2wd to 4x4 conversion

[Trey7.3]

Will everything from a 2001 4x4 bolt on to a 2000 2wd frame? Both ecsb F250's. any welding to be done?

[blue99stroker]

if i remember correctly the frames are the exact same and everything bolts up.

[Trey7.3]

Good. And what's the difference in the trans? Will the transfer case bolt up to my trans I have already?

[Zaairman]

Transfer case won't just bolt up. Manual trans requires a new tail housing. Not sure about the autos.

[Trey7.3]

Damn. My trans doesn't have many miles on it. Once I swap the good motor to my truck ill move on converting it to 4x4.

[blue99stroker]

if they are both auto you need the transfer case and front and rear drivelines.

[Trey7.3]

They are both autos. Can I just bolt up the transfer case to my trans?

[blue99stroker]

im not sure ill look tomorrow when i go to class lol

I know 04 frames are the same for 2wd vs 4wd. I would assume all the early SD are the same. I converted mine to 4wd.

I just got done with a 4x4 conversion. You can't just bolt the t case to the 2wd trans. However you can swap the shaft out of the 4wd trans(it will probably bolt on fine but the shaft isn't long enough to reach the internals in the t case) and the tail housing then the t case will bolt on. In my case I swapped the whole trans cuz the 4wd one I had was rebuilt. Be sure to swap the crossmember out to. The t case will hit the floor board and vibrate like crazy.

I'd be glad to help with any questions you have. Feel free to pm and ill help the best I can.
