Is this a 4.10?

Can someone tell me if this is a 4.10
It came off a 2000 xj with a 4 cylinder 5 speed
The front had a 4.10 tag but the rear didn't and that concerns me
Although front and rear have to match with a 4x4 I just want to be sure.
Thanks guys!

Tobe sure, count the number of teeth on the ring gear and divide by the number of teeth on the pinion.

Is this limited slip?
I think it's definitely different than my 97 8.25 but I can't tell

No, open diff.

That is definitely an open diff, and if it's different then your 97's diff, it's either a different model axle, or maybe your 97 had some form of LSD
