When you say "differential carriers" do you mean the side gears? Any pics?

How did you break the main pinion bearing?

Wait, I think I know where you are...

Yes, you must assemble all, and then puth the 3rd member in, then insert axles.

Have you searched? There is a sweet rebuild by PinHead in the Tech Section:

As well as on the Aussie Locker site:

thanks pablo, the bearing came apart, probably because i just put a sb chevy in, lol. maybe cause its 35 years old also...i was hoping i could get around taking the axles off, but guess not. oh well, back to work, maybe when i get this fixed i can make it a week without somethin braking, at least my dixie air horn still works, lol...thanks again

Do you mean the threaded portions of the carrier?
These are usually a matched set so try not to mix them up side to side.
If they are mixed up you may have grief trying to thread the adjusting nuts back in.
I usually mark one side with a punch before taking the carrier apart.
