I had good fan and zero cooling problems so I thought the steering box was leaking internally. Replaced it and still had hard steering at idle.
Bought a reman pump from mopar and it fixed it.
The fan will move slow. It only speeds up for certain things. If your concerned the fan isn't operating just pull the engine coolant connector with engine running. It should turn into a airplane.
Also if you got a pump from someone other than mopar it could still be the pump.
