General Question about power steering

This isnt a Ford question, but I am hoping someone can shed some light. I also have a 2005 GMC Sierra 1500 Z71 and I was having problems with what I thought was the power steering pump. I replaced the pump and might steering wheel still turns really hard to the right, but is free to the left. I put the front end in the air and it turns like butter both ways until you put weight back on the front wheels then its hard to the right again, but not left. Bad gear box?

Forgive me for bringing GM into the Ford arena, but I dont want to join another Forum for such a general question. Mitch, be gentle....

My guess would be air in the line still.

I would tend to agree but it acts the same way now as it did before I replaced the pump. I didnt have any leaks, just hard to turn to the right.. So I dont think air is the culprit... Anyone else have input?

So back in August when you had the "slop" is it possible you over-tightened the gearbox and the bearings are now binding?

This is on my GMC Truck, not my Excursion. No adjusting on the GMC...

Okay - bearings in the gear box may be the culprit as you've got the same symptoms after a part replacement since you fully purged the lines of air after pump replacement. But then ultimately, this is a different vehicle than the Ford so my speculation is just that...a conclusion reached by conjecture not necessarily supported by fact. Is there a good Chevy Z71 forum with a bizarro-world like figure of Ford-insight such as commonly found here?

Not familiar with the system so I don't know... On some of the military diesel trucks if you install some of the hoses backwards it will only turn in one direction and in the other direction it will be extremely hard to turn... Have you had it apart recently?

I had the same problem with a 2004 Chevy Avalanche, it was the gear box.
