Locked or Open Differentials?!?!?!

I've been told that. Anything simpler?

Yeah, hold the motor against the brakes and keep mashing the gas and then let her rip! If you get both wheels spinning you have a posi/locker/limited slip and if only the rr wheel spins, you have an open rear. It's the most fun way to check btw!

I was gonna post a similar question but Ill ask it here. I have an 06 2wd Tahoe PPV that has no indication G80 on the RPO sticker. I had thought about swapping in a locker/posi unit but I noticed when I step on the gas driving in sand or on the grass it will pull both back tires. Is this normal for an open diff? I have all the records on this rig and there is no indication of the rear being swapped out or anything added

Jack it up, trans in neutral, rotate one wheel, watching the other. If both rotate the same direction cool. Put trans in park. If rotating is difficult to make the other wheel rotate opposite, you have the good rear end. If it rotates easily, it is not the good one.
