I'm honestly a little confused what this conversion is? Anyone wanna give me the cliff notes?

On my old ramcharger there was a semi common mod to tap the power steering box at very specific locations, then run lines to a hydraulic ram attached to the drag link. The steering box fed the ram and basically split the power. It eliminated bump steer, stiffened the steering, and gave more power. Not street legal in the slightest and if you weren't use to it, it was confusing. (The steering would not return at all).

Your Rangers power steering pump is turned by a belt attached to the motor.

This pump is electric. Works the same way, but is self propelled.

Benefits:

No more noisy power steering pump.
Power steering works even if the engine is off.

Gotcha, my fiesta has an electric system like that. I really hope the Volvo system is better... my car handles like garbage.

My credo
it is easier to fix and understand than "her"
For curiosity's sake, how would this work powering steering and say hydroboost?

Obviously as it varied so would the brake assist, but how much?

we will find out soon. my truck has hydro boost and i need a ram.


This is interesting and a good alternative to using an inline electric power assist motor in case you want to keep hydraulic assisted steering. Can't wait for the article to be finished.
or electric steering and hydro brakes. totally shrink off the fead. and fit big blocks(think 460-5.4 dohc-coyotes.....or....mmmmmmmm the new big daddy 7.3 commercial engines over built for supercharging......

with what you and petro junky are bringing into the fray here.....we can drop these bastards in these rangers like they were briggs and stratton engines.


you guys rock(y)

Appreciate it. Should have the rest finished by tonight. My biggest problem was how few photos I took during the install, so may have to use some found ones.

I priced one of these pumps new on Rock Auto. $199.00.
Yeah, they are not cheap to buy a new one. Occasionally you'll see one on eBay for 80-120. Like everything Volvo, they're not cheap to keep up with. Failure rate seems to be seldom, though.


Gotcha, my fiesta has an electric system like that. I really hope the Volvo system is better... my car handles like garbage.
Not sure what the Fiesta is using. May look that up. What year and trim?

This one feels like a cross between a manual and power setup. Plenty of road feel without feeling too light or too heavy. Just isn't very responsive when sawing on it quickly. Good trade off in my opinion.

I really want to experiment with some of the additives to see what it changes.

2017 ST, but it has the "S" rims and tires so to be fair the terrible handling probably has more to do with the micro economy tires than the power steering system.

The Fiesta uses a manual steering rack and pinion with an electric assist in the column, no hydraulics.
