United States 17V315000
Daimler Trucks North America, LLC
The problem
Daimler Trucks North America LLC (DTNA) is recalling certain 2017 Freightliner Cascadia and Western Star 5700 trucks built with NFD tandem rear axles. During the hardening process, the axle assembly output shaft may have been made brittle, possibly resulting in the output shaft fracturing while the vehicle is in use.
Risk
If output shaft fractures while descending a grade, the compression braking will be ineffective. Additionally, large debris may land in the road. Both scenarios increase the risk of a crash.
What owners should do
DTNA will notify the owners, and Detroit Axle dealers will replace the output shaft, free of charge. The recall began on July 7, 2017. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL-738.
