2wd to a 4wd ?

[EBSTEVE]

I have a friend that has a 2wd 1990 3/4 ton Ford that he wants to make a into 4wd has anyone done it or checked into it I figure that you could get all the parts and bolt it on. Any info would be great I am going to look at it in the morning to see what I can tell the only reason he wants a 4wd is for the snow in the mountains so flex or off road ability is not a concern.
Thanks

What I would do is find him a Dana 60 that is leaf sprung maybe seance he dosent care about flex and all that would be the easyest way to go. After you have the D60 and leaf springs find you a X-case that will fit not sure what trany it has but might have to get an adapter to bolt the x-case to the tranny, ohya you cant forget the front drive saft to. For mounting the leaf springs you would have to custom fab some mounts and stuff. There is a post a couple down called Solid axle conversion || Coils or Leaf springs? that shows a prety good way to hook up leafs up front. Other then that I cant tell you much more basicly just compare his to a 4wd and what ever de dosent have get and put it on.

Thanks for the info but I am looking first for if it will bolt up. I would figure that the TTB stuff would be easy to find and cheaper than a 60. I am sure I can do a solid axel swap and either leaf or coil but then I am dicking with stuff forever and doing allot of little fab work that takes up a ton of time and for the application I don't think it is worth it. I did not mention but I am doing the labor for free and he is buying the parts so easier for me = better for me =)

Steve if it is a Twin I Beam, I beleive the TTB should pretty much bolt up to the same brackets. Have you looked at a '90 4wd and compared?

I was looking at doing this to my tow rig
its a 91 f250
Grabbing a 150 (coil sprung) D44 TTB complete and then your going to need an transmission with tcase (no adapters that i am aware of will bolt it)

[EBSTEVE]

Not yet Paul I just found out that I am doing this last night. I am planing on looking today I just have to go deal with the state on my unenjoyment. We missed you Sunday and did not see any Canadians at all? That FU(KING expressway got me again no busted axles this time but I debeaded my SX and tore the valve stem from the inside.

Steve, I honestly think the solid axle would be faster and easier. The end result will be better and you won't have all the TTB alignment problems.

It currently has leaf springs up front right? If so, all you need to do is weld some perches to the axle and bolt that baby up.

I thought all 2wd f250s had coil front ends just leafs on the 4x4. I know that rangers use different engin cross members between 2wd and 4wd so you mmay want to llok at that as well. if you use a f150 TTB it will be 5 lug compared to 8 lug that rear is. Will dana 50 outers go on there?

What about for a t case useing a divorce mount np205 going to need differnt driveshafts anyway this way you dont have to mess with the tranny.

I am pretty sure that 80-98 4x4 F250s had TTB. If the guy is looking for a 4x4 to get through the snow, then bolting on the TTB shoudl be the easiest. They are on the same frame at the F350(which had a solid front), so leafs would not be that hard but the TTB should be pretty simple. If the crossmembers on the 2wd and 4wd are the same(i think they are), then it should be just bolt on. The TTB F250s had a D50, not the F150s TTB D44.

so then what you are saying is that 80-98 4x4 F250s should have everything I need. I did not get a chance to look today maybe tomorrow

[SwampDonkey]

sorry i was unclear.

I am sure that 80-98 F250s have TTB. I am also pretty sure that the 2wd and 4wd have the same radius arms and springs. If the 2wd and 4wd have the same front engine crossmember, then you should be able to bolt the TTB D50 from a 4wd F250 to a 2wd F250. I have never done this, so don't take my word for it, but I am pretty sure. You will be converting from a twin I beam 2wd to a "TTB" setup

Of course, you will still need to get the tranny/tcase from the 4wd F250 and make provisions for the shifter

Here's the deal- 80-90's 2wd f-150, 250, and 350 all use coil fronts. 80-90's 4wd f-150's and broncos use coils as well. the 4wd f-250's and 350's use leafs for both TTB and straight. What you can do for a easy bolt-on swap is use 1/2 ton TTB from a F-150 or Bronco since they also use coils. Using TTB from 4wd f-250's and 350's will be more difficult as that involves converting to leafs. I was kicking around the idea of converting my '91 2wd f-250 to 4wd but haven't come across a 4.10 front TTB yet at the u-pull-it place.

Oh, and if you go with the 1/2 ton stuff, you'll have to run 5-lug wheels in front unless you convert to 8-lugs using 3/4 ton chevy parts.
