My cars steering is stiff and the steering wheel doesn't return to it's position after turning. I just had the power steering pump replaced and that didn't fix the problem.
My car has 101000 miles.
My car has an automatic transmission.
Improper vehicle alignment, underinflated tires, and steering linkage defects including mechanical faults in the rack and pinion unit, can all cause hard steering and poor return of the wheel. The pressure line from the pump assembly could have a restriction and that would cause hard steering. Of course, double check pump drive belt tension just in case the issue is a poorly driven pump. Also, you should check the idle-up function for power steering. If that sensor system is not functioning, it could cause hard steering but would not be a cause of the poor wheel return.
