Looking for advice to where i go from here!

I recently had to change my steering gear box because of the shaft breaking. Replace it and the pitman arm and drove the truck with no problems for a week. Next thing i know the truck didn't have powersteering or solid break pedal. I change the power steering pump (oreilys) and bled as instructed by the info i found on this site. The brakes are working and my power steering is around 50%. When the turning the wheel the truck seems to have power steering but doesn't at different rotation of the steering wheel. Is it possible i still could be air locked or is it time to change the brake booster?

Raise the front end and see if you can turn the wheels back and fourth by hand. If you can than you have power steering problems but if you cant then you probaly have bad axel joints or possiably bad ball joints.

After plenty of research and trouble shooting..... I determine i had a defective steering box. Pulled it all back down and replace it again. Everything is operating properly now. Thanks for the reply CHFORD !
