Power Steering pump replacement

[4x4wannabe]

Hello everbody, my steering has been making lots of noise lately and my dad and I have concluded the power steering pump is bad Anyway im getting ready to go up to advance and get a new one so hopefully i can replace it tonight. My haynes book isn't to clear on bleeding the system after installing the new pump. Any suggestions on doing this so i wont screw anything in the new pump up? Also we have ran ps fluid in the truck since it was new. Should i switch over to atf when I change the pump?

The PS pump calls for Mercon V. When I replaced my rack and pinion, I had the wheels off the ground with the truck off. I poured ATF in the reservoir and let it bubble some of the air out itself. I'd pour more in when some of it ran down. After doing that, I'd start the truck (with the wheels off the ground still), and pour some ATF in. I'd then get in and turn the wheel lock-to-lock. I did that while having someone else pour ATF in the reservoir as it purged the air out.
