If you are running 5:13 gears in a Ford 8.8, what kind of axle do you want to substitute in place of the D30 to accommodate the same 5:13 ratio?
-
44. It would seem kind of dumb to go with a 9" or a 60.

A 44 would be just fine. But say I'm running 35s and want to get the same drive-ability as when I had 4:88s and 31s.
I know 5:13s and axles -- 8.8 rear, D44 front -- that could handle those gears certainly wouldn't hurt.
But is 5:13 low enough to get the 4:88/31s performance, but on 35s? My guess is that it'd be pretty close.
But I'd still be interested in at least a rear end (just the rear for now) that, in the long run could maybe handle lower than 5:13s.
-----------
Edit: I played around with the grimmjeeper link and it looks like I'd need axles that could handle something around "5.50" (or nearest ratio sold) to get the same 4:88/31s performance.

I am happy with my 5.38's and 35's. On 37's it was pretty OK too.
Find some Waggy D44's. You can go as low as 5.86.

What kind of rear-end are you using?

Do you already have the 8.8 set up? If not, consider d44's front and rear with 5.38 gears. I run 5.38 and 35" tires onroad, 36" to the trail and offroad. It's a great ratio for this size tire. You can run a Waggy front d44 and Rodeo rear d44 and get matching 6-lug axles with 4whl disc brakes.

I know a guy who runs 5.86 with 35s on his 4banger YJ. It's too low, he falls behind on the highway. So 5.38 would pretty much be the practical limit with 35s.
-
So, I'd need Dana 44s front and rear? I'm surprised the 44 can hold lower ratios than the 8.8.
But I know I'll go 4:88 for the 31s and like that. Then as soon as I change to 35s in a few years, I'll be dying for the 5.38 ratio. So, might as well get the axles that will handle that ratio upfront.
-
Not sure how low you can go with the 8.8 but you can go as deep as 5.89 in the 44. The 'Zu and Waggy d44's are a good combo, I picked up a 2nd set to go in my MJ.
-
5.89's with the overdrive worked fine for me. Could still hit 75 on a good day. Usually around 70mph. Now I have no overdrive... :(

I was under the impression the 44s were all 5 lug. Or maybe I'm confusing the 8.8 specs with the 44's. Was kind of hoping any change in the rear axle would still incorporate the same 5 lug setup -- I'm still running the stock steel wheels on 31s and wanted to hold off changing wheels until the next tire change.
Bounty Hunter, is the Rodeo D44 the only 44 out there with discs other than the TJ Rubicon "44s" ?

ZJ has discs as well but just like the Rubi it's a D44 center with D35 outers (i got a pair of rear discs for my D35 off a ZJ) - i hope i remember correctly and not mixing them up.
-
I may end up settling for a rear D44 with drums and the 5 lugs. Would prefer rear discs, but it's done ok with the drums on the D35 and an EBC disc/pad and steel line upgrade on the front.
For larger tires, though, the brakes will probably need a larger master cylinder swap or something else I figure
-
Don't mention the ZJ, it's a d44a with an aluminum center section, very problematic axle. The only thing the ZJ is good for is to pull the disc brake parts off for install on better axles.
You can't upgrade the front axle unless you're willing to go with different wheels, 5x5.5" is the smallest lug pattern a d44 hub will fit through.
The Rodeo rear d44 is the only d44 with rear discs I know of that's a decent swap into a jeep. Very plentiful in the junkyards.
A front d44 is well worth it, for the larger brakes, great histeer options, locking hubs, and serviceable bearings.

hmm, sure didn't look like aluminum to me, either way still has the weak tubes so not much of an upgrade anyway.

Most D44 axle shafts, especially XJ/TJ can be bought with 5 on 4.5 and 5 on 5.5 so you can change the pattern to match once you get a D44 up front.
-
I run an 8.8 with 5.13's with Spidertrax spacer/adapters that pushed it out and changed BP to match my swapped in HPD44 for the front (Albeit, my front's a '76 F150 D44 and i had to have it shortened a bit so i could use rubicon shafts....
In any event, my tires are 37's. I wish i would have went lower. I think 5.38's would have been ideal. Ah well.. You learn. I don't do allot of driving so it's not a big issue.
-
So do any of you guys have any tips on places to score a rear Wagoneer D44 for a reasonable price?
There's a boneyard in the San Bernadino area that specializes in Jeeps and that I've visited once way back when due to emmissions-related issues -- I needed to pick up a stock airbox for CARB testing.
But as it stands now, I'm going to be forced in to phoning and/or emailing a bunch of yards with inquiries about a rear Wagonner D44.
btw what's the price range typically for an old rear D44 from a pick-n-pull type place?
-
$100-$200 around here.
Why not grab a d44 from a Rodeo or Passport? Much more plentiful than old AMC iron.

So Bounty Hunter, if I'm looking at rear axles from Rodeo/Passports and find one from a '93-'04, it's definitely going to be a D44, right? I read the year range is '93-'04 http://en.wikipedia.org/wiki/Dana_44.
I was paging through salvaged axles for sale and most of the Rodeo/Passport rear ads for those model years give you the gear ratio but that's about it. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=190437663931&viewitem=&_trkparms=algo%3DLVI%26its%3DI%26otn%3D2&category=33731#ht_2299wt_939
I'm probably going to buy one locally. But I just didn't want to end up with a Rodeo axle from '93-'04 that was from the one model year when Isuzu got a great deal on ultra-light, Chinese-made rear ends with Balsa wood housings or something.

No, they used another axle besides the d44 and I believe that axle had drum brakes. The axle width also varied over the years so measure before you buy. I believe my mid-90's axle is 59"ish, and late '90s they got wider like 63" IIRC. The two common gear ratios available were 4.11 and 4.30, both thick gears on a tall ratio carrier.

Ok, I'll look out for that. Are you running 6 lug/5.5 wheels or did you set yours up to run 5 lug wheels?
-
I run 6-lug wheels, several sets as they're very common. Chevrolet 4wd and a bunch of imports use this wheel pattern.
