EPAS

This is probably the easiest way to have power steering.
Connect this up to the stock steering box and then to the steering column and you have power steering. Of course you'll have to make a bracket for it and wire it in

It has a power lead and a ground lead thats it. The module is bolted to the unit but I'm told it can be removed and relocated if needed. The side with the long shaft is cut off and shorten if needed.

Tons of YouTube videos on installing this. One guy even installed one in his tractor.

Came out of a 2006 Saturn Vue, cost was $50 for everything in the picture

Don't ask for any more dimensions or info on it because its off to its new owner.

How difficult was it to remove?
Remove the cover on the steering column(I think it was 4 screws)

2 bolts hold the column to the frame mounts

3 bolts hold the column to the unit. Once this is done remove the electrical connections and the column slides off of the unit

1 long bolt holds the unit to its mounting bracket

remove the universal joints that connects the unit to the rack and pinion unit



How long did it take?
First time it took maybe 30 minutes. Second time took maybe 15 minutes.

One thing I should mention for those wanting to install this unit.

The years that this unit came in I think are from 2002-2007

You can tell if its the right unit by the module box. It should be made out of steel. Later ones are made out of plastic.

This info was found on various sites that used this unit

After some time having installed an EPAS in my car I thought I'd comment on what my thoughts are on this.
Its only been a couple of weeks since I got it operational but I love it. It really is handy at slow speeds like parking or making slow tight turns.

I guess the most common EPAS unit that people are using are the ones with a fail safe mode in them.

This is a copy paste from another site of the units that have a fail safe mode.

Below is the list of Cars that I know of that has Fail-Safe Electric Steering. Only 3 wire connection. Ignition On, Power and Ground to the Steering ECU. That's it !

2004-2009 Toyota Prius
2009-2013 Toyota Corolla
2006-2011 Toyota Yaris - (With ABS)
2007-2009 Nissan Versa
2009-2012 Nissan Cube
2012-2014 Kia Soul

ECU Part Numbers:

2004-2009 Toyota Prius 89650-47102
2009-2013 Toyota Corolla 89650-02300
2006-2011 Toyota Yaris - (With ABS) 89650-52120 / 52050
2007-2009 Nissan Versa 28500-EM30A / 991-30303
2009-2012 Nissan Cube 28500-1FC0B / JL501-000932
2012-2014 Kia Soul B2563-99500 / 4PSG1312 / FPSG1312

The output shaft on Toyota is little larger than the rest and therefore the Borgeson 312500, 11/16 36 X 3/4 smooth bore weldable coupling should fits nicely. This couple fits the others as well. The Kia EPS is the biggest and appears to be most heavy duty. The Prius & Corolla EPS are very easy to find at salvage yards so this is the best bet. I picked up these EPS for testing for $35 each at my local pic-a-part

Here is the site. I don't know if this was the origin of the info or just copied over also.

I would highly recommend this modification.

I don't think I covered the install in my build.
I am using the oem EPS steering unit that went with the dash since they matched each other.
After numerous attempts to get the unit to work (it didn't have a fail safe/limp mode) I found a control module on ebay that made it operational.

I also installed rack and pinion steering in the car

When I pulled the EPS unit I also pulled the shaft that went from the column to the steering box of the donor car. That way I had the universal joint that bolted to the unit and that shaft had a collapsible feature to it for safety purposes.
