- front axle - driveshaft (front and rear) - transfer case - transmission - front leaves - steering components - wiring harness if auto t case its do-able, and im not gonna try to talk you out of it cuz i kno how it is to get a project in your head and just wanna do it no matter what. but its a lot of work and will definitely take a lot of time. if it was me id get the whole drivetrain out of a f150 7700 edition, the front axle out of a super duty and fab up some front leaf brackets. then youd have 10.25 axles, 3/4 ton leaves, a heavy duty tranny and t case, plus all the coolers and everything to make it practical
Thanks for the input there man. Greatly appreciated glad someone understand when ya wanna do something you gunna do it. And the only problem with getting a 7700 drive train wouldnt that run me a pretty good bit more than just getting some older stuff?
it wouls be more expensive but it would all pretty much just drop into your truck with no hassle. youd have to find a wrecked one and pull it all out
What year model where made the 7700 edition? 97-03? Or would just a 01 work? Not sure what all the changes in the drive train those years
they didnt come out till 99 i believe. an f150 heavy duty and a f250 light duty are essentially the same thing. but yea theyre all the same body style and most of the same stuff, just 10.25 axles, 3.73 gears, an LS i think? heavy duty tranny, and a tranny cooler and thats all i know
find a wrecked truck and pull everything out from underneath. hell of a project and yes i know you don't want to hear it, but trading trucks would be better
i am w/ you on doing it. something in your head and you gotta see it through. i almost did it to my 06 2wd. but then i started to get into what was really needed, and it would have been cheaper to find an exact match 4wd truck and start from there. like most people are saying, you'll need the Tcase, and prolly a new trans, or a shorter driveshaft if you are able to just toss the tcase on the 2wd trans (it is possible on some trans but not sure on these). you'll need to run airlines to engage your hubs. you'll need the steerin knuckles as 4wd are larger (taller) than 2wd. you'll want to swap out your coil springs and get a set for 4wd. i could go on and on as i had researched what was needed and truly, in the end, it would be easier to get a 4wd truck and then just do a solid axle conversion from there. i also remember you'll either need to flash your PCM or get a 4wd PCM to use on your truck as your current 2wd wont know know what to do w/ the Tcase, or front hubs or anything like that.
