Power steering pumps are considered consumable. That's why steering gear rebuilders recommend a power steering filter. It's possible your previous pump has deposited debris into your steering box.

What kind of noise is it making?
Steering pump wine?
Grinding from the steering column?
Squeaking from the column?
Why did you replace the pump?
Why did you replace the column?
What kind of column is it?
What kind of pump is it?
What else has been done to the Bronco?
What size tires?
What size wheels and what offset?
Any suspension lift?
Any modifications to the steering linkage?

These are just some of the questions you need to answer to give us a little better chance of diagnosing.

Off hand, the first thing I would suspect is that there is still air in the hydraulic system. When you put the new pump on, and presumably new fluid, did you raise the tires off the ground even slightly, and turn the steering wheel back-and-forth 50 or 100 times?
Yes, the instructions say you should be able to turn it left and right perhaps 10 times. But most of us have found it takes 100 or more.
