Daimler Trucks North America has recalled Freightliner and Western Star trucks to inspect for a potentially loose tie-rod arm bolt.
The loose bolt could lead to separation of the tie-rod arm, disconnecting the front wheels from the vehicle and causing a crash.
Daimler Trucks will inspect 501 trucks and 73 Thomas Built school buses for which it cannot find paperwork that proper tightening of the components was completed. The company received one customer complaint in January 2018 that led to an investigation.
Affected vehicle models include 2017-2019 Freightliner 114SD, 122SD, 108SD; Cascadia and Business class M2 trucks; Freightliner XBS, XCL, XCM, MT45, MT55, S2G, S2RV, XCR and XCS custom chassis; and Western Star 4700, 4900 and 5700 trucks. The buses are the 2018-2019 Saf-T-Liner C2, EFX and HDX. All were equipped with axles from Detroit Axle.
Daimler Trucks service centers will inspect the axles for free to be sure the steering arm and tie-rod arm torque are correct. They will be repaired with new fasteners if necessary.
Affected customers were notified by mail of the recall earlier in February.
