Yes. For instance, you can't take the stock 4.10 gears from a Rubicon D44 housing and replace the stock 3.73 or 4.10 gears in the Ford 8.8.

The good thing is that for the most part, prices are very similar and gear/locker selection for the 8.8 is pretty good as well.

jim9006 Jeffrybomb: I see you have an í04 with an auto and 33ís . Most likely itís the 42RLE tranny. You should do some research on gear sizes if your re-gearing. Regardless of what axel you run, It will be different for that transmission due to the OD. Also a cooler should be considered as well.

I'm resurrecting this thread again. I appreciate the responses so far. Between this forum and the club I belong to, I'm learning a lot.

I found a set of stock Dana 44 Rubicon axles, but they sound a little too expensive for what they are. You've got the same response as some folks in my club.

Let me see if I'm asking this correctly: can I upgrade an 8.8 rear axle with rings and lockers the same as I would any other TJ axle? That is to say, are the mounting points the only non-standard changes I'd have to make?

Does it come with the factory locker pumps? The factory tj rubicon lockers can only take a maximum of like 6 psi before they blow the internal bladder. And its really hard finding any like new replacment pumps for them since most aftermarket pumps nowadays are way higher then 6 psi. Not to mention it will be difficult to maintain 5 psi with an aftermarket pump.

There's a substantial cost difference. Again (and as I've mentioned before), I want to do this correctly rather than waste time and money.

Thanks!

harryhood FWIW,

I was looking at either a OX, ARB or Eaton e-locker for the HP dana 30 I'm building for my jeep.

I decided against the Eaton because to many bad reviews.

I didn't see any bad reviews really for either the OX or ARB.

I decided against the ARB due to the extra cost over the OX. I also like the simplicity of the manual cable engagement on the OX.

Good to know. I'm going to edit the list down, because I definitely want lockers.

ARB Air Locker
Detroit Locker
Ox Locker
Eaton E-Locker
Auburn Ected
Dana Trac Lok

(BTW: I listed what options popped up on 4wd.com when I did a search for rear axles.)

IslandTJ Out of the list you provided, the Detroit TrueTrac is NOT a locker, it a a gear driven limited slip and will lose traction once a tire is lifted or if you rock crawl.

The Detroit Locker and Dana Trac Lok are automatic lockers which unlock when the hardware experiences a difference in speed between the inner and outer wheel. No activation required by the driver. The Detroit is a full carrier replacement, hence is a stronger unit but more costly compared to the Trac Lok (commonly referred as a lunchbox locker).

The ARB Air Locker, Ox Locker, and Eaton E-Locker are selectable lockers and require a switch mechanism to activate from an open differential to a spool. Selectivity makes this an ideal choice option for traction but more components are required for the units to operate.

The Auburn Ected is also a selectable locker but when inactive - operates as a clutch type limited slip vs. open. When activated, the unit is advertised as being "locked".

Jeffreybomb Back again after wandering around and looking through numerous axle set-ups (and hoping something would pop up on a few parts sites).

Would someone mind explaining the difference between these axle types? Benefits? Drawbacks? I know there's a number of them listed, so let me thank whoever tackles the list in advance for your time.

ARB Air Locker
Detroit Locker
Detroit True Trac
Ox Locker
Eaton E-Locker
Auburn Ected
Dana Trac Lok

I'm still considering 35" for now, but I'd like to also keep in mind that I'd like to prepare to go bigger if the components allow.

Supposedly they started back in 1934 (or at least the beginnings of what would become Superior):

Superior Axle & Gear

I wouldn't be surprised if they make a come back under new owners or something similar. It is indeed a shame.

jeepwayoflife Wow, so sad to hear. For a company that invented the "super kits" they didn't last too long. Had a great reputation as well. I guess it isn't all just about product quality... I'm glad I found a Dana 44 to replace my Dana 35 and didn't order a super 35. Thanks for the Info

Motowithy If it is out of a rubicon you will need the air pumps, and switches. Also will need to shorten the driveshaft and get a u joint adapter.

You will need the ebrake cable (not sure how it works) and be able to bleed the brake lines. As long as the axle is out of a Tj (97-06) it should fit fine.

If you think you will go to 35s then I would just save all of your "gradual" mod money until you need new tires and then do tires, rear axle, regear, steering, brakes, etc. If you decide you want lockers, its a perfect time to get them when you are regearing. However, if you decide to lock the front you will likely need chromoly axle shafts as the stock ones will be on borrowed time. And depending on how many miles you have on the front axle you can switch to better u-joints (Spicer 5-760x) at the same time. You will also need to make sure you have the necessary lift components to clear 35s (at least a 4" lift with a 1.25" body lift unless you run flat fenders and do a heavy amount of trimming like me). Also, with that much lift you will need a Slip yoke eliminator (SYE) for your transfer case, probably new driveshafts, and adjustable control arms.

doclouie Figure out what size tire you want to run long term. I prefer 33s and that is what I run with the 3 speed tranny and 4.10 gearing, but mine is a daily driver. You only want to regear once so make sure you have the axle you want. A Dana 44 out of a TJ or LJ is a direct swap and will work fine or you can go the Superior Super 35 route. Figure that out and then regear as needed. 33s and the auto tranny are ideal at 4.10 gearing although 3.73 is not too bad either.
03-20-2013 05:35 PM
Jeffreybomb I found a graph (and of course I'm having a hard time trying to find it again) that compares gear ratio to tire size and shows their RPMs. The graph was color-coded to show optimal gear and tire configurations.

That said, if I find a used axle that's "bolt in," does that essentially mean I can run it without having to make further modifications to CVs or transfer cases, et al? As always, I want to make sure I'm doing this right, but it would really help me in the wallet if I can do the build gradually versus dumping everything in at once.
03-20-2013 05:00 PM
5spdftw Regearing is tough when you are not sure what size you will run. I think 4.10 is right for the 3 speed auto on 33s. Don't take my word for it though, I have 35s, a 5 speed manual, and 4.88s. I've also never been on 33s so everything I can say about them is speculation and stuff I've heard or read.

Good call. Sounds like I'll have to keep my eyes open on a wide range of sites.

When the weather gets warm, it's easier to take mass transit here in Chicago, so the TJ moves away from being a DD. I think I'm about middle of the road between DD and "weekend toy."

I'm still trying all kinds of different wheeling. I think rock crawling and hill climbs are some of my faves. Don't really know what fire roads are.

I have an automatic transmission.
