how complicated and hard would it be to convert a 2x4 into a 4x4 with a 2001 f-150 extended cab model?

 

You need the whole front end suspension or a solid axle to swap under, new transmission, transfer case, front driveshaft, shorten the rear driveshaft, new crossmembers for the transmission and transfer case. And thats just beginning the list. And it won't be cheap.

 

Cheaper and better to sell current truck and buy a 4x4. Would be expensive and complicated.

 

Basically, the only point to converting one is if you especially love that truck, or your wanna build some form of a monster mudder in which case a standard 4x4 wouldn't cut it anyways. But it won't be cheap or easy.

 

So If i could get my hands on a 98s front end and everything i need to convert mine to a 4x4 and i could also get my hands on a solid front axle both for a good price, would it be easier to use the IFS or SAS? and Id be doing all the work my self in my dads shop.
thanks guys.
And btw id rather jus convert my truck and not buy a new one. already too much work into this one.

 

SAS would be simpler but neither is "cheap"

a correct SAS should cost at least 4-5k IMO if you are doing your own work on it, if not double that. going past that 4-5k can easily be done

for a truck that old, i'd just sell and buy a new one w/ 4wd. then you know it's correct and will not have issues due to improper installation.

the front of the frames are different as well, so it would not be a "bolt on" thing or any where near it. SAS will make you do alot of research and fabbing.
