HELP - 02 F-250 front axel to a 2010 + straight axel with coil springs & Lift HELP

2002 Ford F-250 XL Super Duty 7.3 Diesel 2 Wheel Drive with Coil Springs
*
There are two options I would like to do to this truck:
*
1.*****Find a 2010 or newer front differential (straight axel with coil springs) to make the truck 4-Wheel Drive.
a.*Leave the current transmission until it starts to go out (it only has 170k miles with no problems).
b.*Then when the transmission does go out the new differential will be ready to hook up.
c.*Will the new model front differential Mount to a 2002 Truck?
d.*Is it plug and play or is there lots of fabrication?
e. Are their electronic issues with hubs and transfer case?
f.*Then put on a 4 lift kit
Or
*
2.*****A 4 Lift kit for a 2-Wheel Drive
a.*I have been looking everywhere but can only find 6 for a 2002 2-wheel drive
b. The only 4 lift kits for a 2002 are for 4-wheel drive with leaf springs.
c.*Would a different year truck 4 lift kit work on a 2002?

The first problem is that a coil straight axle (2005 and up) is wider than a leaf axle.

Second problem, are the steering boxes the same?

I say sell what you have and buy a 4x4, it will cost less in the end.

Finally, a lifted two wheel drive is like a padded bra, it looks nice until you really want to play with it...

it sounds like this wouldn't be too bad on your truck. are the coil springs the same distance apart on the axle? same diameter?

i think you'll just need to get a hold of the front end parts from an '05+ (trac bar, steering box, tie rod, radius arm brackets)

replace the rear axle with an '05+ at the same time. you'll need 17" wheels for this conversion also. make sure the gearing matches front and rear. you might get a better price if you find a matching front and rear axle together from an '05 which will most likely come with a bunch of other parts. a guy near me sells axle sets for $300.

then you need t-case, trans, driveshaft. if you get a manual t-case you don't need to worry about wiring. the stock hubs are either manual only or manual/auto which will function just like manual hubs so you won't need to worry about that.

the lift kit you'll want will be for a 2005-'07 4wd

Putting an 05 and up axle under your 02 means either an 05 and up rear axle is required OR 2 different sets of rims for the front and the back. The front wheels will require 2 inches more back space than the rears to keep the front and rear tire widths the same.

Given all of the little pieces you'll need, the best thing to do would be to find a totaled 2004 older 4x4 donor truck.

Love the padded bra comment.
I agree with these guys, converting a 2 wheel drive is a ton of work and not even worth it!!!!!
Get a 4wheel drive model or at bare minimum a totalled truck so all the parts are there.
It's not worth screwing with and a jacked up 2wheel drive truck just looks stupid............

We mainly use this truck to haul horses since it has got more cojones than my ’87. We use the ’87 to go out and play in the mud and snow it’s jacked up with 4 wd. I am looking for some way to get the 02 a little higher off the ground when we are at the ranch.

I thought a little 4” lift would be good to get the clearance and wont ruin pulling our trailers. But I have not been able to find a 4” for a 2wd. Does anyone know where to find something like that.

Also been looking into 2” leveling kit but not sure if that will be the right height either since it has the heavy spring in the back. Looks like a stinkbug going down the road.

If anyone has any input I would be happy to hear from you. Thanks!

I Changed mine out it wasn't that hard. Most of the bolt holes are already in your frame. As for the pitman arm you can buy a ream to enlarge the hole as the new trucks use a larger ball joint. I went with a 06 axel and a Pure Performance 6 inch lift. The ride is fantastic but the real deal is that it now makes u turns. Talk to Cary at CT performance as he has done many of these and can help you with the parts you need as well as the expertise to make this happen. I did my truck 3 years ago and the only reservation is that I didn't do it sooner. If you have any questions please send me a PM
