    What are the axle codes again? Trying to figure out my buddies so we can order new gears, but dont want to pull the covers.

    passenger side axle tube, towards middle of tube, facing forward as it sits in the vehicle.

    Why insist on counting when the ring gear has the tooth counts stamped in?

    Just in case you mean the RPO codes, they are as follows:

    GU4 - 3.08
    GU6- 3.42
    GT4(or 5X1)- 3.73
    GT8(or GT5)- 4.10
    G80- Limited Slip

    Don't trust the axle codes ! They are way over ratted !
    Just roll the vehicle and count, works every time, all the time, independent of Locker/Limited Slips.
    Good luck

    I just needed to know if he had 3.08 gears or numerically higher so we can do 4.56s without having to change cariers.

    Ok, you have heard about extra thick ring gears ?
    Not spacers. Most popular ratio's are now avaible this way, so you can go from 3.07:1 to 4.55:1 without
    a carrier/case change.
