Axle info

[Nissanclay]

I'm trying to figure out what axle I have and info on it. I figure then its easier to get parts and I'm trying to learn as much about them as i can.

Here is a pic of the carrier and the number that are printed on the ring gear.

What do they mean or are they just random numbers?

to get info on the axle, you need the BOM number from the housing. you can look it up online and find out exactly which version it is.
