This conversion is easier than anyone ever makes it out to be. Its actually REALLY easy. Buy a front axle (it bolts into place of the 2wd stuff). Buy a 4x4 trans/tcase. And install! Driveshafts should be easy to find at the junkyard, because you have a longbed. Before you start buying stuff though, consider anything you may want to eventually do to the truck.

For example, if you want to lift your truck, install the front axle the same day you do the lift kit. You have to completely remove the front end anyhow when you do the lift.

When you buy a transfer case case, consider getting your tcase from a Bronco instead of an f-150. All Bronco tcases are fixed yoke.

I'm not sure if you have a 5 speed or an auto, but if you have a 5-speed, try to find a zf-5 from an f250/350, instead of the m5od-r2 out of a F150. Better 1st gear, stronger trans, and still has O/D.

And since there are always people who think I'm talkin' out my *** when I say how easy it is.... here is my truck... started as a 2wd, is now a 4x4. Hopefully soon will be 8-lug with 4.10s and a sterling 10.25" rear.

I just did mine too and I did a 6in. lift at the same time, I picked up a dana 44 TTB front end complete from disc to disc, its a unique one (little did I know) Ford only made this version from the very end of 1987 to the very beginging of 1989. Where the hub assembly is one peice and pulls off with the wheel. I was trying to find bearings/parts for it and I didn't know what year it was from and I had one hell of a time. BUT anyways just know your #'s on your axles (year and ratio) you need to match your front and rear gears. And if you want to do a lift, do it now! it took me and two other guys to roll it under the truck and set up to mount it..... but total cost was $500

Soon after my rear end went out (had 3.70's in it) so I picked up a fully built ford 8.8 and I know its not the 9 inch but I wanted a direct plug in/bolt up with no problems plus I got this one with 4.10's and a detroit locker with the papers for warranty for $150

I'm looking for a zf-5 speed right now w/ a 205 t-case right now to finish up and do it right.

It is no harder than changing ball joints , piviot bushings or radius arm bushings.

Seems like everyone that has no clue how to work on a truck theirselfs make it out to be this long hard process to swap it out.

It is 4 nuts and 6 bolts that hold the whole front axle on. 2 radius arm nuts 2 bolts and 2 nuts holding the axles at the pivot on the cross member and the 2 bolts holding the springs to the spring towers.

now how hard could it be to take that apart?
