Is a 4wd rear axle the same width as the 2wds?
Reason: Trying to source a limited slip in a 2wd is scarce. 4wd diffs are everywhere and affordable.
Thanks.

For 72-93 trucks yes 2wd and 4wd are same width.
But, there were changes to lug patterns, diff side gears and c clips in the half tons.
3/4 and 1 ton stuff is a book worth of changes but complete assembly swaps have less headaches.
Also, 4wd did not include limited slip.
What are you working on?

It's a 2wd half-ton, '85. For some reason it has the 5.5 bp, I thought it should be 4.5?
D100 slant six 833od, so not sure what yoke it will have? Do the 9 1/4 and down all use the same u-joint/yoke?

Rock Auto is showing the same u-joint for 4wd as 2wd so, must be in the clear.
Good deal, should be an easy swap.

I have a Dana 60 from my 1996 2500 2WD. It has no internals now as I lost a carrier bearing. I ended up buying a complete Dana 70 and out of a V10 truck in a junkyard, they seem to be MUCH easier to find then a 60. It was also a cheaper alternative then buying the bearing and new gears for the 60. The problem is the differences in the shock mounts, brakes, and lots of other changes from first gen to second gen. I have two Dana 70's for first gen trucks too.

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.

IIRC, rear springs went from 2 1/2"x52" to 3"x60" in 1994? Even if you found an 8.75 (last used in 1974?) diff I think spring perches would be hurdle #1, then shock mounts and driveshaft, can't recall if it needs to be longer or shorter. There's nothing wrong with the 9.25", I'd keep it.

To be honest with you Wyldebill, I don't know who came up with "First Gen" to label this era of truck. You'd think a First Gen Ram/Dodge would be something from the early 30's.

Probably started by GM guys, that's who I hear it from. A lot of em around here drive Dodge trucks nowadays but are still Chevy guys at heart. See an early '80s two wheel drive short bed and they say "Dude! You see that first gen back there?" Me and any other Mopar guys I know call em '72-'93s.

It got started with the Cummins guys. The "first gen" Cummins was the 89-93 body with the VE pump.
2nd gen is 94-01(?) Body, 3rd gen is 02-08 etc
Prior to that it was just Dodge truck.
