I ahve been asked by Adamstrator to write a short description of the mods that I found to be needed to correctly accomplish this Modification. I must say first that what worked for me was what I felt to be the safest and maybee not the fastest. I will try to warn you of the pitfalls that got me. That way you will not have to fall in the same ones.

Just to say this all started at my buddies shop with the install of a 3" body lift. Well as you see the body lift was returned to the store. I will try to provide a link to the pic as I go that best describes the set up

OK here we go, First off you will need to locate the front knuckles off of a D 44 from a chevy donor. At this point if the dollars was not at an extreme issue you could locate a 78'ish F-150 D-44 and have it retubed. This would do two things it would give you the reverse cut (high pinion) diff which would aleviate a lot of hassels later and 2) it would give you the opertunity to propperly set up the camber and caster. If i had to do all over again I would go this route I might just go this way w/ a D60 http://www.ifsja.org/ubb/smile.gif

Once you have the parts tou need to have the steering arms made and the spacer blocks made to look something like these. http://albums.photopoint.com/j/ViewPhoto?u=187566&a=11248759&p=40358579
The bolt pattern imitates the pattern on the driver side bolt pattern on the knuckle. http://albums.photopoint.com/j/ViewPhoto?u=187566&a=11248759&p=40358571


You will need to remove the axle and be able to hold it level while you weld the new spring pads on the diff. Take notice the cast that has to be ground away to let the pad lay flat on the top of the tube. http://albums.photopoint.com/j/ViewPhoto?u=187566&a=11248759&p=23652642
As you can see the tube was reinforced to add some strength around the cast
I will also tell you not to weld the perch on all at once it might distort the tubes. OK what next?


You can then hang the diff on the rig. Once that is accomplished you should be able to install the knuckles (with new ball joints of course) and reassemble. You will need to mount the shocks in a new location and the stabilezer along with the sway bar. http://albums.photopoint.com/j/ViewPhoto?u=187566&a=11248759&p=40358575

Once the diff is done you will need to modify the crossmember to allow for the drop in the dront shaft( this is where a reverse cut D44 would be great)


There are a lot of little things that I am sure that I skipped over but they should obviouse to the person doing the work.

Last note I put two tie rods on my rig because I was knocking the Toe out on the rocks. Since I have the dual set up there has been no probs

Here is a link to the complete high steering setup. If you have any specific question please feel free to E-mail me and I will help you where I can. Good luck

To much information, circuts are shutting down.

That is a great write up! I cut and paste it into word so I can pick it apart better and use what I need.

Good write up! There is one common misconception in the crossover steering definition that most people in this forum seem to have and that is that the above article is converting a FSJ to crossover steering. FSJ's ALREADY HAVE crossover steering! Older rigs have it moer than later rigs. The above article is a crossover steering correction how to that will inprove what we already have. The big reason everybody wants it is the steering systems on Chevies and Dodges are terrible when lifted and very hard to get rid of the bump steer that occurs without expensive parts. Take a look at your buddies 4x4 Chevy and you will see what I mean.
Once again good write up and for more info see the Sept 2000 issue of 4 Wheel & Offroad.

Jeepbob,

This is why I referred to it as Hi-steering. I am removing the draglink from my tierod (which is under my spring now after the SOA) and moving it to the steering bracket that will be mount adjacent to the upper balljoint on the passenger side knuckle. With the amount of lift I have, even with a 4" drop pitman arm, the vertical distance between my tierod and my drop pitman arm is 9"!!! http://www.ifsja.org/ubb/eek.gif The longer the distance is between the two mounting points, the less of an angle you will have, thus reducing bump steer on extreme lifted vehicles. I understand the misconception entirely....

Just a thought RB, if you dont have the upper tierod like fullmetal has you are steering the whole rig from the pass side. seems like this would put all the stress of the steering on one tierod end. (pass)
Whereas FM still has the force from the gearbox distributed to both sides evenly. And also the feedback force from the wheels to the draglink. Does it seem that it would be weaker?? Im just floating it around in my head and wondered if it would make a difference..

For instance if you hit a curb with the driver side tire all the force goes into the pass side tierod end(and stabilizer) where stock it goes into 3 points. (inc draglink)


Again just brainstormin.

RB I was not knocking the article or anyone as it is very useful, I just noted a (perceived on my part) misconception among some of us as to what crossover steering actually was. Personally, I will be using your info soon, so thank you for the info and Definatly no offence meant at all.

None taken... thought it would be better understood by others to ellaborate.... we are family here http://www.ifsja.org/ubb/wink.gif

I'm glad you can use the info... you have helped me as well http://www.ifsja.org/ubb/biggrin.gif

I hope the pitfalls that I feel face first in will help somebody else not make them. I thought about some other things over the weekend so here is the list.
1) ensure that the steering arms have the appropriate curve to them because as you move the linkage up you will hit the tire. So if the are not machined in or curved enough you will be stuck with a differene offset in wheel spacing. Hey this is not totally a bad thing, I decreased my turning radius http://www.ifsja.org/ubb/smile.gif

2)As you knoiw serious things in the rear will need some serious attention RB has a good write-up. I did mine very similar.

3)Don't forget the longer bump stops' brake lines' etc.

4) Then the one that I have not completely solved and really pisses me off that I have not solved it yet is the Emergency Brake cable http://www.ifsja.org/ubb/frown.gif

Just an update, Tha ATLASS is AWESOME!!!!!!!!!!! Just got back from the Safari Pre run and it worked great. Never thought an Automatic would engine brake http://www.ifsja.org/ubb/smile.gif

Good luck and keep the rubber side down, Well most of the time
