Power steering pump is whining and barfing

So the power steering pump is whining loudly. It started last week and I have been trying to keep an eye on it. I drove it to work and when I got to work I looked in the res and it was milky looking with air bubbles in it. It was also pushing fluid out through the reservoir.

In the put some stop leek in it a year or so ago because is was leaking. It stopped leaking and has been working fine for a year.

Any tips on replacement and bleeding the lines? If i put stop leak in it, should I flush the system or just bleed it?

I really just want to drive my forking X. It has been either in mod or repair mode for the last month. AAAAAAAARRGGHH!

Mine just took a dump a couple of weeks ago. I had a tech at work replace it and tighten up all the clamps on all the lines cause they do get loose and leak. He also flushed the system out.
It did push out the resevoir and get all milky looking too. I believe mine was slightly whining for about a year or so and then BAM!!..just like that it went out quick.

Recently I replaced the clamps with better ones (was leaking at the hose area) and replaced the fluid while at it.

Based on suggestions from others I rigged up a a hose to the thinner hose and ran it to another jug to collect the fluid. I then started the ignition and poured fluid into the reservoir to pump in new and out old. I just watched for color change to newer red ATF (I was using ATF for my fluid per manual).

Before you pour in fluid use your finger and from the bottom of the reservoir block the hole you created by pulling off the thinner hose (don't be a bone head like me and forget and have ATF running down the manifold) )

This won't solve an existing problem - but if foamy just from a leak and low fluid this will help replace fluid.

It is turning real smooth and it solved 2 wierd noises I had been hearring for a long long time wondering what they were.

One noise of course was the whine noise which I had checked fluid before and always looked good so I was afraid it was the transmission.

Two was a slight knocking type noise that I don't seem to hear anymore either...it was very faint noise but I could hear it....when the pump went out it sounded like a lower end knock and freaked me out even though the engine was running good.

That makes me feel tons better. I too have been hearing a knocking sound and just having replaced my timing and was thinking the worst. New pump should be here today.

the milky is likely an air leak, it says you have a bl so maybe the hose has come off the fittings. I replaced my overflow hoses with longer ones i made from autozone for a few bucks. Might be worth a shot while your at it. Its pretty simple. I did a mini write up in the body lift how to thread. Its was somewhere up in the teens of pages.

Do you think I'm ok to drive it home or should I have it towed to avoid damaging the PS gear box?

I parked mine at work and did not attempt to drive it at all...I personally would not drive it if you do not have to but I can't tell you if it will hurt anything else by doing so.

I pulled the old pump tonight. The new one goes in tomorrow.
Tips for removal:
1. Pull the battery.
2. Loosen the belt pulley nut while the belt is still on.
3. raise the X and pull the passenger side tire and pull the rubber back to see the pump.
4. siphon as must fluid out of the reservoir as possible and put a bucket under the X.

I'll report back when it is back in and working.
