Steering gear break in period?

No, there is definitely a dwell with the steering wheel strait, so it feels like manual steering once the car is moving at significant speed and turning along bends requires very minor steering input. Once there's significant turn to the wheel in either direction feeling is varied, with less assist than before, and it feels like a bump or uneven resistance to turning. After even more turning the wheel wants to walk all the way to lock. When stationary it's very minor due to the resistance in the wheels but while coasting at idle it will free wheel to lock and not return to center. It does this in either direction.
If I am understanding correctly, maybe you have a brake drag or a low tire pressure in the front. It is correct, you need to center your gear box from left to right or your steering system could over heat while on a long trip. Almost "0" pressure in system while at center. If you ever turn your wheel all the way left or right you will or should hear a whining sound, that is the pressure release valve bypassing the built up pressure of the fluid. By the way, that is how you blead the system after replacing parts.
