Welcome to 2CarPros.
If it is pulling to the right after the work you had done, I need you to safely lift the right front wheel off the ground and see if the wheel spins easily. Also, have a helper apply the brakes and release them to confirm the brake is working properly. If it is, do the same with the left side.
Here is why: Since you hit that hard, you may have damaged a wheel bearing or something related to the brakes. If the left front brake isn't working, it will pull to the right when you apply brakes. If the right side is stuck on, you may feel a slight pull to the right and a vibration from an overheating brake rotor. Here is a link that discusses a pull due to brake issues. Take a look through it. In addition to a brake issue, the link discusses steering and suspension concerns. Any of those things may have been damaged in the accident.
I hate to assume, but when the alignment and rack were done, the control arm and bushings, ball joints, tie rods, and all steering components should have been inspected. Confirm that was done.
Let me know if you have questions or need help. Also, let me know what you find.
