Electric Power Steering?
I've been having intermittent issues with my power steering pump. ....big surprise....
I'm a stereo guy by trade, and of the hundreds of remote starts I've done in the last year I've done several of the newer vehicles with electric power steering under the dash. A Ford Escape, for example.
Has anybody seen one of these models retrofitted to an old vehicle? I think I'd rather get one of these units and have a custom shaft go into the gearbox than any other method, unless somebody has reason to change my mind.
Any thoughts?

Electrically boosted, power steering. mechanical gear box, but instead of fluid helping it out, the shaft has a gear on it that is assisted by electric motor.
the technology has been around a long time, and is now starting to take off. it has potential in a lot of ways. The main thing for me is it's more efficient compared to the engine turning a fluid pump all the time. Also, they tie it into traction control nowadays for assisted steer when your front tires aren't gripping evenly and it pulls one direction.

here's a read on the safety end of things.

I"m not sure if the system ford uses now is stong enough for a full size truck, or if you can make it work without the BCM and all the fancy stuff.

"EPS also won't work in HD pickups with recirculating ball power-steering systems. The parasitic load is too high for a 12-volt electrical architecture to provide enough torque. One possible solution to this issue is to apply some of the lessons learned from EPS to provide more intelligent hydraulic power assist that can vary boost levels based on driving conditions"

guess not...
anybody put a big rack and pinion on a dent? haha

Any chance you could use an electric motor to spin a standard power steering pump?
People are no doubt going to argue that this would be LESS efficient than driving the pump directly but I will argue differently. Electric water pumps free up horsepower because they have an impeller designed to flow well over a very small RPM range, and it turns at more or less a constant speed relative to engine RPM. A standard water pump has to work over a wide range of RPM's and is thus not extremely efficient.
You could use the same principle for power steering. Figure out what type of RPM you need to turn the pump at to provide adequate power assist and then find the most efficient 12v motor that could do it, assuming such a creature exist that could withstand continual duty.

Makes sense to me. Better yet, have an electric motor with a load-sensing circuit so it bumps up the pressure if you're turning hard. the thing would hardly have to run when you're moving.

I have been contemplating the use of a Toyota electric power steering pump on my '54 F100. They came in MR2 Spyders, all-in-one pump and reservoir. I don't know anything about how they are wired though.
