Fixed. Hopefully image shack doesn't dump them again.

Buy the aussie right from the supplier, it doesn't get cheaper than that (other than used units). Any gear oil can be used, but it's normally recommended to use one that is also approved for limited slip\posi traction diffs as it'll smooth out some of the pops and bangs the locker makes.

Note: A friend of mine installed a Aussie in a D-35C (in his yJ) & used the center pin provided by Aussie. Their center pin wore the carriers hole ob-longed/egged shaped. We even had a rep out to check @ a local garage. They sent us a new locker but when we used a micrometer the Aussie pin was smaller then the original, thus wearing out the carrier's hole. Aussie could not comment, nor could the rep. I have talked to others & they used their factory center pin to combat this. We removed the brand new locker & installed a Detroit.

P.S. We thought it was popping, (enough to rip the axle end off) (driving straight) due to the Lucas synthetic. Then we replaced the synthetic w/regular dino oil but it continued. Replaced w/Lucas synthetic, again, & then found the center pin problem.

Aussie Locker Write up Comments are further down the post on the center pin problem, basically the same thing I said here.

Thanks for the write up.... I have the 3.07 30 do i have to take off the carrier? If so, what steps do I skip or point to a write up..... Thanks for helping!

Basically you can do 1 of two ways.

1)Plan on having to remove it, tear the cover off, drain the fluid, and look at the cross shaft, if it's partiallly "blocked" by a gear tooth then yank the carrier and do it this writeup way. If it's not blocked from coming out then just pop the retaining pin that holds the cross shaft in out of there, pull the shaft, then roll the gears out and replace with the locker (axle shafts of course still need to be removed).

2)Do an exploratory run, pull the cover, see if it's blocked or not then put it back on and refill with oil and plan for when u wanna do the whole job.

Sorry if the spelling is off, just sliced the hell outta my finger and am goin to get stitched up soon. Laters

Wow... wounded and still responded. I appreciate the help!

I just spent over an hour reading all 5 pages and I think it will be great. I just bought the locker today. I am going to go ahead and assume it is almost the same in a TJ from what a previous post said? If it took me over an hour to read I am assuming it will take a while to do. How long did it take you? I guess I will plan on riding in the rain. Thanks!

It took me a few hours (yes the TJ install will roughly be the same as a YJ install, maybe less tricks) but that's because I took a very calculated pace so I wouldn't leave out anything by accident. Also I didn't have a guide to follow so I was making a list of tips I read and was figuring it out as I went. It's definitely a doable job just make sure not to go on autopilot while working and forget anything. Good luck with the install

Any reason the aussie locker install or performance would be any different on my 08 JK with a Dana 30?

Do these lockers wear out like some limited slip diff's after 20-30k miles?

In 2 wheel drive, is there absolutley no difference in behavior? (I let my kids drive the jeep on the highways, in the rain, in 2wd, I don't want to find out that it makes it more dangerous.

thanks

Personally I've not looked under an 08 and couldn't even tell you if they still run D30's. If it IS a d30 axle then the install would be almost completely identical unless there was something different OUTSIDE the axle that would need to be moved in order to pop the cover. If it's not a full time AWD based 4x4 but rather a "shift it into 4x4 when I want and turn it off when I want" it should be invisible like on the YJ's and TJ's because no torque would be present in the front axle to cause the locker to want to lock. They do not wear out as they have hard faced teeth that cause the lockup, not clutches like LSD's.

I'm pretty sure the two front axle options for the 4wd non-rubicon jk are hp dana 30 and hp dana 44. Not sure if they offer a lsd in the front of those though.

Thanks for the info. While looking for gears, I was poking around and found this: "THIS GEAR ONLY FITS NON-RUBICON 2007 WRANGLER FRONT AXLES. Jeep changed the long-produced Dana 30 to use different gears, carriers, bearings, yokes and all. None of the parts for a 2006 and older Dana 30 will work with 2007 and newer Jeep Wrangler axles. "

at this site: http://www.4wheelerssupply.com/catalog/product_info.php/products_id/71697

So it seems your info is good, but I have to be careful to get one for a new model Dana 30.
