Adding power steering to an r4 questions

[Wolfpaak]

I have a 2004 R4 that has armstrong steering and I would like to add Power steering to it, if its not to difficult. Grand kids cant drive it, is that a good thing?, nah.

Any help would be appreciated.

Later,

Kenny

It’s relatively simple…but I don’t know if I’d make it too comfy for the grandkids

You can use an electric column out of a 2009 Nissan Versa (or other cars COROLLA, Prius, Kia, cube, Yaris)…easy to find a remove in the junkyard, don’t even have to get under the car! Get the whole thing including the steering wheel and ECU (computer).
I had to weld on a piece of angle iron to get it mounted, but the steering shaft actually fit perfectly onto my 2009 T4 rack.
Connect + and - to the winch battery connections and the third wire to a switched 12v source, and you can turn that beast with one finger.
Cost me $125 and I have been wheeling the Tennessee rocks and mud for years on 30” tires without any issues!
I’ve got a post on here somewhere about it…Joyner trooper power steering.

Grandkids are gonna have a blast!

[Wolfpaak]

Thanks mixfixdave!!!  Is the ecu for the whole car? or just for the steering?

We have 12 grandkids with #13 on the way.  Gotta keep em busy.

I' not familiar with new cars, AT ALL, they dont need a pump and rack?

Thanks for the help!

The ECU is just for the power steering…controls the electric motor/assist that is built into the column. Just follow the short wiring harness.
You keep your rack and maybe some of the original shaft (I did), the EPS just gives you some assist.
It’s also a great upgrade for an old muscle car because no hydraulics are necessary.

So the existing shaft on my rack fit perfectly into the shaft on the Versa column I bought.
It had a u-joint that I just welded solid.

Thanks for the pictures!  They helped out. 

The hunt is on!

Hey mixfixdave,

 

I don't want to hijack this thread, but I have a 2013 cfmoto uforce. It doesn't have an alternator it uses stator for charging the battery. Could I do this mod on the uforce,

[mixfixdave]

I am not certain…but other side by sides employ EPS, so I think it will work with a stator.

I ordered the steering column from the local wrecking yard ( they didn't have one on hand) $150.00 with tax. He didnt know if it would come with the control unit though. Was yours connected to the column?  It should be here this afternoon!

Thanks!

Kenny

[mixfixdave]

You must have the control unit, ECM/ECU whatever they want to call it. It’s connected to the column with a short bundle of wires.

[Wolfpaak]

It was there! Along with everything else,  except the airbag. Going to start stripping the un-nessesary things and then ill be back for info on how to wire it up. ALL wiring looks like spaghetti to me.

Thanks again!

Kenny

[mixfixdave]

Wiring is the easy part…
Big red and black wires go to your winch power connections (batt + -).
Then the orange wire from the ECU connects to a switched 12v source.
All the other wires are unused.
Turn it on (12vdc+ to orange wire) then give it 5 seconds and you will be turning with one finger!

[mixfixdave]

You can ground the big black (-) wire to the frame. Mine had short leads and I just extended the red (+) to the winch power.

Would these same power steering units work in a 2008 Trooper T2?

[mixfixdave]

Yessir…I have an 08 T4

[Mrusson]

Sweet! I ordered a unit off ebay and it should arrive next week. I hope you don’t mind me asking any questions I may have? 

[Wolfpaak]

Sad to admit, my project has taken the back seat to other things. I am wondering though, how much has to be removed to add the  power steering unit? Hood, dash...?

Thanks,

Kenny

[mixfixdave]

Just the hood…and you’ll be glad you did.
It’s so simple, don’t overthink it.

Here’s some info from my T4 install…

Well actually that's what I do best, overthink things!!!

Thanks again!!!
