So I just bought a rig with yj axles under it and I'm not sure what gears it has. I've worn out Google trying to find axle codes but all I seem to be coming up with is lists of what axles came under what Jeeps, not the gear ratios. Even tho its not a hard job, I really don't want to pull a cover and count if I don't have to. Any body have any clue what codes mean what? I think I found that 46-15 is a 3.07 and 46-13 is a 3.54. But what about 3.73 and 4.10? ( I tried searching 46-11 46-09 etc no luck):o
