23 75 2K18. I get this as 7.5 Dia Ring Gear, 2002 Nov 18.

What's the 23?

I must have searched/tried 50-60 posts and web sites.

 

You're missing some numbers there.
Look on the driver's side door/door post for the axle code and post that.

edit
see if this helps you

Of the 50-60 posts and web sites.... was google one of them? Took me about 2 seconds to find this.
Ford Ranger Axles - The Ranger Station
That should help ya, along with what Ken posted.

 

Oops. Well the door sticker says code 86 and I got that figured out. Its the numbers on the tag bolted to the Diff that I was interested in as a double check.

This is a 2003 Ranger. The entire tag reads:

V 868 K
23 75 2K18 What's the 23?

 

Hi again -I read all that stuff plus lots more -didn't quite fit my tag format.

 

I dont think it reads 23. Its probably 73 and you are missing the 3 infront of it

 

^^ Agreed. The bolt that holds the tag on often covers up part of the code.

 

BINGO!!!!!!!!!!!!!!

It read 73 presumably for 3.73, Thanx - sorry I didn't recheck B4 asking.

 

yea, if it says 73. i'd gues you've got 3.73s. someone beat me to the whole "might not be a 2 might be a 7" post.
i'm also guessing it's an open dif since there is no L or L/S that you posted up in the code.

 

Can't be open - doesn't leak a drop

 

i can't tell if that's sarcasm or not. But he meant an Open Differential, as in no factory Limited Slip

 

Gulp! Sorry about that. It was meant to be funny. Not a very good attempt.

 

I laughed :P

 

i did too lol
