Summary

Some 2020-2021 F-53 Motorhome Chassis/F-59 Commercial Stripped Chassis vehicles may exhibit an anti-lock brake system (ABS) light on with diagnostic trouble code (DTC) C0037 and/or C0038. This may be due to a bent or damaged rear axle tone ring. Inspect the tone ring teeth on the affected rear wheel and replace the tone ring if damage is present. It is recommended to inspect the service tone ring before installation to make sure no damage has occurred in shipment. The tone ring is susceptible to damage during the ring to rotor installation as well as installing the hub and rotor assembly onto the axle housing. Use a suitable jack to aid in the installation of the assembly to prevent any contact with the tone ring during reassembly.
