There are very few reasons that can cause a Wrangler to "pull" left or right. Pull being the operative word. Is it actually pulling to the left or is the steering wheel off and when you center it the vehicle drives to the left?
1. Cross Camber being unequal due to bent inner C or steering knuckle, worn out ball joints, or improperly adjusted offset ball joints (used to correct for previously mentioned bent parts).
2. EXTREME differential in Cross Caster (again something is bent)
3. Something is dragging, brake, bad bearing (bad would be an understatement) , tire pressure (you already ruled that out), or radial pull (one tire having more drag usually a bad casing) Radial pull can be identified by swapping front tires left to right.
4. Rear tires can also cause a pull (tire pressure drastically different) to one side or the other but since you didn't mention having the pull before the work that was done I would rule that out.
