Auburn gear locker?
 
I'm thinking about using an Auburn gear Ected Max locker in the rear dana 44 of my 2003 TJ and an Aussie locker in the front dana 30.
Anybody that's done this or something similar, would be great to hear the good and bad.
I'm sticking with 31" tires for a while and everything else is stock on the jeep save for the shocks.
Thanks!
Brian

Bump...

I had an aussie front and rear. Both performed great. Easy install. I understand the aubern locker to be a similar easy install. The front locker was not so fun on the highway, in 4wd, in the Colorado snow. That doesn't look like that'll be a problem for you though.

IMM 11-15-2013 06:18 PM

I'd really like to run the Ected front and rear, but not sure if the limited slip up front would matter since the fronts not engaged...wonder how the LS in the front would work in snow/ice if I was in 4wd?

IMM 11-16-2013 03:41 PM

Has anyone used the ected up front and out back?

Jerry Bransford 11-16-2013 03:48 PM

I'm not a fan of an ECTED which is clutch based. Go onto Pirate 4x4 where there are complaints of them slipping when doing a difficult section of a trail which can be attributed to its use of a clutch pack. For around the same cost, I'd look into an Eaton E-Locker which locks up electrically, I know a number of wheelers who have had good luck with that particular lower-cost selectable locker.

IMM 11-16-2013 07:18 PM

If I'm reading this right, you go from a clutchpack to solid axle via the magnet locking the clutchpack solid:Leading Manufacturer of Traction Enchancing Differentials & Planetary Drives - Auburn Gear

They claim it goes solid anyway...would really like to hear from someone that's used them.
I would think they should be plenty strong with 31's and light wrangler.

Is this the Elocker? EGerodisc Differentials

Here's the Eaton E-Locker... ELocker Differentials

Maybe but I don't actually remember that name... which means nothing since I can barely remember what I had for dinner Friday night lol.

He was a good friend of mine. He offroaded out of san diego...had a nice cj. He was a border patrol agent who lost his life coming home from work Sept. 7 2007. Just wondered if you might have known him.

Anyway, I think I might stick with the lsd in the rear for now, and go with an lsd up front. It looks like Detroit doesn't make a true trac for the dana 30? What would you recommend?
And is the high pinion 30 worth the swap? My father in law has one he'll give me.
Thanks!!

Jerry Bransford 11-17-2013 01:33 PM

Sorry to read about your friend.

Yes for sure there is a Detroit Truetrac made for the Dana 30. A HP D30 is a very good axle to install if you wheel in conditions where its higher pinion shaft position would make a difference. Plus its ring & pinion gears are run in a direction that makes them a little stronger, it's a very good upgrade for wheeling in more difficult conditions.

I can say that if you wheel up in the Big Bear or desert areas, you'd gain far more benefit from a true locker than you would a limited slip differential. I used to run front and rear Detroit Truetracs but replaced them both with lockers which gave a DRAMATIC improvement to how easily the Jeep was able to make it through far more difficult trail conditions. LSDs are more for slick street conditions like where it snows/gets icy, lockers are much (!) better for offroading on the trails common in SOCAL.

Looks like I will search for a good used Detroit locker and go with the HP 30. I found some aftermarket axles and shafts for 200.00 so looks like all I need is a set of 3.73 gears and I'm good to go! Thank you!

Jerry Bransford 11-17-2013 05:04 PM

I think you'll love the Detroit Locker, I sure did mine.

However, if you install a Detroit Locker made for that 3.73 ratio, you'll need to use a thick-cut ring gear if you ever go to a lower ratio like 4.56 or 4.88. Detroit Lockers are made in two versions for the Dana 44... for 3.73 and higher ratio like 3.07 gears, or 3.92 and lower ratio gears like 4.56 or 4.88.

Hey guys. Got a question. Went riding today with some guys off the forum in south alabama today. This forum is awesome!! After riding through a few places where everyone else had 4.0 and I have a 2.5 (the little engine that could) I found I can go anywhere they can but one main thing is needed! LOCKERS!! A couple of times it took me a few attempts where it only took most other people once. My question is if the differential locker is the same in the front of my jeep as the rear. Meaning if I was to order a differential for the rear I would need to order one for the front and they could both be changed at the same time with the same part. I saw where Detroit lockers are the best thing just want to know witch Detroit locker is the best and if the same one will do both the front and rear. Any input is greatly appreciated!! Thanks!

Jerry Bransford 11-17-2013 06:13 PM

Lockers need to be different models for your front Dana 30 and rear Dana 35 axles. However, I would only lock the front Dana 30 since your stock rear Dana 35 is not strong enough to remain reliable after installing a locker into it.

