Power Steering Pump Whine

[RICH17]

So now that the Lumina has exhaust and is pretty quiet all I hear now is the PS pump whining like a bitch. She a rebuilt Napa unit rom about a year ago and the fluid is full. She whines so bad you would think I had a whipple on there. Any suggestions? New pump? A bleeding process? Fluid change?

mine whines like a stuck pig at low speeds.. i ignore it.

My red car whined like rich17, didn't go away until I got a new pump. Yours is probably beat up from all the Auto-x.

Lol whined like rich17

I see what you did there

 

[smug]

I would leave it whine so it sounds like race car

It is quite loud, I thought the PS pump whine was bad on my GP.

Couldn't be a trans whine could it? Another possibility I remember reading when looking up how to shut mine up

i have a low mile oem pump, ive never had anything good to say about aftermarket power steering pumps for the most part (whiney, sticking valve, leaks etc) just get a good used oem unit.

Yeah, OEM all the way. Rich17, you'll probably kill most of your pumps, just part of the game. Even with a PS cooler, they'll probably still start whining eventually from the abuse they'll take Auto-Xing.

AGR makes a pump that'll fit most gm's
built with bearings not bushings

Actually there's a great writeup on how to put an MR2 pump (all electric) in a Honda, could easily modify to put In the lumina, and it costs less than $200 if done right. Electric ps FTW. Tis my next mod.

We were talking about electric ones over the weekend. Any GM's have em? He was thinking Equinox maybe?

 

[Turbocharged400sbc]

good fuckin luck, no way youlll find an electric that'll match a mechanical for pressure/volume that a Rustcar needs

Electronic Power Steering Conversion Delete Swap

^^^ link for the MR2 pump. The guy found that he didn't even need to run a PS cooler because his reservoir tank was double the stock one (which is a lot). This has been used in big Honda's and small Honda's, seems to hold up great. ~$100 for the pump, maybe $30 for the lines since you can probably make those at work, $50 for the misc. fittings, bam. No more whine, and no more overheated power steering.

Here's another link, for some reason the first one won't load pics for me. Might be the same for you?

thats for a system that flows half what the gm rack needs

 

[Turbocharged400sbc]

if rich was smart he'd go manual and get rid of those ropes attached to his shoulders

Blah blah blah blah, I'm sure it would work just fine.

 

[Turbocharged400sbc]

no it wouldnt, hydraulic systems need to be properly sized
its one thing to have a gearbox/rack smaller than the pump but to have the pump not flow enough is never a good thing with "power" steering.



sure wish i knew someone who has experience with rotating equipment/pumps

Ok, name the demands and flow a GM rack requires. Then name the same for a 97-01 Honda prelude. Explain the difference, and then give me the specs on the MR2 pump.

Annnnnd go. Seriously, prove you're not talking out of your un-showered ass.

cobalt
new Sonata

The cobalt one is pretty affordable, only $200-ish, but i doubt it's any better than the MR2 pump. It is GM though, might be easier to make work with a Lumina.

 

[smug]

I don't think there is a pump with the cobalt rack, I have never even seen PS lines on those cars

the gm pump vanes have alot more surface area than the honda/hyundai/mitsu pumps, ive pulled em apart, i have one on the shelf we used it as an ic pump on the riv, the gm pump moved shit faster at idle.
at the ~1000-1500psi working pressure of most racks you need a volume tailored to the spool valve and rack piston.
there aint no way that honda's steering was meant for the weight of a GM midsize chunk of steel.

besides its retarded from an energy standpoint as you loose efficiency at each change. you have to convert rotational power, to electricity, electric back to rotaional, to hydraulic power, to linear motion.

now if he got rid of his rack and went to a straight electric assist...that would be ok.

you can modify the valving and high pressure bypass orifices in the GM pump to get a bit less effort. and guess what it'll be cheaper

thats an electric assist rack, no hydraulics
