For my next project I'm converting my 2wd F250 to 4wd. Reason for doing this is because where I moved to the terrain calls for 4wd as where in Ca mostly everything is compact. The truck is a 2002 F250. Parts were sourced from model year 99-04 trucks. Early 99 Fords have some different parts. The most easiest way to get everything is to find a truck with a complete front end.
You'll need an axle, track bar and bracket, leafs, pitman arm, brake lines and brackets, shock mounts, sway bar, speed nuts, and little things. Big items is the pitman arm and the speed nut for the track bar bracket. Depending on the model year, 99-01 trucks you'll need the front hanger assembly. 02-04 trucks come with them as the crash bar assembly. Everything is unbolt and bolt back on except the coil buckets. You have to cut the rivets.
I opted to have my axle rebuilt. My cousin found it for me and we hauled it John at Domestic Diesel in Chino and he rebuilt it on the bench. I got new U Bolts from Sunrise Ford parts. I got into Chino last night at 1:30 and went straight to work. The 2wd suspension takes time to remove. By 6am I have the truck sitting on the axle, using the old U Bolts. I went to Sunrise to get the parts came back and took a nap. Got back to it at 2pm and drove it over to Flos at 6pm. Got new u bolts installed and rear blocks. I still need to remove the old coil buckets and reinstall the bumper. I will need to extend the rear brake line from the frame to axle.
All in all it's a little bit of work. More than I thought. Years ago I swapped a Dana 60 into a 95 F250 with TTB and put the TTB suspension back in the F350, all in 3.5 hours.
This only covers the suspension. I still have a 2wd transmission. I can get a 4wd unit or have my 2wd unit rebuilt and install a different tail housing and output shaft. I will be having the 2wd tranny rebuilt and converted over using a manual transfer case. John Wood will be doing that. New drive shafts will be needed. I'll get some pictures uploaded here soon.

Couple notes. Torque the pitman arm nut before installing the track bar bracket. Use power tools where you can. Track bar bolts get torqued to 400 ft.lbs. and the pitman arm nut is 230 ft.lbs.
Around 03 to 04 Ford changed the thread pitch on the lug nuts. The axle I got didn't match my truck. When it got rebuilt I had new unit bearing installed with the 02 thread pitch. The shit Ford does.

I want to convert my 01 to 05+ suspension. The new ones turn so much sharper and the coils are a lot smoother ride. Good job on your conversion.

Back at it. Trying a carbide tipped hole cutter to get these rivets off.

Good luck. You might be better off grinding them off. What ever shop you are at sure makes things easier. I think you should take it home and do all of it in your driveway so the rest of don't feel so bad.

Ended up using a grinder for the rivets. The holes for the shock mount are already there.

So after about 1 second of drilling it was clear to grab the grinder. I'm doing all this at the family hangar in Chino. I'm making do on tools. Everything to make this job easy is in the service truck but its 380 miles away.

When removing the buckets a grinder is the easiest method. Grind the heads off the (6) rivets. From the engine compartment grab something like a tire iron and wedge it between the frame and bucket. Whack it a few times and the bucket will fall off.

I thought I had more post in this thread but have an update. Dana 60 has been in for about 5k miles now and all is good. Did have to tighten the tracbar mount where it bolts to the cross member. Still running a 2wd transmission as I'm still collecting parts for the 4wd setup. The thing that surprised me is my mileage increased 1.5 - 2 mpg. Yes, increased. Here are some close before and after pictures.
