Something I didn't see in the responses was the reason that the car changes lanes when you hit a bump. Ready for it .............................a very common problem made much, much worse because your tie rods are now adjusted to different lengths on each side.. BUMP steer. When the suspension rises and falls , the tire/wheel assembly follows and arc. Iff the tie rod is effectively longer on one side and shorter on the other the front tires will follow different arcs. This is the same as turning the steering wheel to one side or another.
Refer to the FSM for basic dimensions and proper assembly procedures on doing front end/suspension repair.
