1989 F150 4x4 Swap Help
#19
Hello, Im new to the forum.
I have a 1989 F150 302 automatic that I want to make a 4x4. Please dont tell me to just buy a 4x4 as that doesn't really help me out. This is my first truck and got it for cheep. Im only 16 so I dont know all the things i would need to buy in order to make this work.

You can "just" put a 4WD tailshaft and tailshaft housing on a 2WD trans to make it a 4WD trans. But "just" doing that means completely disassembling the trans (the tailshaft is the last part to come out) and then completely reassembling it (properly). It's usually cheaper and easier to sell the 2WD trans and buy a 4WD one.
You really should figure out what trans you have in it now. There are threads here that show the shape of the pan on the various autos to help figure it out.
The main issue is if it's an electronically controlled trans or not. If it is it will be easiest to get the same trans as you have, but a 4WD version. That way all of the controls will be happy. If you currently have a non-electronic trans then staying with a non-electronic one is easiest, and it doesn't matter an awful lot which one you use (other than some linkage issues, which can be a pain but aren't show-stoppers).
The other issue is if you have an overdrive or not. If you do, going to a non-overdrive trans might make your engine spin awfully fast, which will make the truck louder and get worse mileage.
The C6 is a non-electronic, non-overdrive trans. Yes you can use one (a 4WD version), but if you currently have an electronic one you might have to deal with a check engine light, and possibly an engine that doesn't run well until you get the computer happy with the lack of a trans to talk to.

I'll chime in here. Unless you have mad skills or you have relatives that are well versed, I would urge you to sell your truck and find a 4wd truck you like.
The only way you will pull this off cleanly is to have a same year 4wd donor truck with the same transmission as yours. With the two trucks side by side, you might have the swap done in a month, provided you have some skill and knowledge. As much as it will be a bolt-in proposition (more or less), someone with little or no skills would have a hard go of it.
I have taught at a vocational school so I have observed the aftermath of the 'big project, no skills'. More than a few vehicles left on a flatbed, on their way to pick and pull.

The front axles will swap over pretty easily across the entire '80 - '96 range (you will need ALL of the front suspension parts from the 4WD donor, I'm not sure about the steering linkage).
The trans is where the actual year gets pickier (if it's an electronically controlled trans). There were a couple different electronic autos, and the computer for one won't run the other. And there were some minor changes at times that would require changing sensors or changing the wiring harness that can present some challenges if you don't have exactly the same thing.

If you don't have the experience required to fully dismantle/rebuild the front end of your truck I'm going to kindly suggest not even bothering to do it. Even experienced mechanics who have been in the industry for longer than you have been alive will say that it's not worth the trouble of doing it.
Why do you want 4x4 any ways? Unless you intend to put it on the trail you do NOT need 4x4. You could actually install a locking differential on the rear end that can get you off road just as well as a 4x4 can. That would be much simpler, less expensive, and that MIGHT be something you can try. But you don't sound capable of doing it. Sorry if that offends you, but that's the way I see it. I've looked into the process of converting my own truck and it just isn't worth it. Too many things can go wrong.

Well, my family is obviously going to help me. The only "trouble" from the many, many threads i have read say that the only problem is the transmission. All the other stuff swap right over without a hitch (except for the leaf springs being wider on the 4x4). Plus where i live you kinda need the 4x4. Im more than capable of doing this. Its called learning ya'know. Ill make a build thread and uh show you that i can do it.

Keeping in mind that the first thing I said in this thread was that telling you not to do this might be the most help we could give you...
I started my first serious car project when I was about 16. I did a frame-up restoration of a 1929 Model A (which is probably where my Ford addiction started). It took me 10 years to finish it, but I did, and I'm really glad that I did it.
I still think the best way to get a 4WD truck is almost always to buy it. But some times you just gotta do something. I'm betting this project will be harder, take more time and cost more money that you expect. And when your done you'll have a truck that's not worth nearly as much as you have in it. I'm betting that because that's how every one of my projects turned out. And I'm not sorry I did any of them (although I do wish I had started with a Bronco instead of getting a Jeep first). So go for it. Just know that all of the advice telling you not to is good advice too.
