GU4 - Axle Ratio 3.08, Rear
GU5 - Axle Ratio 3.23, Rear

And for some reason I thought the code for 2.73's was GU3, but I could be wrong about that one.

jack it up in back so that both rears are off the ground. Put it in neutral. Put a mark on the driveshaft and rotate the tires one full spin (exactly) while counting how many rotations your driveshaft makes. If the shaft spins 3.42 times to the tires once, there ya go! 3.42s

But if you don't have the door sticker, or you think the rear was swaped, that meathod would work.

if he doesnt have a posi you will have to reverse the process, counting the driveshaft and watching when the tire turns one time
