A Pre-Call Worksheet is provided at the end of this technical bulletin to assist in recording information.

Table A: Axle Specification Numbers included within this Program

Table B: Kit Contents

Identification Procedure

1. Park the vehicle on a level surface. Block the wheels to prevent the vehicle from moving. Set the parking brake.
2. On the front of the axle, find and record the forging date code and heat code stamped on the axle, and the axle serial number located on the identification tag on the center of the axle. It may be necessary to clean paint and debris from the area in order to see the numbers. Figure 1, Figure 2 and Figure 3.
3. On the rear of the axle, find and record the machining code embossed on the left side of the axle. Figure 4. The last five digits of the code is the machining date code. Figure 5.

4. Check for the following criteria to determine if the axle is affected.

• Forging Date Code = 14128
• Heat Code = CA
• Machining Date Code = 14214
• Axle serial number is on the list of affected axles. Refer to the table in the back of this publication.

• If the axle meets ALL of this criteria: The axle will need to be replaced according to the Replacement Procedures in this technical bulletin. Before you begin service, first contact the Meritor OnTrac™ Customer Call Center at 866-668-7221 or email the center at ontrac@meritor.com. Use the pre-call worksheet at the back of this technical bulletin to collect required information. OnTrac will create a case number and send you the kit required for service.

• If the axle does NOT meet ALL of this criteria: Follow the OEM’s program guidance to close out the program warranty claim. Note the heat code and axle serial number in the OEM claim comments. Return the vehicle to the owner.
