Finally did the re and re on my rear end. I have no idea what the gears are in the new rearend or the old one.

So now I need to know how to tell so that I know if I can engage 4 wheel or not.

10 bolt slayer!!

if the diff cover is off, count the teeth.

# ring gear teeth divided by pinion teeth gives you the ratio

ex: 41 ring gear/10 pinion = 4.10 gears
