Update: I drove the car this evening. The box felt tight, but the steering effort was very light. After a few minutes of driving back and forth between two streets the steering started acting funny. I drove the car back home and discovered that the fluid was overheated. The pump I am using is out of a 99 Durango. I think the pressure is too high for the new box. I am in the process of adjusting the pump pressure. Hopefully this fixes the overheating and light steering effort.
