I recently reinstalled my PS pump along with new hoses. Since the front of my car was already up on jackstands, I filled the reservoir and turned the wheel lock to lock dozens of times to purge the air. I did this with the engine running and not running. Now when driving, if I turn the wheel all the way to the left or right while the car is either stopped or creeping very slowly, it squeals and is hard to turn and feels like it is grabbing. When driving faster than about 10mph everything works fine. Will air in the system cause this? It was fine before I took the pump off and put it back on. Any ideas?
