Would this be a good Axle Setup?

blackout00 · 12-04-2007, 07:35 PM

Was just seeking some advice on my 2000 6cyl TJ Sport Axles. I am currently running the stock Dana 30 in the front and the Dana 35 in the rear. I am looking at upgrading to the OX Selectable locker in the rear with Alloy USA upgraded axels and putting an Aussie in the front. I do mostly trails with some rocky climbs. I by no means do heavy rock crawling. I just want something that will allow me to have a locking rear when the going gets a little tougher. Also what gears are currently in my TJ? I think that they are 307's?? I assume I would swap some gears out while I was doing things as well. The current lift is a 3" Teraflex with 33's. Thanks for all your help in advance!

4.56 gears and 30 spline axles with the OX would be a good set up.

A couple of things...

Please fill out your profile. What trans do you have?

Not to be rude but it's axle, not axel.

Second, many folks will suggest you not put any money into a D35. A D35 super kit will give you more reliability but I think I'd bite the bullet and pick up a D44.

I think I'd buy a Lock-Right for the front D30, not an Aussie; keep the money in the USA. Of course this was just said by a guy that has ARB's, front and rear. The Lock-Right (and Aussie) is awesome in the front; on the street you won't even know it's there.

Yes, 4.56 gears with 33's, unless you have the 3-speed auto. Oh, what the heck, 4.56 even if you do have the 3-speed auto.

There may be a factory tag on your diff covers that will tell you the stock gear ratio that came with your Jeep, worth a look.

That will work well with moderate wheeling and 33's.

You definitely should not install a locker into your rear Dana 35c axle, it's not strong enough to support a locker and 35" tires. Your front Dana 30 is ok to lock and run 35" tires but wait until you install some sort of a stronger upgrade in the rear before installing a rear locker. Like a Super 35, Dana 44, Ford 8.8, etc.

Unless the rear Alloy USA axleshafts you are talking about are 30 spline and the Ox Locker is the matching 30 spline version, then you're good to go with a rear locker in your Dana 35c.

I think I'd buy a LocRite for the front D30, not an Aussie; keep the money in the USA. Of course this was just said by a guy that has ARB's, front and rear. The LocRite (and Aussie) is awesome in the front; on the street you won't even know it's there.

Sorry on the spelling!! Brainfart...haha. How much is a rear Dana 44? I thought that a Super 35 Rear was a good setup for what I was looking at doing. What all is considered to be in a Dana 35 Rear?? Can someone please elaborate on the Advantages of a Super 35 versus a D44? Sorry this is all a new thing to me. I am correct that thinking the LocRite is a good option for the front? And do I regear the front and rear? Sorry for the dumb questions. Been searching and just need some direct answers. Thanks

kd4yor · 12-04-2007, 07:56 PM

I'm going to get flamed for this....
I see no advantage of a TJ D44 over a TJ Super 35. The 35 actually has a thicker pinion shaft, but smaller ring gear. your limited in gearing to 4.88 with the 35. But 4.56 works well with 33's and 35's IMHO.
Yes you will need to geatr the f&R to use 4wd.

A built D44 is around $2K. But, by the time you buy the OX locker for the D35, plus upgraded axles and gears, you'll be into a fair chunk of change anyway. Like kd4yor says, there are many folks happily running Super 35's with out fail, even on 35's - let alone 33's. You'll be fine with that, if you choose. As also stated, yes, both the front and rear would need to be re-geared at the same time.

A super 35 kit consists of a full case locker (carrier replacement) such as ARB, Detroit, OX, and has a larger spline count to allow the use of upgraded axles.

Thanks so much. So something like this would work in the rear? http://www.quadratec.com/products/16100_450.htm

And then I would regear the front and rear to 4.56. What would this do to my gas mileage?

Greg_Volkman · 12-04-2007, 08:14 PM

i wouldn't spend any money on a Dana 35. period.

kd4yor · 12-04-2007, 08:15 PM

that would be a sweet set up with an Aussie up fromt (I don't like the lockright). I can't comment on gas mileage cause I track hours to the gallon.

The Dana 44's housing (pumpkin) is FAR stronger than the Dana 35c's housing which reduces axle housing flex.

Dana 35c pinion shaft diameter: 1.16"
Dana 44 pinion shaft diameter: 1.31"

You are correct that the Dana 44's ring gear is bigger.

I will all day long.
When I need to build one every few years someone who doesn't trust it will give me a nice used axle for nearly free.

You are correct however that the Dana 44's ring gear is bigger.

tube wall thickness is the same...how is the 44 stronger?

taken from JF sticky on stock axles

Dana 35C 1997-2006
* Standard rear axle used on all TJs except the Rubicon model
* Stock gear ratio options = 3.07, 3.55, 3.73, 4.10
* Carrier break = 3.31 / 3.55
* Optional Trac-Lok limited slip differential
* Ring gear diameter = 7.5625"
* Ring gear bolts = (8) 3/8 x 24 RH - NOTE: 7/16" used on later model TJs
* Low pinion
* Pinion shaft diameter = 1.406"
* Pinion shaft spline count = 26
* Axle shaft diameter = 1.16"
* Axle shaft spline count = 27
* WMS-WMS = approximately 60.5"
* 5 on 4.5" bolt pattern

Dana 44 1997-2006
* Optional rear axle used on 6 cyl models except the Rubicon model
* Stock gear ratio options - 3.55 (97 only), 3.73
* Carrier Break = 3.73/3.92
* Standard Trac-Lok limited slip differential on early model TJs / Optional on later model TJs
* Ring gear diameter = 8.5"
* Ring gear bolts = (10) 3/8 x 24 RH - Note: 7/16" used on later model TJs
* Low pinion
* Pinion shaft diameter = 1.376"
* Pinion shaft spline count = 26
* Axle shaft diameter = 1.30"
* Axle shaft spline count = 30
* WMS-WMS = approximately 60.5"
* 5 on 4.5" bolt pattern

Jerry, I think you were refering to axle shaft dia. This all changes with 30 spline axles.

Yep, that looks good. With the gears, your engine will be back in it's normal power range. Gas mileage may even improve but I can't promise you. The increased power after the re-gear will put a smile on your face though.

What is the issue with the Lock-Right? I thought they (Lock-Right and Aussie) were equivalent?
