As for a response to the actual first post, stay with the 3.73's unless you're going with at least a little bigger tires than stock in the future. If you can afford it, a DTT is a much better option than the factory LSD. It also doesn't cost that much more than a trash lock considering the cost of having a rear end rebuilt. I would recommend doing all the work you plan to have done to your diff at one time because of labor charges.

He wrote "loosing my patients" instead of *patience*.
Paging Dr. SurfGuitar to the ER, Dr. SurfGuitar to the ER! We're losing patients due to an influx of seagull posts!
Sorry couldn't resist
I'll keep a closer eye on all your posts and point out all of the spelling errors....
Someone that "actually" had a bad experience with Trac-Loc, thank you for sharing real world knowledge....
His hard evidence beats your internet rumor mongering any day....
Late breaking news....I don't care.......

Go back with 3.73's if you are keeping it stock to even 245/75's
for the love of the baby christ please do not piss away the money on trash lock
I had 1 in my TJ and it was pointless to say the least
as far as I can tell did not do much more than an open diff
also dont waste your money on the power craps that people like
had 2 of them fail after the trash lock did nothing
installed a Detroit Locker ,man locker, and boy howdy
I also have an ARB up front and love it
as far as I am concerned Detroit Locker rear and Detroit true Track front is the most fool proof combo on the market that can be looked at as ok to DD on
Detroit Locker rear and ARB front ,even better but there are things that can fail
ARB front and rear is the best of both worlds but lots more to fail ,and cost a lot too

Knock yourself out. I wasn't busting your balls about spelling but rather using the wrong word; which was spelled correctly. I found it mildly comical about losing patients. First thing that came to mind was a doctor losing his /her patients. 'Twas meant in good humour.
If I was gonna be mean about it I would have got you on spelling losing wrong as well as ending every sentence with and ellipsis.

FWIW 03 Limited with off road package (TracLock) and towing package (4.10gears) and 45 RFE. Just turned 120K and it all works! Suspect it depends on how they have been kept up AND how they have they have been used/abused. (Still have original battery also and thus far no sign of dying [fingers crossed])!

You don't have 4.10's unless you added them yourself or have the 2.4 I4 being in Alaska.The towing package did not ever include lower gears on a KJ.

Agree with you... Furthermore, since it's a Limited, it can't be 2.4L I4... so if it's a gasser, can't have 4.10 from factory and be Limited at the same time... one or the other: Limited (which means 3.7L and 3.73:1) or 2.4L (which means Base or Sport and 4.10:1)
Trying to make it work... might be a Limited CRD with 5-45RFE... I don't know what gears the CRDs have...
BTW al7fi, if you have a gasser, how did you know you have a 45RFE? crawled under the Jeep? you saw it in your build sheet? or it's just based on the separated PCM and TCM?
Cheers!

Negative on the up keep and the use/abuse
Mine failed while still under factory warranty
I decided to just leave it alone because
I knew it would be getting locked
Oh yeah we had an '03 KJ just like that
Less the trash lock and you do not have
factory 4.10 gears

Not rumors my friend. I've simply been on the forum a little while and have read up on my stuff. If you could believe it there are people that know more than you. Come on surfy let's play nice.
As for the op x2 on sticking with 3.73 unless you plan to upgrade to larger tires. If so I'd do 4.10s and all other stuff you plan to put in done at once. Axle labor is mad expensive. And you don't wanna be stuck with 32" tires with 3.73s getting 13mpg. (my dilemma)

