What's your plan for the rear driveshaft & C-clip eliminator ?
I think we're both correct. The number I posted is the Ford "track width" (or it's something close to that) and I believe the number you posted is the WMS to WMS (Wheel Mounting Surface) dimension.

Either way, the Explorer axle is wider. But maybe not 10" wider? The YJ Wrangler factory listed "track width" is in my FSM as being 59" wide. I have transplanted several 8.8 Explorer axles into YJ Wranglers and they are 5/8" narrower (on each side, 1-1/4" overall) than the stock Dana 35 YJ Wrangler axle.

I'm not arguing, just wondering if there's really 10" of difference in width.

I've never done the research for a head-to-head comparison between the two, and my old fart memory is likely to be off a little on the exact numbers.

Correct, I listed wms-wms
The Explorer 8.8 is 10" wider than a narrow track CJ AMC 20 rear axle.
The NT AMC 20 is in 1976-1983 CJ5's and 1976-1981 CJ7's
1982-1986 CJ7's came with wide track axles.
You are correct on a near perfect fit when swapped into a YJ.
But the 8.8 isn't a great swap into a CJ, Let alone a NT CJ.

They make an adapter for the driveshaft and it has disc brakes so you really do have to worry about the c clips. Also I really don't think it's that wide because I know a few people who have a ford 8.8 in the rear of a cj5 and it's not bad at all. I'm using a Dana 30 wide track front axle and I was just trying to come close to having the same width

Good info that's good to know!

Aside from the width issue, the wheel bolt pattern difference adds to the lack of compatibility.

Now if you could find an old Lincoln Versailles 9 incher laying around, that would be worth looking at.

Except that the 9 inch has one of the lowest pinions of any axle. It makes for worse driveline angles and will drag over everything in the rocks

That's an issue but thousands of rock crawlers use em, including me. The ford 9 is a sick axle and I'll use it over a 44 or 8.8 any day. If you're gomna use 35+ tires than the LP won't matter anyway

Unless you're on an unlimited budget, then there's this.

For an unlimited budget, I'd have a high pinion 609 or portals...

Does the adapter just bolt in with no need to shorten or lengthen the drive shaft itself ?
If it has discs, then it shouldn't need an eliminator kit, as the calipers will keep the axle forme coming out if there is a failure.
The Ford Explorer 8.8 is 60.5" wide when measured WMS-WMS !
A WT AMC 20 is 54.5" WMS-WMS !
A WT Dana 30 is 56" WMS-WMS !
The 10" difference is from a NT.
There was no mention of using a WT up front.
Think what you want, Those are the specs.
To make it close to equal width, you would need 2" wheel spacers for the front.
Also as mentioned, what's the plan for the rear bolt pattern ?

For the rear bolt pattern Superior Axle and Gears makes a kit call the Super 88 Kit that changes the bolt pattern over to a 5 on 5.5 as well as upgrades the axle shafts which is what will have to be done for this axle for everything to match

Moser Engineering will also re-drill your axles to 5x5.5 for a modest fee.

so what is your grand total $$$ for this 8.8 swap up to?


I have never done a 8.8 swap, and after reading all the post the last couple of days on how much it cost to make a 8.8 work......... i will never do one, nor would I ever recommend it........lol. (I mean come on an axle out of an exploder?)

Another thing, just cus it has disc brakes..........doesn't make it a good axle. What holds the axle in on a disc brake 8.8? Is it still a c-clip? (I am just asking)

I agree that the 8.8 is not a good choice for a CJ, But a good budget axle for a YJ over the D35 joke.
It usually ends up around $1,000 including the $300- $400 cost of the 8.8, But does not include a new driveshaft if being replaced.
For that, You can buy a 1986 CJ D44 and it's a 100% direct bolt in swap.
Also, The Scout D44 is a great swap, And only needs a set of new perches.
Another option is buying a custom Currie 9" housing for $229 and scouring the junkyards for the center section.
Axles can go new or used and resplined.
Or if you can find a D60-2, But them are getting pretty scarce.
The 8.8 is a C-clip, But if it encounters a failure, The calipers will hold the axle in place to limp it out.

that's my point right there.

around here $1000 bucks will buy you an old 3/4 chevy truck with d60s and tons of other parts, then you can scrap the rest of the truck and get half your money back. Of course if full widths are not your thing (which I'd rather full width) then you have to narrow the d 60's. Just saying If I'm gonna hash out $1000; I want more to show for it than just an axle out of an exploder............

So..... your first statement holds true, 8.8 not good choice. Better options out there
