REAR AXLE IDENTIFICATION
The rear axle identification code consists of a two letter prefix indicating
the gear ratio, four digits indicating the assembly date as month/day, and
a single letter suffix indicating the manufacturing location. The identification
code should be stamped on the bottom or front left or right axle
tube either adjacent to the carrier housing or about 8" - 10"
inboard from the backing plates. The warranty card protect-o-plate may show
a 3-letter prefix such as CRV for RV.
