the center of the axle beam, this ID tag is stamped with the axle model number, serial number, and date of manufacture.

The model number is composed of letters and digits (e.g., TN-4670-Q-2020). This number is used to identify the
axle assembly when ordering replacement parts.
2.
The serial number is composed of letters and digits (e.g., KNA-38050685). This number can be used to identify a
particular trailer axle, and the material and components used to build the axle.

the year, or October 3rd. The last two digits (93) indicate the year, or 1993.