A good many people on this forum, as well as L.O.S.T. know way more than me, I've learned a lot from the two forums, but I'm by no means an expert, and never claimed to be one.
My beef with your post, and many like them is the fact that you make a quick statement condemning a certain brand/product/model without offering anything helpful to the original poster to back it up, or offer any alternatives to what he wants to do.
Had you stated that....."before you look at Trac-Loc, do a search of this site, and over at LOST, there's a lot of negative information regarding Trac-Loc. There's also other manufacturers producing limited slip for the Chrysler 8.25 axle that may be a better option"......
Now you're not just flying in, trashing a particular item of interest to the O.P., then flying away leaving him scratching his head, plus you've offered him sources to back up your claim, and the knowledge that there's alternatives to what he wants to do. This not only makes your post more palatable, it makes you look more intelligent with a true willingness to help a fellow KJ owner.
I have no doubt your true intentions were to help, but your style left you sounding like a troll....
I have....threadjacked.gif.....enough, any further discussion between us should be done via PM, and allow this thread to get back on trac-Loc....

Sorry I do not know how to do the quote thing yet (humor me, I am ancient).
However...... I am the one and only owner of this beast, and it is a 3.7 for the record.
I know it is a 45RFE, cause I have changed fluid and filters on it and also because right in front of me is the window sticker that DC put on it with every option that is on it.
I also have the 2003 Factory Service Manual and on page 3-56 it does list both the 3.73 and 4.10 ratios. I does not give what vehicles the 4.10 is used on however. On the label on the drivers side of the rear axle in addition to saying TracLock, it also lists 4.10.
Further on the aforementioned label that I removed from the window and saved, and I quote: under "Trailer Tow Group Axle Ratio 4.10". The TracLock was part of the "Off Road Group".
Sorry I did not mention the 3.7 in my post the first time.
And regardless of what anyone does say, be it fact as they know it or opinion, what I have is what it is. And I have been nothing but satisfied with it all this time and miles.
End of rant! Going on 27 straight days of measurable precipitation. Lookin for an ark!

Sounds like the perfect setup!!

For the OP, as someone else said, if you've got little money and more time a junkyard axle is the best way to go. Over here complete axles are available from a pick and pull for less than $150, which is 1/3 to 1/4 the cost of having a regear done, and even about 1/2 what it costs to buy the parts to do regear yourself if you have the know-how.
For those of you that have gone full Detroit in the rear, do you notice the "spool-release" effect when on the gas in a corner?

I don't know what you mean by "spool realease"
I have a "full Detroit" and as long as you don't drive like a complete a$$ you forget it
is there
When it is new or just installed it will take a while to learn how to drive with it but it is very predictable so after a few miles you learn

The tow package on a KJ never included 4.10 gears,I worked at a Jeep/GM dealership from '00-'03 and the only US KJ's to get 4.10's was the ones with the 2.4 I4 gas engine which was dropped for '06+.Trust me I know as I tried to order one with the 3.7 and 4.10's,was not possible unless you got the 2.4 I4 engine.

Erm, I said "spool-release". If you know what a spooled differential is, then consider what it feels like when that breaks loose and releases - this is not an uncommon phrase applied to automatic lockers. In my experience occasionally unpredictable is what I'd call an automatic locker (Detroit or otherwise) in the rear of other Jeeps with a dana 44 rear end, whether it's on road or off road, even when coming around a bend in the highway or changing lanes. I'm not trashing Detroits, since I own one, but while I can handle banging and popping all day long, a sudden release while changing lanes makes for an unhappy experience in a daily driver, add to that the generally high HOG on Libby's and that just worsens the effect. Again, I'm not slamming, just calling a duck a duck. If the 8.25 version in a Libby doesn't do that, then jolly good, but that's not a universal experience with Detroits.
Regardless, isn't the Aussie available for the 8.25 now? Unless you're planning on moving up to tires well beyond what a stock axle'd Libby is capable of hosting save yourself severals hundred fins and go with an Aussie lunchbox locker.

If you have the Trac Lok the Aussie won't do you any favors, since you'll have to swap carriers.

a spool can not break loose
it is machined so the ring gear bolts up and the shafts slide in
a spool has NO moving parts
and I had 2 "lunchbox" lockers fail
they worked fine for little while and trust me they handle like a$$ compared
to my Detroit
