Recall 17V315000 — POWER TRAIN:AXLE ASSEMBLY Defect in 2017-2017 WESTERN STAR 5700

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.

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.

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.
