Noisy power steering pump

Noisy power steering pump
I recently replaced my power steering pump with a rebuilt from roversnorth. It has been in since 3rd week of October. I installed it using instructions from Rave CD. Used Rover fluid and added Lucas. Since day one when I first start the truck it whines slightly then gets quiet. As the engine warms it will start to whine again, I should add it never gets very loud and steering is always very easy. After engine is at full operating temp within about 10 mins later it will quiet down and no noise as long as I drive. It repeats this every time it has cooled all the way down. Are these pumps known for being noisy? How long will it keep doing this? Is it damaging the pump when it is whining? What causes the noise? Is it the fluid not flowing right that makes the noise? Is it possible it will leave me stranded one day? I know its alot of questions but it has been doing this so long I keep waiting for it to either stay quiet or break. Any input would be helpful......

Did you bleed all the air out of the steering box? A bit of noise on first start up in the winter is normal but only for a second. Are you losing fluid? Are there air bubbles in your fluid? It may be that the Lucas made your fluid too thick, you should not really need it, kind of a shame to add it to a nice synthetic fluid like the rover fluid.

Could just be the cold and the thicker fluid and maybe a little air in the system. As long as you have no leaks and no bubbles your system is tight. Keep an eye on the level and maybe try another fast bleed.
I replaced my pump with a used pump it sometimes gives me a groan for 1 second on really cold mornings then it is dead silent.

Yea I don't mind that little bit at start up. Mine does that exact same thing. If it was too thick why would it start to whine after warming up a bit? Oh almost forgot when it starts to whine when warming up if I turn the wheel to the right the pitch of the whine changes. But like I said after warmed up it quiets right down.
Also the lucas I added was not the thick stop leak. It was the conditioner.

I'm just guessing here that you may have a very small leak that lets in some air and then the bubble works its way out when the fluid gets hot. Or you can have a bubble in the system that still needs to be bled out. Did you change the o ring that goes into the high pressure fitting on the pump?

LOL!! On the shooting in the air!! The first time I bled it " I thought I could do this myself I don't need two people....So I loosened the screw, put my hose on it had it pointed in my pan no problem right? As soon as I turned the wheel that fluid was like old faithful---What a mess!!
Thank You for your help....I will try bleeding again when I put the new o-ring in
