Hello Everyone .. long time no log on since I am still looking for a replacement to my Envoy XL. Anyway, I searched the forum and could not find an answer, Outside of a dealer/seller listing the G80 option .. is there a way to tell it is in fact there? Something I can look at or test? IS the cover different some how. Just figured to ask Any ideas would be helpful.

Other than opening up the rear end, there is no physical way to just look at it and see. That I know of.

If you jack up both rear tires and spin one side the other side should spin in the same direction, if it does that a pois rear end. If it moves in the opposite direction it's not. You can also try jacking up just one side and see if you can spin the tire, it might move a bit but it should lock.

^^ won't work on a G80, it will appear to be an open diff.

On my phone now, but search YouTube, user same as my member name here,"testing a G80“.

Only time both wheels spin the same way is with a full locker like a spool. No road going rear end will be that way. Or else you'd be wheel hopping around every corner you turn. Limited slip is what all street rear ends are. Some are tighter than others but they all give. Or else the hopping. Spools are mostly for drag racing mud racing etc
