Locker Options for WK

So I'm going to put a locker in the rear in the upcoming months but I have some questions. First off, I have an 05 limited 4.7 L with quadra trac 2
1. The rear axle is listed as 213 mm which is 8.38" however I thought the WK had the Chrysler 8.25" so what exactly fits in the rear axle?
2. If it is 8.25" then it is either 27 spline or 29 spline. Is the only way to know for sure to pull an axle shaft and count?
3. If I do have to pull a shaft, are they floating shafts or are they c-clips?

I'd like to do an Aussie or lunchbox type locker such as a trac lock or something along those lines. Anyone running lockers and have advice?

Any help is appreciated

When I was researching custom diff covers my noggin also absorbed the following bits of info which I will post for you, although I don't pretend to understand it:

The casing (pumpkin), and ONLY the casing, is a Chrysler 8.25. Everything else inside conforms to the 213mm standard. ISTR also that it was an odd spline count and none of the usual suspects would fit it.

Someone who knows what they're talking about will post soon and provide full and correct info. In the meantime I would be VERY skeptical of anyone who assures you it's an 8.25 inside.

Hmmm that's very interesting. Thanks for the info! I'll have to keep all that in mind. Hopefully someone running a locker can shed some light on it

When Nitro did their WK build, the used an ARB for the 8.25. I don't see a spline count.

With the exception of the SRT8s, all the WK/XKs have a C8.25 29 spline rear axle.

Thanks for all the input. Unfortunately, an ARB air locker is out of the question for me due to money. I'm hoping that I can figure this stuff out and get an Aussie or something else similar to that

there's a few guys on here that have already done the Aussie locker you just have to search http://www.jeepforum.com/forum/f67/a...-rear-1246750/
I'm pretty sure you can find at least one guy with a powertrax as well
Good luck

Only very early 8.25" axles were 27spline. I'm not talking early WK axles either, I'm talking early in production of the 8.25 overall.

FWIW...

Yeah I saw that earlier but wasn't sure since I didn't know the spline count. I just want to verify before purchasing anything but all of this definitely helps. Thanks guys!

They are c-clips... floating is usually only on 3/4 ton+

If a True Trac would work, one would then assume a lunchbox type setup such as the Powertrax No-Slip would as well. That would save you from having to swap carriers and thus the added labor of re-shimming the diff and getting installing carrier bearings.

Im very interested in the rear Aussie locker that user Lifted_Up installed here http://www.jeepforum.com/forum/f67/a.../#post11999279
It seems very nice, an im sure I could live with the daily driving quirks. And the price isn't bad at all. I can afford $299, but $1,000+ for an air locker..... not gonna happen for me.


But I have one question, why the rear?
I was talking to my brother and he says that a lot of JK guys will put lockers on the front first. For two reasons..... 1. Less problems with daily driving even with AWD because the front's arent being used very often 2. Rock crawling and "step-up" situations, wouldn't it make more sense to have your fronts locked since those are going to be up on the the rocks or higher ground first, essentially pulling you up?

Do we not have a locker option for our fronts?




EDIT:
There is also the spartan locker that fits our rear.
