Steering wheel pulls to left when braking and tires start squealing

Hi, I just had rack and pinion tie rod ends and alignment done. Now three days later hit a pothole and the steering wheel was turned to two o'clock position and now when I hit the brakes the steering wheel spins to the left at eleven o'clock position. It stays there and the wheels start squealing. Then when I stop and spin the wheel to the right then to the left and back strait it is fine, until I brake hard or back up all the way to the right then it goes back to the eleven o'clock position.
