Ok this might be a dumb question. Does a 02 Sierra come factory with a locker? I know the newer ones do. The reason im asking is, being icy and all its easy to get carried away. Now, when im leaving for work in 2wd i start to pull away, the rearend hops....bad....and it even sounds like something is loose underneath my truck. I know it might just be wheel hop, but Ive already had enough problems with my truck and i think im just paranoid that something else is going wrong. Just checking to see if there's any other common, serious problems these trucks have like the tcase and injectors ect. thanks

Its wheel hop a lot of our trucks do it if you have the g80 it makes a nasty noise when it engages if you’re giving it power too.

Check the RPO codes in your glovebox for a GT4 or GT5.

Your right, I must have had the old brain in neutral when I let out the clutch.
