Hydro boost ps pump

[1ton-o-fun]

My C3500 power steering pump has whined since I got it. Fluid is full, but the whining is getting worse and now with some of the noises, the brake pedal fluctuates Red Head and Blue Top websites aren't ultra detailed, and rebuilding mine seems to cost more than getting one of theirs.

Just seeing what's out there. Thanks!

I haven't looked at their sites for pumps, but I'd assume that since they do rebuilds that the cost for theirs includes a core, which you'd get back once you shipped yours to them.

There's also that place in AZ that was mentioned a week or so ago.

Call them Tuesday?

Turn One in MI can also handle a pump rebuild.

PS whine you say? That's how mine failed!...on my way to the landfill with like 3,000 lbs rock and busted concrete.

The shaft on the pump broke... actually seemed like I found some forums on the later trucks also doing this.

I'd say it's time to replace it, unless you feel like rebuilding it yourself. Don't want to have brake and power steering assist gone on you. I replaced mine with the local parts store, and it's working okay.


I think think there's a popular swap from the GMT 900 trucks? I've seen it here, not sure if that's for the 1500s, maybe the brake booster? Can't remember at the moment? Lol

It's been a few weeks since I checked Redhead and Blue Top's websites. Iirc, one didn't even mention the 3500 hydro boost and the other seemed to want to "build" (add a couple of holes for lines?) a pump out of a standard pump.
I don't know my arse from a hole in the ground, but my pump is correct for my truck. I'd like to keep it that way. I will hit up a couple of yards to see if I can find a 3500 in the meantime.

Are they actually different? I've never wondered that.


On my GMT 800 1500 truck when I got a replacement PS pump, the local parts store must have given me a hydroboost PS, because it had that extra return nipple. At the time I did not know until it was already installed. I wound up hooking up a piece of hose with a plug and hose clamps.

Eventually I got the PS pump warrantied, but I think I ran it like that for like 1.5 years.

I think the valving and reservoir is the only difference. I wouldn't trust a parts store pump, at this point for me it's either T1, Redhead, Bluetop, or PSC. I'm done with junk.

Yeah, it's scary enough to lose power steering on a bigger vehicle, but brakes
too? No thanks!

That's why you have 2 feet. The Blues Brothers reference appears to not be readily available sadly.

I beleive you're supposed to have enough pressure for one (maybe two) brake applications if the pump goes out.... that's the cylinder that sticks out on the Hydroboost unit.
