Can anybody identify the gear ratio by the tag on the axle? It came from a 89 F-250 4X4 diesel and I believe it's the 10-1/4". The tag on the axle is as follows:

V131C
L10 10 2 9 J06

I'm not able to pull the rear cover off to count the teeth at this time. Thanks

 

Look closer at the tag there will be a 4 as the first digit in bottom row. 4L10 means 4.10 gears with limited slip. 10 2 means 10.25" ring gear.

 

ahhh, that makes sense. The tag is broken and the 4 is missing. Thanks, Keith
