What is an Auburn carrier?

[Alex FX4]

Auburn is a brand, not a type. I feel like an idiot

Auburn is a brand, yes. All their differentials are all full carrier replacements as are many other brands. Carrier is the guts of an axle....ring gear attaches to it and the shafts slide into it. Within it, is the differential...whether it be limited slip or locker. Auburn Ected is a limited slip/locker that they offer. Installation of a new carrier requires a gear setup charge(backlash check, gear mesh pattern) and usually new bearings.

hope that helps.

Generally speaking though when someone says "Auburn" without further detail
they are speaking of the Auburn Cone-type limited slip.

The cone type limited slip works well, but each has the seeds of it's
own destruction in it's design.

An auburn is technically a limited slip, but in normal straight travl it "wedges"
itself into an effective lockup, and it must "unlock" to corner.
This usually isn't a problem.

where the problem is is while cornering and the unit is unlocked at some
point the driver applied power to come off the corner... at that point the
unit must re-lock and therein lies the problem...

when the unit is new and power is applied while the unit is differentiating
it will take 1 one to one and a half full turns of the inside tire to relock.
This is not a problem.

what is the problem is as the unit wears this lockup delay grows longer and longer.
The delay isn't the problem what is it that power-on the wheel accelerates through
more rotations it builds inertia

And now the real problem a worn unit locks MORE positively than an older fresh unit

So with the increased rotating inertia of a tire/wheel/axle/etc that is spinning faster
and a diff that locks harder at some point the growing inertia and the shorter more
solid lockup time... eventually these two factors reach a point where it exceeds the strength of something inside the carrier... typically either the spider gears disintegrate
or the teeth are shed off the axle pinions, some what more rarely the sintered iron cones seperate from the steel axle pinion OR the spider gear cross shaft literally tears through the body of the carrier.

In an event it gets progressively more "fun" to feel that solid lockup after a short wheelspin until it goes BOOM! (the classic "expensive sounding noise")
and you get to test the towing coverage of your AAA membership.

and if you ask around on the Corral (the big mustang forum)
I really doubt that you'll find anyone wh has ever sucessfully persued
a warrantee claim against auburn.
