Locked or Open Differentials?!?!?!

[Onebad1983]

You need this info for brakes. Since when?

No clue dude.

I've been told that. Anything simpler?

The RPO codes.

The RPO codes.

What code would it be for limited slip?

What code would it be for limited slip?

G80. Do you have GT4?

G80 is for locked I thought?

The Eaton G80 is unique in the fact that it is a limited slip differential that locks under certain conditions.


My understanding is if you don't have G80, then you're open. I don't know of any other options. @swathdiver? Jack up the rear and watch the wheels spin in opposite directions.

This thread is both informative and entertaining ...

I looked up RPO G86 and it comes up as

G86 Axle Rear, Limited Slip.

On a few of the sites i saw discussing this they said that G86 was used in quadrasteer equipped pickups and they never knew it was available in a tahoe or yukon. Maybe it was possible to order one with that option or someone broke the glovebox door and replaced it with one from a truck. I would just pull the diff cover and remove all doubt as to what you have.
