Power Steering Pump....

Hello,
I've read a bunch of other posts in relation to the same problem I am having, which is that the pressure relief valve is getting stuck on my power steering pump, which has left the truck undriveable. It first happened about 4 months ago. I wasn't sure what the issue was at first, but I took the cap off the PSP and there was a bit of pressure there. I replaced the cap, started the truck and everything was back to normal. I've had no issues since and kind of forgot about the problem. On the weekend I parked the truck friday night, and didn't drive it until Sunday. After starting it, I noticed that I had no power steering or brakes again. I tried the cap trick, with no success. Monday I ordered a new power steering pump to be installed. I read a lot of posts regarding the same issue in the forums and that some people have cured this issue by doing a fluid flush. My concern is that if I am driving it and the valve becomes stuck leaving me with no power steering or brakes, I would be certain to be in a wreck. I have not had the valve apart to see how it functions so I am hoping someone can give me some feed back.

So my questions are:
1. If I start the truck and I have power steering and brakes (ie: Value is working properly), can it malfunction after I start driving?? Or once the fluid is circulating, it will stay (Im assuming) open and I wont have any problems??

2. Truck only has 90,000 KM is this typical this early? The pump shaft is not broken. Any other thoughts why the valve is not working? Is it possible there is debris in the system at only 90,000KM? (Unless an o-ring has fallen apart, but I dont have any leaks).

Thank you!
T

Mine did the same thing once ,fired it up and went to back out of garage and no brakes or power steering. I checked fluid, moved it back and forth still nothing, shut truck off and started again and everything was fine. I noticed a little twitch in the wheel when hitting the brakes while driving and then I did the flush and it's like new .Also around 97,000

I always have a twitch on the steering wheel when first applying the brakes and have flushed it.......I'm amazed theres not more wrecks with this scenario of both steering and brakes being linked to the same system.......you could possibly lose one and survive but both, lady luck has to be on your side if you lose both........

Titanite, What are you doing to resolve the issue. The PS Flush sounds like the consensus and the cheapest solution. IMO if the flush does not fix the issue, then the hydroboost would be my next guess, not the PS pump. I just replaced my high pressure PS line (leaking) yesterday, and while I was there I flushed the system. 94,500 miles. You won't believe the amount of crud that is in the system. I wounder if a inline filter can be installed?

Hello All,
I replaced the pump as I believe it was the culprit (well the pressure relief value), but you cant buy that separately. When the valve doesn't hang up I have no problems, but when it does, truck is not drivable. The flush might have worked, but when will it hang up again. I cant risk having this go wrong when driving. It was the more expensive fix, but worth the $200 and time to fix in my opinion.
