What do you want to know?

Have you seen the 14bolt bible (http://www.pirate4x4.com/tech/billavista/14b_bible/index.html)?

I wanna find out the gear ratio. "The Bible" didn't help. I have numbers off the axle tube:
RNU G25 11

You won't get the axle Ratio off the BOM
You need t0 pull the cover, ratio is stamped on the Ring Gear

You could always spin the tire once and count how many times the yoke spins. :)

Yea, but there are to many variables that effect that method, for it to be an accurate way to determine ratio.

Count the teeth on the pinion and the teeth on the ring. Pinion equals 9 ring equals 41. 41/9=4.56

That's how i found the ratio in the junkyard. The tag was gone.

I just stopped one side from spinning, spun the yoke until the drum had made one full turn. But since one drum can't spin, the other will spin 1/2x as much. So 8.2 turns on the yoke and you've got a 4.10 gear set. Once i got it home i cracked it open and made sure, but it worked.

Crazy_Jeepman, does having a Gov-Lock in it affect this method? All i'm sayin is it's the easiest method, maybe not the most accurate, but close enough.
