Put an indicator mark on the ring gear and spin the pinion side by hand.

Less than 4 full revolutions of the pinion side will be 3.73's and slightly over 4 will be 4.10's, a good way to confirm you got what you paid for.

(3.73 revolutions for those gears and 4.1 for that set of gears if not clear)

I don't know the tooth count for these gears, but beings two signs of 3.73 is leaning towards that, do the above to see what you ended up with.

I've got a 3.73 ring and pinion in the garage that I could go compare numbers to, but the above suggestion might be the best way to tell. I am pretty sure mine was stamped with the ratio on it, but that doesn't necessarily mean yours is.

I don't know why I didn't think of doing this trick the other day, when I had them apart. I will try it out, but I am pretty certain I have 3.73s.

I called the junk yard that I bought these axles from. Spoke to the same salesman, he is looking for a set of 4.10s for me. Said he will figure it out and get me what I need.

Saw a 4 cyl KJ being sold on Craigslist for $700 for parts. That would have your 4.10’s. It’s in CT, which might be near you depending on where you are in NY.

I appreciate it. Too bad it has a mechanical lien on it.

Well I am on my 2nd set of axles from a junk yard that were supposed to be 4.10. Both sets i got ended up being 3.73, which are no use up me.

It’s a little disappointing, first I’m getting down to crunch time on a trip. And second, this last set looks great!

In 4.10? You're in Southeastern Ohio, correct? I do get out that way somewhat often. Lets talk.
