Axle Ratio? More info

[Ogier]

Greetings all,

Ok, I have jacked up the rearend of the truck and did the whole tire turn/ count the pinion turns thing and here is what I get:

Tire: 4 full turns
Pinion: 8.25 turns estimated.

I am coming up with a ratio of about 4.84.

The closest ratio that I can see referenced is a 4.88 for the Eaton.

Given the estimation of the pinion turns, I see this as plausible.

Did I do the math right?

Thanks
