Electric-hydraulic power steering?
#31
I found the remote power steering pump info. I had to look thru ~ 30 recent mags in my bathr... er reading room before I discovereed it was in an ad rather than a feature. It was being advertised as a new item from GM for street rods in Borgeson's (the steering u-joint people) ad. It said it was available in std and adjustable pressure for M2 R&P. I haven't looked to see where it's supposed to mount or how it's driven.

I see, I've seen alternators mounted on the rearend pinion, I guess a pump could be mounted like that and it would work real good until you had to parallel park.....lol
There's a caption at the bottom of this link stating the operating pressures of GM power steering, and from teh article I would say that Ford uses a lower pressure.

I was just reading this article also about GM hybrid Silverado trucks, they use a electric-hydro steering system running off of 42V. Here's the links;

Apparently Ford has been using the electro-hydraulic system for awhile also

I've been out of the wrenching business since 93 and don't look at(or keep up on) the new models very closely, I had no idea. Reading up on this has been a neat learning experience.

WOW! You guys are an incredible resource. I obviously need to get better at surfing the net.
Bobby - I hear you on the movement of technology. Before I bought my truck 2 1/2 years ago, I last had a wrench in my hand in 1970! This certainly has been a learning experience.
I have scanned thru the articles you all attached. Here's what I think I know so far. See if you agree:
1. This option sounds simple (just substitute an electric pump for the belt-driven one). It isn't.
2. The electric steering options (Honda, Delphi) are all brand specific and require sensors for speed and torque and a computer to tell the steering box what to do.
3. The electric-hydraulic systems (Subaru, MR2, EV1, Fiero) are juice hogs, requiring a lot of amps. (One article says the Subaru can drain the battery trying to prallel park).
4. Any of the options discovered so far would be pricy and, when grafted to a low-tech rod (no computer), would be very developmental. No bolt-ons out there.
It doesn't look like this direction would be very fruitful. So, after all this, I have come full circle. I think I'll start looking on eBay for a pump and brackets for my Cleveland. I can deal with that.
I thought I should bookmark this thread for the next fella who had this naive question. But then, maybe I'm the only one with that affliction.
Thanks all!

I don't know if it's model specific, but we race with a lot of different model Subies and have never heard of any having a PS related battery drain problems (and obviously we do a LOT of turning in autocross where there are no straights on our courses)?
Unfortunately with the lack of adequate driver skill training along with cell phones, heavier traffic, and other non driving distractions and the me too! popularity of land barges as family vehicles, computer assisted drive by wire is becoming more and more common and necessary for the masses.
RJ, what PS and front suspension are you using?

You can mount the power steering pump in front of the crank shaft and drive it directly. My friends 68 Lincoln is built that way.....not that this helps much but it is another alternative.
Oh wait the power steering pump is actually attached to the front of the engine block, behind the crank pulley. This is on a 460. Weird setup!

Not on the pump, but since this old, old thread I've been driving a car (Saturn) with pure electric steering. It all fits inside the column and dash, and is seamless. I suspect it needs a computer to control it, and a good alternator to power it, but it is just wonderful. No leaks, no belts.
