Differential ID

Both wheels spin the same direction when I rotate one tire.

The gear ratio is 3.50, not 3.25. Actual drive shaft revolutions divided by
tire rotations after the play was accounted for. It didn't have much play
anyway.

Numbers on the 10 bolt casing that goes into the axle housing are:
68 DIF
Five numbers in a circular pattern are 18753 (read from a dot outside the
circular pattern and between the 1 and 3 and going clockwise)
9C25

Numbers on the 5 bolt cover at the U-joint are:
9C26
C5AW
4668A
16
DIF
