Aussie locker on rear D35

i was wondering about maybe getting a Aussie Locker for my open D35, I have 3.73 gears and running 33" tires.Now i know that my gearing is terrible for that size tire, but I learned to drive my jeep with those size tires on it and the power loss doesn't bother me. Also id like to say, i would someday like to go to maybe 4.56's. Being a student money is on short supply and this seems like a very affordable way to increase my jeeps off road ability.


Specs:
4.0L
3.73 gears
d35 rear with 33's

Is an aussie locker safe to use on a DD?
Is it worth the 200ish dollars on my open diff? both my front and back are open
Anyone have experiance with the Aussie locker?
will the d35 with that size tire handle the aussie locker?

lock your front dana 30. locking the 35 will make it blow up alot faster. Id look into a different rear axle before spending money on gears and lockers.

Your rear Dana 35c isn't even close to being strong enough for a locker and stock size tires, let alone a locker and 33" tires. Don't do it, lock your front axle first & save up to either beef up or replace your rear Dana 35c with something strong enough for a locker. An Aussie, Lockrite, or No-Slip locker would work well in your front Dana 30.

Um, question......... Are you guys saying that the D30 front is strong enough for a locker, but the D35 isn't? If I am gonna be using my ride for DD duty and occasional off roading, nothing hardcore, will the D35 hold up if I put a locker in? This weekend, we got 10" of snow and I pulled several vehicles out of ditches, wishing I had better gearing and/or lockers even though my Jeep did great.

Yep, the front Dana 30 is strong enough for a locker up to about the 35" tire size because it never gets more than about 50% of the stress the rear axle sees regularly.

I don't care if you don't do "hardcore" stuff, a stock Dana 35c is not strong enough for a locker. Eventually it would break, no matter how gentle you were on it.

The bottom pic shows how I kept a wheeler's busted axle shaft from sliding out of the axle housing taking the wheel & tire with it like has happened in the top photo. That's a Hi-Lift support held to the frame with straps.

Thanks for the info, i was heading down the road to just gears and lockers and 33" tires. Gonna have to definitely rethink a few things now. Truthfully, I just got my jeep 2 weeks ago, and I haven't crawled under to see what I have under the back. sure be nice if it was a D44!

Okay, if i was to lock the front! it says on the site that they don't recommend locking the front axle of a highway vehicle?

"We "Do Not" recommend the installation of a locker in the front of a vehicle that will be driven on icy highways in 4WD without manual hubs."


will throwing a Aussie locker in the front end make a large difference still with the rear being open? would it be worth it to just lock the front end?

While that warning is appropriate for many 4x4 vehicles, it is not appropriate for a TJ so long as you remain in 2wd.

And per their poorly worded warning, you wouldn't even be in 4wd if you had selected 4wd but unlocked your manual hubs. Selecting 4wd but unlocking manual hubs, if present, would be the same as if you were in 2wd.

When you're in 2wd, you can't even tell the locker is there... the steering is totally unaffected. At the most, you get a mild soft clicking during turns when you're in 2wd though not even that if you spend a little more to get the No-Slip locker from Powertrax.

Funny I've been beating the crap out of my 90 YJ with the original d35 & lock right locker in it with no problems for 2 years now. I wouldn't recommend going over 33s with the d35. I also wouldn't put a locker in the front. I've had a few friends do that. The Jeep handles terribly on the trails while turning. In slimmey, muddy situations they just pushed forward instead of turning. A selectable locker would be best.

There's no need to be confused. Adding a locker to a Dana 35 is eventually a sure ticket to a busted axle shaft. I thought I could be "gentle" to my previous Dana 35c with a locker & six weeks after installing it and one offroad trip where I babied it, it blew while I was doing a very slow speed u-turn at a light controlled intersection in downtown San Diego. It made enough noise when it blew that people a block away turned to see what had happened.

There will always be a few who brag that their locked Dana 35c stands up to them "beating the crap" out of them but I've got a few hundred pics I've collected over the years of various busted locked Dana 35c axles where not all were beating the crap out of them.

Where as a front automatic locker goes, I've had one (a No-Slip) in the front of my TJ for years. I also have an automatic locker (Detroit Locker) in my rear D44 that replaced my D35c. On the street in 2wd, you could not drive my TJ and detect the presence of my front automatic locker. On the trail in 4Hi or 4Lo, it works awesome though on perhaps a tight twisty trail, steering can be a little stiffer with a front auto locker. But if you check out my website and some of the trails I like doing, I'd have to say it works damn well. Automatic lunchbox lockers (Aussie, Lockright, No-Slip) in the front Dana 30 axle are probably THE most common locker that gets installed into a TJ.

Those who are naysayers to a front automatic locker don't actually have one installed in their TJ, they only tell about their friends.

The only proper way to lock a D35 is with Superior's Super35 kit. This kit defaults with a Detroit Softlocker.

A lunchbox locker in a D35, is not recommended; however, they do well in the front D30 .
