I replaced my power steering pump a few days ago. And have developed a chirp/squeal as the truck gets warmer, before changing the pump I'd get it on start up and then it would go away normally. Now i don't get any noise on start up but after driving it a few miles it starts doing it, and seems to get worse as i drive. Is it possible I pressed the pully onto the pump too far? There wasn't anything keeping me from pressing it on too far so I kinda just judged It from looking at where it was on the old pump

 

Where exactly is the noise coming from?

 

Definitely the belt/pully area, i can't pin point where it is exactly

 

Bump.. The sound goes away when I'm in driving, but as soon as i hit idle again it goes crazy possible I streached the belt?

 

Are you losing any coolant? Water pumps usually chirp and weep when going bad. Take the belt off and turn the water pump pulley by hand. Should be silky smooth turning. If chalky, replace. Also, if it's the belt, you can spray water on it and see if it quiets it...that would confirm it.
