how to tell gear ratio?

[jeffseal]

I just got a new 8.8 it is supose to be a 4.10 how can i tell the gear ratio. the metal tag on the diff cover is gone.
also has no axle shafts in it so i cant turn them to count rev. of drive shafts.

figured it out.

here is how i did it:

look threw the axle housing and you can see the slide pins then i counted the # of turs of the driveshaft it took to turn the slide pins 360 degrees. it was a little over 4 so i have my 4.10

Hey you can look threw the axle housing and you can see the slide pins, then count the # of turns of the driveshaft it takes to turn the slide pins 360 degrees. You should be able to determine it that way

You could just turn the axle (or where the axle bolts on) until the rotors make a complete turn (and count how many rotations the axle made). Least you won't have to tear into it that way.