Detroit Lockers are awesome in the right axles that are strong enough for them, which does not include either of your axles.

For your front axle, three good choices include the Aussie, Lockright, or No-Slip with my personal pick of those three being the No-Slip. That is because the Aussie and Lockright will click/make a ratcheting sound during turns on the street when you're in 2wd. The No-Slip is silent, at least it is to my ears. But if you don't mind some front-axle clicking, by all means go for an Aussie or Lockright locker. All three of these lockers are what is called a "lunchbox" locker which means it is simple to install and goes into your Dana 30's differential after removing the spider gears.

The Detroit Locker you asked about is a GREAT locker but it isn't good in your front Dana 30 axle which flexes a bit too much for the Detroit Locker. The Detroit Locker is a superb locker for stronger axles like the Dana 44, Dana 60, Ford 9", Ford 8.8, etc.

So for now, I'd lock the front axle with a lunchbox locker and leave the rear axle alone until you can upgrade it with stronger axle shafts which is the main weak point of your rear Dana 35c axle. :)

What about the 30? That's the axle I'm working on for now. I have a lsd that came from the factory in my sahara in the rear, and it works OK but with a DL up front I'm thinking that's the best bet for now.

On another note...is there a thread about rebuilding the front end and what brand of bushings, tierod and ends, etc...? I figure moog is the best but would like to hear what other guys have done.
My TJ only has 74,000 original miles but I figure it can't hurt to freshen everything up.
Thanks again for all the help!
Brian

IMM 11-17-2013 06:17 PM

What about if I go to aftermarket axles and shafts? Is the DL a good option for the 30 then?

Jerry Bransford 11-17-2013 06:24 PM

The Detroit Locker is not a good choice for the D30 which flexes too much for it, not even if you installed aftermarket shafts.

If you went with an aftermarket non-Dana 30 axle then yep the Detroit Locker would be fine up front. Even the Rubicon Dana 44 up front flexes too much for a Detroit Locker since the Rubicon's version of the Dana 44 uses all Dana 30 components except for the center Dana 44 pumpkin, gears, and inner axle shafts.

So looks like the truetrac would be best up front. How about that lsd that comes factory...is the truetrac much better out back than the factory unit? Are the aftermarket axles and shaft a waste of $$$ on the 30?
Bet you burn up your keyboard Jerry!

Jerry Bransford 11-17-2013 06:46 PM

Why did you suddenly switch from interest in a front locker to a Detroit Truetrac limited slip differential for the front axle? :confused: For our SOCAL trails, a locker is much better & why I gave you three lunchbox locker suggestions for your front Dana 30.

I thought you were talking to the other guy! So you think the NO-slip is what should be up front? Much better than the truetrac or marginally better?
And since we're talking so much...;-) what do you think about this:Rusty's Tie Rod - HD Replacement (XJ,TJ, ZJ) - Tie Rods & Drag Links - Jeep Steering

Maybe I should just buy the beer (or Kesslers) and talk in person sometime...LOL!

Jerry Bransford 11-17-2013 07:02 PM

It applies to anyone with a D30 up front but yes I got a little out of sync there didn't I lol.

On our SOCAL trails, LSDs are next to worthless which is why I replaced my f/r Detroit Truetracs with f/r lockers many years ago which made, without exaggeration, a night and day difference in how well my TJ performed offroad. On a trail uneven enough to lift a tire up off the ground as is common around here, a LSD is useless/of no help.

Any lunchbox locker up front would be fine... but if you have the budget, a selectable locker like an ARB (best), E-Locker, etc. is even better since it can get really hard to turn in the right trail conditions with an automatic locker like one of the lunchbox lockers.

I'm not a real fan of Rusty's but that tie rod looks ok for the price.

I'm a single-malt scotch guy but that Kesslers whiskey sounds like something good to sample around the campfire some night after a good day of wheeling. :D

Some times I feel like I just follow Jerry around the TJ section learning and asking...


I have a detroit locker in my rear D44. Ive been putting off a regear due to expense and not wanting to have to change my locker making it twice as much.

I can keep my current Detroit which is good up to 3.73(numerically speaking) when I go to 4.88s if I get thick cut gears? Did I read that right?

99 GOLD TJ 11-17-2013 07:59 PM

Yeah sorry I seemed to have jumped into the middle if y'all's converted station. Still new to the forum. So I will need to upgrade my axels and get a Detroit locker so that all four wheels will spin no matter what! Thank you for your input! Sorry to have messed up and got you confused guys. Thanks again!
