A while back I ask here about changing the differential gear ratio in my
2002 TJ, 4.0 (had installed a 4" lift and 33" tires, need to change gear
ratio)

It has been a while since messed with this , got married in there somewhere,
and also lost the thread. Anyway I do remember that basically the replies
were that I would have to change the carrier because the factory carrier in
my wrangler would not take 4.11 .

Anyway, a lot changed around here about the same time and I am just now
getting back around to messing with this.

Anyone know what would be easier / cheaper / or even possible :

(1) Find a wrecked 03-0? Ruby - will the Dana 44 bolt into my 02 Wrangler
without mods ?
(2) Will the carrier for a 97-0? 2.5/2.4L - Manual ( the manuals are 4.11 I
believe) work as the carrier I need ?
(3) Can I use the ring / pinion / carrier out of the manual 4 bangers ? or
(4) Find a wrecked 97-0? 4 banger TJ with Manual trans (4.11 gears) - will
the axles bolt up under my TJ without mods ?

Is there another , non crazy expensive, way to do it that I missed ?

It's going to be the wife's daily driver now because she drives a lot less
than I do and she loves driving it. I already suggested removing the lift
and tires ( I still have all the factory stuff in the garage) and she
informed me that wasn't an option... So that isn't an option...

Thanks in advance for any suggestions or info.

You have the 3.07, apparently. I think the cutoff is 3.55 and (numerically)
lower requires one type of carrier, 3.73 and higher requires another.

You could, you also would need the air pump and electrics for the lockers if
you wanted to use them. It should bolt right up otherwise but probably not
your least expensive choice.

Only if you have the Dana 35 rear, which you probably do if you don't have
the 3.73 gears. The Dana 44 carrier won't fit in a Dana 35.

They should. This would be the "easiest" route, assuming the junkyard axles
are in good shape, and may even be cheaper than regearing depending on what
you pay for the axle assemblies.

Depends on your definition of "non-crazy expensive." Most of the expense of
re-gearing is in labor, it's a very exacting and labor-intensive job, best
left to professionals or at the very least someone with lots of experience
in changing out diffs. Even more so for a 4x4 because you have to get both
axles re-geared unless you plan to not use 4wd.

If you have ABS, you'll need to take that into consideration as well.

Matt,

Yes, sorry I don't know what I was thinking. It is 3.07 and DANA 30 / 35
Front / Rear.

> Depends on your definition of "non-crazy expensive." Most of the expense
> of re-gearing is in labor,

Hmm, after the last time I posted here I talked to mechanic and he told me
that my best bet would be to track down the carrier myself because that was
the most expensive part of the whole thing. He said it would probably run
$400.00 just for the part (per axle) if he got it and he thought I could
probably find one online for a fraction of that. His labor was only going to
be about $200.00 (per axle). I ask around and talked to a lot of people
before I went to this guy , he came highly recommended. One other guy that
was also highly recommended for axle work wanted $800.00 an axle. I didn't
bother asking if that included parts.

Yes, I had all the "how-to's" downloaded and printed out. I have the rings
and pinions. I was all set to get started doing it myself when everyone here
informed me I was going to need a carrier. At that point I realized I was in
over my head... I almost had my axles all pulled apart in the driveway and
was really just asking a last minute question of some kind here. I can't
imagine how long or far I would messed with it before realizing the my ring
was not going to bolt to the carrier.... or maybe I would have managed to
get it on there ! Then end up tearing the hell out of it all 2 feet out of
the driveway.

I'm going to check the salvage yards and see what I can come up with. I've
already decided that if it requires opening up the dif then I'm having
someone with experience do it.

> Sounds like you married the right woman...

She made it clear she married me for the Jeep. :) Your right though. I'm a
pretty lucky guy.


Matt, thanks for the info !
