they advised me to replace the inner and outer tie rods, could also be the control arm.

Had an older Lexus that was doing that. The left front, lower control arm bushings, were totally shot.
