Daimler Trucks North America LLC (DTNA) is recalling certain 2016 Western Star 4900 and Freightliner Cascadia vehicles, equipped with certain Spicer D-Series and E-Series steer axles. The castellated nut on the steer axles may not be properly torqued, allowing the tie rod to loosen.
DTNA will notify owners, and dealers will inspect the torque of the castellated nut and tie rod, tightening it as necessary. If the tie rod stud and knuckle on units cannot be sufficiently torqued, the dealer will replace the knuckle and tie rod end assembly, free of charge. The recall is expected to begin December 4, 2017. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL-751.
