Just out of curiosity. Say I wanted to swap out my rear axle with one from an XJ (D35) in order to get rear disks on my 83 Eagle. As D35 with 2.35 gears are kinda rare, can I swap the 2.35 gears from my current axle into the newer carrier if I get one with the proper carrier break (3.31 and below)?
Thanks,
I think the XJ axle is a Chrysler corporate axle. OEM Eagle axles are Dana products. The internal parts are not interchangeable between the two. :eagle:
They used Both:
1984–1989: Dana 35, non c-clip, with anti-lock braking system (ABS) or non-ABS.
1987–1991: Dana 44, models w/tow package only, 30-spline axleshafts, non-abs.
1990–1996: Dana 35, c-clip, ABS or non-ABS.
1997–2001: Dana 35, c-clip, ABS.
1991–1996: Chrysler 8.25", c-clip, non-ABS, 27-spline axleshafts.
Late 1996–2001: Chrysler 8.25", c-clip, non-ABS, 29-spline axleshafts.
I don't have any experience doing it, but I don't see why it wouldn't work. Dana 35 gears are the same as the AMC 15 gears. You might be the first to try. You probably know this, but XJ's never came with rear disc. You have to get the rear disc parts form a ZJ and mount them to the XJ axle.

Right. But first step would be able to figure out if I can use the 2.35 gears in a new axle. I've looked around at a bunch of places that sell ring and pinions and no one has 2.35 gears for a D35.
Aren't the 2.35's the odd ball gearing that only fits in the 2.35 housing? You might want check these folks out: http://www.ebay.com/itm/1982-87-AMC-JEEP-DANA-35-RING-PINION-2-35-1-GEAR-RATIO-7-1-2-DIA-17-40-TOOTH-/390642959037
It's only the front that was oddball and only 80-82. Frankly, I would welcome the opportunity to switch to at least 2.72 gears.

I'm not planning on swapping my front axle out so 2.35 gears in the front are going to stay. My purpose for this is to get disk brakes in the rear of my Eagle.

I am sorry if this is dumb, but don't your front and rear axles need to be the same ratio?

He wants to install a Dana 35 rear from a Cherokee and install his 2.35 gears from the AMC 15 into the D35.

Correct Eaglefreek. Want the D35 in there in preps for later addition of rear disks.
You need a C lip one then because the backing plates, etc changed to allow for Mopar brakes instead of AMC after '91.
Update on this: At the suggestion of a well known Jeep guy (have you heard of the "Jeep Owners Bible"? Its that guy), I did some more looking at the parts used in a AMC 15 and Dana 35. Differential bearings, race's, etc are all the same part number. Pinion Bearings are the same, Pinion seals are different (physically the ID and OD are just slightly different and that's down in the 1000ths). Ring gears are the same size and I'm still trying to find info on the pinion dimensions of the AMC 15 pinion. Axle bearings are different sizes but that's easy to account for as the D35 has thicker axles than the AMC 15. I sent him some drawings from the FSM of the AMC 15 that he requested. Will see if I can get anywhere with this.
Jeep D35 from an XJ bolts in and you just need to swap the shock mounts to make it work.

Correct, Carnuck, but my question is concerning the 2.35 ring and pinion gear in my AMC 15 and will it work in the D35 axle? I don't want to swap out my front axle.

There are 2 Dana 35 carriers, 2.35-3.31 and 3.54-4.88. So as long as you have the right carrier, I don't see why it won't work.

My thought to and yes, as long as I got the correct carrier, I should be good to go. I've researched all the part numbers of the internals of a AMC 15 and D35 (same bearings for both carrier and pinion, pinion seal is different though) but I just don't want to end up with a D35 that I cant use. I'm on a budget and would like to get answers before I tackle this.
The D35 pinion seal is just a bit tougher than the M15 to handle offroad use due to the excess dirt that on-road cars don't see. They learned from having to change so many on the Eagles under warranty and Dana did the upgrade when they redid the axle for Jeep use.
If I had a few more dollars to spend on my projects, I would take a Model 20 from a Grand Wagoneer or narrow track Cherokee/Wagoneer and have new shafts made with the correct bolt pattern and offset to use XJ 10" drums or possibly find 11". The stock ratios kind of suck though. 3.31 or 2.72 was most common after '80.

Unfortunately, those Wagoneers have 60" width axles and are a little too wide. Might have to move the spring perches to maybe? Until I can get a definite answer going to keep stock axle in place.
They are within an inch and a half, which could be cut back with shorter axles (at the drum). In fact, they are commonly run in offroad XJs due to being so close in width.
If I'm not mistaken, the front axle on the Eagle is a bit wider, like 1.5-2", than the rear. Setting that axle in would even them out a tad IMO.
Now that I read that the XJ rear D35 just has to have the spring perches swapped, a plan comes to mind for me :)

You don't have to touch the spring perches on Cherokee rears. It's the shock mounts you may want to swap.
8.25 has thicker tubes but the same spring pad spacing too. I still need to do the shock mounts on mine but I'm waiting till I'm not dizzy so I can swap my rad. Comanche, Wrangler and Grand Wagoneer axles (6 bolt wheels) need spring pads done.
So with my stock axle with the "J" stamped on it, I could swap that out for a D35 and take the guts from mine and slap into it? (with the spring perch change)
Yup. Double check the numbers on the carrier. Actually, the spring perch on XJ diffs is the same. You need to swap the shock mounts. I used a sawzall to take old ones off a bent diff for mine but haven't welded them on yet.
