i am 20 years old and i drive a 1992 xlt 2wd. i was wondering if there was some way that i can convert my 2wd into 4wd? if anyone knows how please tell me. i was thinking if i took the 4wd off a same year and model f-150, if they would just bolt right back onto where the 2wd parts were. if anyone knows how to help me convert my baby into 4wd please give me a hand. i would greatly appriciate it.

 

Well you can its not that hard from my understanding simpler solution is to go and buy a 4x4 but if you want to the swap get the exact same truck with the same specs with 4x4 from a junkyard like a donor truck

 

Or you can do a straight axle conversion like this

Also, check out http://www.pirate4x4.com and see their solid-axle swaps forum.

Here is some more chat talk about this swap: http://www.fullsizebronco.com/forum/...ad.php?t=24977

Also do a search on this site for more. This has been talked to death around here and other sites. Where this parts list says 94 just use the year of your rig. I got this information from 78F3504x4 here on this site.

-78 F150 Dana 44
-78 lower coil cups
-94 F150 upper coil buckets (stock)
-4" lift Skyjacker coils for a 78-79 F1504x4
-90 F3504x4 drag-link
-78 F1504x4 tie-rod
-78 calipers
-94 brake hoses
-78 brake line (on the axle)
-78 ford hubs
-94 F1504x4 pitman arm (Rancho drop)
-4" lift shocks for a 94 F1504x4
-78 F1504x4 radius arms
-78 F1504x4 radius arm brackets
-custom 18" adjustable track bar ($40 from local race car shop)
-custom front shock mounts (single)
-dual steering stabilizer I rigged up from my old TTB one.

We welded 1/4" thick steel to the engine crossmember before drilling a 3/4" hole to mount the track bar. I used the track bar mount on the axle, and it lined up perfect to the crossmember.

Also, some other stuff:
-4 degree c-bushings
-front 94 front driveshaft fit perfect on the 78 axle
-the 78 driveshaft u-joints are the same as 94
-If you like the dual front shocks, you can get the bracket from a 77-96 bronco

 

The swap is fairly easy if you have the complete donor truck. I emphasize complete because I came across some parts like the front end assembly (completely bolts up to the 2wd bracketry), tranny was a different one than the intended 4x4 version from Ford and couldnt find a 4x4 tranny crossmember so I fabbed one up, I went with an old faithful NP205 so I had to make a shifter and custom driveshafts (Rear shaft from an 86 bronco w/AOD fits front if you want that t-case), and I went to the 9" rear end for the amount of them I had lying around and changing the gears/carrier is much easier when you blow them up. The only fun part of the swap was the rear springs. Ford used 2.5" rear springs in the 2wd and 3" wide springs with a factory lift block in the 4wd trucks. The frame brackets are also an inch lower to get more ride hieght out of the rear. A torch or drill is required to remove the rivets that hold these brackets on and should be reattached with grade 8 hardware with locking nuts for safety reasons. I also had fun with my swap cause my I6 was toast and I had a 302 truck easily accessable so I swapped it out, which gave me some serious wiring to do. Completely do-able with a decent set of tools and alot of time to play with it. I had fun, and learned alot. By the way, I am only 21.

 

In 78/79 they used two different sized u-joints. The larger style joint is the same as the 94, but the smaller ones more common in the early months of 78 will not work. If you are looking into a solid conversion, which is freaking cool by the way, you will be better off when ordering rear springs for the 4x4 version of your truck, which will require the new frame mounts. This also will help with leveling between the 4x4 front end and the lifted 2wd rear end, making it so you dont look funny with the nose of your truck higher than the rear.
