The tag under one of the cover bolts is the best way, but there is also usually a sticker in the glove box on trucks that lists all the optional equipment. The dealer may be able to help with the vehicle ID number. As a last resort you can remove the rear cover, then the ratio will be stamped on the outer edge of the ring gear.
