I have these numbers on the crown wheel in my Blazer rear axle
2 gm 26015037 13 40 12 91
I've been told the following refers:
2 gm 26015037 = part number
13 = number of teeth on the pinion
40 = number of teeth on the crown wheel
12 = month of manufacture
91 = year of manufacture.
How right is that info??
Thanks
