wow, gotta go with a great write up on this one, i am printing off the write up itself to help with my installation when the time comes, and that time is coming very soon. I love when people do write ups for upgrades like these that help out the basic mechanic and the learning impaired, it looks nice in books with the basic pictures they show in black in white, these pics are real good and really help. I have to admit being a little on edge about doing it myself since this is my DD also, but I am confident about getting it done with this write up and a few hands from the club.

Do the 30 front. Spending any money on the 35 rear is a waste of time and money.

I'd rather be judge by twelve than carried by six.

Aussie Locker Backlash-

Hello,
I just installed an Aussie in my D44 rear axle. Everything went well (Including the test run before buttoning her up) but I notice on tight turns I get a (kinda loud) pop every once in a while and some extra backlash (bucking bronco). Ex: Pulling into a parking space. How much backlash is normal? I put in Mobile syn gear lube, should I also add a friction modifier??

Thanks for the help!

Someone else may be able to chime in but I'd consider looking into a friction modifier if it doesn't have some in already. The modifier should help the two dog plates slip on each other easier (it reduces friction even more so than just stock lube) and can help remove some of that banging. I didn't end up running an aussie in the rear end but I did notice the front end pops got lesser as the unit "worked" itself into a comfortable fit. It may just need some miles to find it's own in there.

My jeep has only ever killed 3 things, a cat, a deer, and my wallet. What's the problem officer?

You will not need to add any type of different fluid, when going around corners (especially tight ones) try to coast through the corner. If you're on the gas it will lock up and then pop when you get off the gas.

I pretty sure that in the directions that come with the Aussie specifically states not to use synthetic gear oil but to only use standard dino gear oil.

This is actually a good point I didn't think to mention. It's been so many years since I read the aussie instructions I can't remember off hand if it said this or not, in fact I'm not even 100% sure what oil I put in my D30 when I originally did mine.

I know alot of traction options do have VERY specific rules on the oils used. The auburn LSD for example has been known to literally break down if used in full syn diff lube. The aussie is more stout as it's a full locker as compared to a clutched LSD but the oil can cause it to misbehave.

Aussie Locker Lube

Here's an excerpt from the installation manual-
"Before starting the installation be sure that you have replacement gear oil of the type recommended by
the vehicle manufacturer, and any seals that will need to be replaced. If the vehicle is to be used in hot
weather we recommend the use of 85-140 gear oil, which will provide adequate lubrication and minimize
any sound. Also, synthetics can be used with the Aussie Locker."


I'm guessing my Mobil1 75w90 synthetic is ok. I did add a friction modifier to it last night, but its too soon to know if it helped yet...

Thanks for the feedback and please keep it coming!!!

okay could you post up a list of stuff thats handy to have like outside of tools that would be really sweet such as like wood, brake cleaner, spray bottle ext... because im only 16 and i have never opend up a diff and im planning on installing one soon and it sounds easy enough for me to do i just want to make sure i have all this stuff together when i start

and also you said you had to scrape the gasket off of the housing... did you have to buy a new one and also what other extra parts did you have to buy outside of the locker, gear oil, rvt, and brake cleaner.


Thanks for this write up its one of the best i have found on installing the aussie

You don't have to buy a new gasket for the diff cover you can use rtv as a gasket in between your diff cover and the axle housing. brake cleaner is nice for cleaning out the housing and all of the part you take off. I bought the locker, new axle seals(was installing chromos and just good to do while you are there), gear oil of your choosing, you can use a mallet to remove the tie rod which will make it much easier to remove the carrier if you have to, there aren't really any specialty tools you have to get to do this mod. simple sockets, prybar, screwdriver will be good unless you are installing new axle seals then you'll need something to press them in with. a punch is nice for marking the bearing caps, and ring gear. I'm sure someone will add to this.
