I'm purchasing a used Avalanche and I need to know how to tell which rear axle it has. The salesman's word alone is not good enough for me (some of these guys don't know anything), so I want to see it for myself.

So, how do I tell just by looking?

Thanks,
Scott Gunn
 
Scott:

Look at sticker in glove box for three letter codes (RPO codes). Find ones that begin with G (they are listed in alphabetical order). GT4 is 3.73, GT5 is 4.10, and G80 is locking rear axle. It's that simple!
