2WD Frame, 4WD Components
I've got a 1992 F150 2WD that was wrecked. I've also got a 1990 F150 4WD that is a wreck. Is it possible to transfer the 4WD components into the 2WD frame? Also, the 2WD has a 5 speed standard transmission, while the 4WD has an automatic transmission. Both have the 5.0 engine. Would it be possible to keep the standard transmission?

You can bolt the 4x4 stuff to the 4x2 frame - they are the same.
As for the trans, I am going to assume it is a Mazda, given the year. If it is the Mazda, I think you can use it if you replace the output shaft with one for a 4x4.

if you decide to swap to the auto, you need to take the computer with it since its the E4OD that is computer controlled. Are both trucks the same wheelbase? dont forget the rear driveshaft will be shorter for the 4wd due to the transfer case.
Another thing you need to remember is on the 2wd F150s the rear leaf springs are 2.5" wide, and on the 4wd F150s (and all other F-series) they are 3" wide. This isnt a big problem. There are a couple ways to take care of it:
option 1: check your rear diff gear ratio on the 2wd, and the 4wd. If they are the same just leave it in there.
option 2: pull the gears out of the 4wd axle and put them in the 2wd axle
option 3: modifly the rear 4wd axle to fit under 2.5" springs. There are a few ways to do this one that I wont get into.
option 4: Mod the truck to take the 4wd's 3" springs.
Go do yourself a favour and check the door tags, get the axle codes off each truck and post them up. If the axle code is alpha-numeric (ie:H9) then its a limited slip, a straight numeric code will be a single wheel peel so obviously if one is a LS then you want it for more traction.

use your frame you will need to put the front 4x4 spring buckets On a 2x4 they are higher up. and related stuff on. I just swap rear spring mounts ( they may be rusted any way) And put whole rear end in.
The transfer will bolt to frame and hole should be there. As for the front cross member I have been told it was same but never did swap my self. So all parts should swap in.
As for the trans the 4x4 and 2x4 take different manual trans. The 2x4 are so rare here that those trans are gold.

Thanks for the info guys. I checked the codes and both have a 133 wheelbase. The 2WD axle code is 18, and the 4WD axle code is 19. These codes may mean something to you guys, but I've got to admit, they are just numbers to me. Can someone explain them?
Thanks again for the help.

For axle codes:
https://www.ford-trucks.com/article/...de_Chart_.html
The 18 is a 3.08 ratio open differential, the 19 is a 3.55 ratio open diff. You will have to take both axles from the 4WD to keep the front and rear ratios the same--they can't be different.
Your '90 likely is an AOD, not an E4OD, since you have a 302. AOD shift pattern is P R N (D) D 1. The E4OD would have a pattern of P R N D 2 1 with an O/D cancel button on the dash to the right of the steering wheel.

I thought that would be the case. Swapping the differential that is. I've gotton the 2WD pretty well stripped. I've just got the box to remove, then I can get it back into the garage and get it blocked up for 2WD componet removal. Again, thanks for the help and I'm sure I'll have many more questions real soon.

my truck is a similar creation, an 83 4x4 automatic and a 95 2wd stick. i kept the automatic since it was easier for me than getting another stick for a 4wd then having to find front and rear driveshafts since the 5sp would most certainly not been the same length as the 4sp automatic. swapping the auto column into the 2wd is easy enough also. i also kept the rear axle and springs from the 2wd. i just didn't feel like cutting the spring hangers off and swapping out for the 3in springs.
