I will never run a drop in in the rear again, just to much slop for me.
Agree, i love how tight my truck is with the rear spooled

What I would do.
Weld the diff of the Fj40. I could DD mine with a welded rear. I rather drive my powerstroke tho (Powerwindors =) and ac and radio lol )
Leave the front axle alone. Just swap rear with 60 40. weld the 60s if you wheel with it more
ARB rear, detroit front
Steers MUCH easier
The rear of my 80 (the grocery getter) is welded and I haven't had any issues due to weight, but the 80 axle is a different animal than the 60 rear axle....
I would weld the rear of the 60, put the detroit in the front of the 60.... Then...
Find a full floater with disks out of a 80 and swap it into the rear of your 60....
By the time you break the welded rear 60 axle, you can then put the 80 axle under it.....
The 40, I would weld it and call it a day. I ran my mudder/daily driver with the rear end welded with 35's years ago. Just don't drive like a nut and you will be fine....
As others have said, just don't weld the clips that hold the axle shafts in.
good enough for me.
I guess next time i get into the front of the 60 or change the diff fluid ill move the detroit from back of 60 to front front diff will be welded and moved out back and the aussie from the front of the 60 will go to the back of the 40.
that is if i dont for some reason get into the 40 first and weld it up.
wow, that's a LOT of freaking work
At least he gets to work in a controlled emvironment, the last time I did a diff shell game it was no fun at all.wow, that's a LOT of freaking work
My experience would say if your gonna weld a diff weld the front on a selectable rig. Ive run spooled rear ends and hate it. Now I run an aussie and love it even in the snow and ice. An aussie in the rear and a lincoln up front done the "right" way is in my humble opinion the way to go unless you've got lotso bucks
