Default Help with power steering pump.....86 K30

Hey guys,
I replaced my power steering pump last night because my old pump seemed to be worn out. The truck was very hard to turn and making it hard to drive.

I got the new pump in and while it steers better, it is still hard to steer. The truck isn't lifted and only has 33's on it so the steering geometry should be dead nuts on. I am thinking that there is air in the system since I had hoses disconnected.

Does anyone know the proper way to bleed the system? I get the basic idea but there are 3 hoses coming off the pump and I am not sure which hose to remove. Maybe I am just confused altogether, wouldn't surprise me if I was.

Any help/info on this would be much appreciated.

Thanx,

Sean

Generally all that needs to be done is fill the system to the proper level. Turn the steering wheel back and forth all the way. (lock to lock). Sometimes it will take only a minute, but I have had to let some sit over nite and repeat in the morning.

Is it squealing or noisy at all?

Yep fill it up to the proper level and keep turning it lock to lock until there no more bubbles come up to the top.

3 hoses? do you have hydro boost brakes? how do the brakes feel if it is hydro boost?

plus if you have them bleed them down. with the key off pump the brake pedal at least 5 times. that way you dump the air & fluid trapped in the accumulator. when you restart cycle pedal a couple times as well to get the fluid moving. hope you figure it out.

Hydroboost? I have heard that term before but I am not familiar with what it is. Sounds like that would clear up my confusion of why there were 3 hoses running out of my power steer pump.
I will try bleeding them down tomorrow as you said and see if that helps. I have turned my wheel lock to lock trying to bleed all I can and my power steering still sucks.

Thanx again,

Sean
