EPAS systems are the future. The Ford F150 pickups are now running electric power steering. It is becoming quite common.
So common that last Thursday I opened a box that came from Europe with a complete EPAS system for the Pinzgauer. We expect to get it installed in the next week or two and see the results.
Discussions are already underway in regards to the 404 units.
If you look at the benefits they are huge.
#1 - "Assist" is programmable. You have a little dash mounted knob that you can adjust for more assist and less assist.
#2 - No Disconnect Within the column. Lose the assist and you still have your regular steering.
#3 - Ease of use/installation. Very straight forward installation with no permanent modifications required. Wan't to return back to stock....a couple of hours.
#4 - No power steering pump needed, no hoses, no HP drain on the engine.
Only drawback I can think of at this point is we are having difficulty with finding these in 24V. Amp draw is not that bad, but an electrical system modification will be required to get the 12V feed.
We shall see. I'll drop in a video of our installation on the Pinz. Hope to get a couple of 404 columns up to the manufacturer in Germany for testing/fitment soon.

First and foremost you are messing around with one of the most important if not the most important system for a vehicle. Secondly, most of the units in the junk yards are going to be integrated into numerous computer controlled functions.
There are also numerous configurations. From what I understand the manufacturer of this unit has a selection of 40+ electric motors based upon weights, forces, ratios, etc.
The unit we are testing here is made by EZ Powersteering. EZ Electric Power Steering
It appears to be pretty plug and play, designed for our application, computer controls taken care of and a sensitivity knob.
I'll let you know how it goes.

Very sweet setup Scott! I will be excited to see your results. That will make both the pinzgauer an the 404 so much more fun to drive.

404 Power Steering
Wanted to copy Scott's post about the new EPAS setup he is testing in a Pinz to it's own thread.
Seperated out for future search and future updates for 404's

I don't know enough about the systems to be considered any type of expert. Like I mentioned we are just beginning our investigation of the systems. Brian my engineer took a trip out to Colorado and test drove a Pinzgauer with a an EPAS system installed. The work had been done locally, but based upon his observations and positive evaluation we went looking.
I can speak to the concern of the stock 404 steering box. It is built very strong. So strong in fact that we don't sell that many steering boxes.....evidenced by hundreds of New boxes sitting in inventory! Failures under normal circumstances are rare.
In addition in the late 1990's we offered a power steering system that mounted a Char-Lynn hydraulic torque generator into the steering column of the 404. We delivered in the range of 15-20 full kits. These units were used hard and I do not know of any gearbox failures as a result of the additional forces put through the box. Small sample, but definitely gives me a positive feeling. That system had some major drawbacks....think 1970's Cadillac with a trunk full of bricks.....
If you do some research on the link I provided it looks as though the EPAS units that we are talking about have a clutch system built in. If they receive too much resistance the clutch will slip. This is applicable to your question about being tight against a rock. It is also one of the reasons we are pleased to see a "specialist" company that takes these types of question into consideration when making up the motor/gearing combinations for the various applications.
My shop has done a number of the 406/416 type conversions. They can be done very nice, but they are a lot of work and not for the faint of heart. Not to mention you are cutting your frame and pretty much making modifications that cannot easily be reversed.
The other thing that you may want to discuss with those that are running the 406/416 systems on the 404's are the steering arm failures. I know of at least 5 conversions who have all had steering bolts break out of the knuckle causing some issues. If I'm not mistaken Eric Messersmith has torn his bolts out of his knuckles on at least 3 occasions...?
In regards to production/delivey/etc. I do not know when or if we would even offer this type of system. Initially, we are trying these out ourselves to see what we think, but I am not even sure if we would offer them. In todays world it is about Liability. We had to renew our liability policies this year with a new carrier as our business has grown to the point where the parts sales are substantially more than the dealership vehicle sales. With that renewal came a 66% jump in premiums. Blindsided does not even begin to describe it. What was very interesting was the insurance companies interest in exactly what parts we are selling, to who, and the risk they are taking on. Realistically if we do pursue offering this kit we would probably not have initial testing done for 4-6 months.....However, there is nothing stopping anyone from being the guinea pig themselves.....again I posted the source for a reason
Hopefully this helps. Cliff Notes: I think it's going to be a viable option on the 404, but will not know for quite sometime.......

Sweeeeet! A 404 with power steering would drive better than most cars on the road. They drive so nice already the noise and lack of power steering are the only things that tell you your driving a truck. I have been in many a situation where power steering would have made things so much easier.

This could be a winner. It is unfortunate that liability issues would become a barrier. Running a small business today is tough going on all fronts. Maybe I could get the insurance company's risk manager to try a 3-point turn in my 404 with a snow blower hanging off the front....
