Front diff questions
I have a 1993 F250 Super Cab with a 7.3l non turbo. It's 4 wheel drive with IFS. I would like to convert it to a solid front axle. My question is are the front ends the same on the f350 with dual wheel? Can I just change the hubs, brake rotors, etc..? Also are the five speeds that are bolted up to the 460 the same as the 7.3? Has anyone done the solid axle swap / 5 speed conversion? Thanks

Also, Does anyone know if the driveshafts will interchange going from an auto to a 5 speed? It's my daily driver so I'm trying to collect all the parts before I attempt any conversions to save on down time if possible....lol

It's a good amount of work. May want to consider just finding the truck you want vs building.

driveshaft
I'm pretty sure the 5 spd driveshaft is about 4" longer than the automatic driveshaft.I am certain that the cross member that the trans mounts to will have to be moved foreward in the frame also. It's bolted in and the holes are all pre punched.

You want the springs from the F350 with the axle, as well as the spring plates with the shock mount. The IFS springs are a much higher spring rate, and will be way to stiff with a solid axle...

king pins
the 60 size "king pin" bearing style front end is the one I used in my swap. The "king pins" in that set up are actually cup, cone, & rollers. They are virtually indestructible. I used positive arch springs that came out of the '82 f 350 donor that I harvested the axle from, I don't think they were stock. Make sure you get the stabilizer link and steering linkage (tie rods & ends). The pitman arm on your 250 steering box should work. I was told I would have to cut the cross member but I didn't, probably because the springs lifted it about 3". It should mount to your stock neg. arch springs without much ride height change. I did the work at my bud's shop, I'm not a mechanic, we were all shocked at how simple it was. A little knowhow and the right gear and you should be able to pull it off in a weekend no problem. The tranny change is a different story however. I had my truck completely disassembled and really wanted to put a 5 gear I had on hand in it, but after much deliberation I stuck with the auto to avoid the tremendous amount of work that is required in the cab. Its not impossible but you probably would want to pick up a beater to run around in while your down.

83capril,
I was reading your reply and has a question. You wrote " I believe the D60 uses a different (good?) on the t case and axle" I'm assuming that's a typo or auto correct? I don't mean to sound dumb but what did you mean?
Thank you all for the info. I'm gonna do a lot more research before I tear into anything!
