Problems with my Aussie-Locker-heavy noise

[josecito312]

Hi, I installed an Aussie-locker in the back one year and nearly 20.000 miles ago in my heavy (3,5 tons) BJ 75. We are travelling with the rig through Southamerica.
Sometimes after a few turns and u-turns you can hear and feel! a very loud "bang" in the backaxle. 2 Months ago I had to make a U-turn with 4-L in Bolivia and all the bolts of the right side in the Fullfloater-backaxle where broken. Probably some of the flange nuts aren`t fixed correctly?
So I had tu put out the cardan to drive to the next city with a workshop. I checked the dif in a workshop as well as the tolerances from the gap from the pinion shaft and the spacers. Everythings seems ok. But the heavy noise (bang o clang..) comes more often and I `m not shure if this heavy noise is normal or not. Right now we are in Buenos Aires and we want heading south to Patagonia. We don`t wont to get stuck in the middle of nowhere...

What do you think, should I check the dif again? I think the noise comes from the gears when they are "jumping" in their right posision.

i have an aussie in that back of my 4runner and it makes a bang seems to unlock hard in a tight turn but it is only once in a while seem to do that same to my friends too may want to pull the drain plug and check that you haven't sheared any pins or have to much metal flakes

btw i just spent about an hour looking at your pick looks like an amazing trip best of luck to you on your expo -nat

hi, thanks for your answer. I have another question:

When i lift only one wheel with the jack and then turning the wheel it makes more or less loud - tuck,tuck,tuck,tuck.

That´s the locker. You have the same noise like me?

cheers Jose

Hi All:

Sorry to hear about your problems Jose.

Check-out this thread - it is sort of related to your issue:

One of the guys posting in here ("Crushers") has some experience with an automatic locking differential in a full-floater rear axle.

Good luck!
