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.

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.

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!

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!

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!

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

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

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

Thanks again!!!

      We have a 2018 Cub Cadet Challenger 400 and I found this Internally Threaded Bolt with a 10mm head size laying in the floor of the shop bay here on our ranch where we park the Cub Cadet.
      Trying to figure out where it belongs...

      2022 Hisun Sector 550 eps. Power steering not working
      By A P
      Hi
      I have a 2022 hisun sector eps 550. 30amp fuse is blown for eps. Checked the motor and it’s fine. Opened up the controller and found a bad diode. Dealer wanted 500$ for the controller. Just posting this in case it helps someone. I couldn’t read numbers from the old one so just took a guess and replaced it with a 100v 3amp diode.

      Help! Hub safety-hour meter switch problem
      By Texjpr
      2002 ranger 500 4x4 stopped running and wouldn't restart. Service manual wiring diagram helped identify the hub safety switch as the culprit. Using jumper wires to bypass  switch allowed the engine to start and run normally. Inspection of switch showed melted epoxy and a strong smell of burnt electrical. Unable to find replacement part either used or new. Is there a work around other than jumper wiring?

      2021 Hisun Axis 500 No Start - Need Help Please
      By Hunterman22
      2021 Hisun Axis 500 UTV (From Lowes)
      Will NOT START
      MY apologies if this is to much info just wanted to give yal the most information possible for help.
      I'm a so called diyer. An Electrician by trade 21yrs. I got my S×S from my last job. The contractor purchased this S×S for this specific job brand new, from Lowes. They used it for hauling materials, tools, & a little bit of anything you can think of on an Industrial type job site. 
      I remember getting on the SxS one time & pushed the gas petal all the way to the floor & SxS had very little power. 
      So anyway ,when the job finished up back mid July this year (7/2024) , I asked the contractor what they was going to do with it. I was told to take it. Otherwise it would go to the contractors yard (storage yard) & most likely rust away. 
      Took it home washed it , it had a heavy coat of dust on it & in it dust was every where. My helper & I had to push it on the trailer to get it home.  After washing it throughly I let it sit & dry out for a good day and half, maybe 2 days. Before trying to start it. NO START. Will turn over & try to start but thats it. 
      So here's what I've purchased & installed. New Air Filter, new spark plug, new air idle control valve (AICV), new throttle position sensor, new throttle body, new oxygen sensor, new digital dash speedometer/fuel gauge/clock. 
      Also drained the old oil & gas & replaced with new oil & 93oct. gas. I should probably mention that I've changed the AICV twice. The 1st time I changed the AICV I was able to get the SxS started & let idle for at least 10-15min. Drove out of the garage, with very little power,  turned it around & barely got it back in the garage.That was the one & only time I've been able to start the SxS. I've also cleaned the Throttle Body and & intake with TB cleaner.  So after that the AICV was  making weird noise so I pulled it out & tried cleaning it, pretty sure I messed it up. So I purchased a Throttle Body that came with new AICV & TPS. Still NO START.  I've checked the fuel pump & the fuel injector.  I took the injector off still hooked up to wiring & turned the key over, the injector sprayed a lot of gas out kinda the size of a volleyball. I've also checked the clearance gap on the intake & exhaust valve. But today 11/2/2024 I'm going recheck spark plug gap & the valve gaps. And alot of other checking. Would the driver side seat belt have anything to do with it not starting?? I know the driver side seat belt has to be in gauged for full throttle "going fast". Thing is the drv. side seat belt will latch but feels like might be messed up inside of it. Tired opening it up but to no avail.  I've never had a S×S or 4wheeler so I was really excited when I got the S×S,not so much anymore.  I work on & fix my own vehicles usually no problems.  But this SxS is kicking my ass.
      So if possible & someone could help me with some ideas or tell me what Im doing wrong or did wrong, I would greatly appreciate it.  Thank you for reading thus far.
