Dana 35 and 30 ratio question

Put the Jeep into 4wd and the transmission into neutral. Roll the Jeep by hand and see if it goes anywhere.
Don’t. You will break it. If you do try it anyway, please report what you break. Its always helpful to know where the fuse link is.
Seriously? Maybe you can run 225's in back and 33's up front.
Right?! There is probably a tire size that makes it work ok. And I guess if the surface is slippery enough then it might not grenade.
OR use an NP203 transfer case, which has a differential within it that you can lock/unlock.
See, lots of ways to make mismatched gear ratios work!
Why?
There's plenty of them with 3.73 gears.
Why?
Couldn’t find one with it but for now just won’t use 4wd I’ll re gear it soon
Found a good deal on that rear end and went with it
your going to have to replace your carrier too, to go from 3.07 to 3.73. I believe the break is at 3.55 on the 3.07
Can the front end just be re geared to 3.07? Found a new gear set for abt 100
Don’t care if it loose a little speed just need a working 4wd for snow
I don't think it can without a new carrier either way. The carrier is different and you can't just swap gear sets either way. You need to find a 373 rear or a 307 front end. If you put it in 4wd now it will destroy your transfer case.
Regearing is WAY more expensive than a used axle. You DO NOT want 3.07 gears.
I see your 17 and I was long ago. but understand this isn't a just remove one and bolt on the new one deal ! there's a lot involved in changing out a ring and pinion set. and seeing how you didn't know not to mismatch a 3.07 and 3.73 I am doubtful you currently have the knowledge to do it. like I said I know I was 17 too. and thought things would be simple, like putting a 302 in a 71 Bronco with a 6 cyl. after many days of cussin and fightin I gave up this was in the early 80's before the internet !
I agree with Boog (for once)
As a 3.07 user, you DO NOT want 3.07 gears.
Im stuck to 235’s all round because even the stock 30” was bogging down.
High school yearbook pic or it never happened. Braces and a mullet are acceptable.
That could be a whole 'nother thread for a bunch of us geezers. Go ahead and start it, Boog.

I'm in! I never took high school pictures.

So far the 3.07 has treated me decent on 31s besides the speedometer is all kinds of wonky it’s off by 5mh till you hit “70” then I’m somehow going 87
But i planned on replacing the spider gears in my Dana 44 slapping that back in there and keeping the 35 as a spare
