NHTSA campaign 17V594000
Hazard
Ford Motor Company (Ford) is recalling certain 2015 F-650 and F-750 trucks, 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.
Consequence
If the tie rod loosens, it may disconnect from the steering knuckle, causing a loss of steering control at lower speeds and increasing the risk of a crash.
Remedy
Ford will notify owners, and dealers will inspect the torque of the castellated nut and tie rod, tightening it as necessary, free of charge. The recall is expected to begin November 20, 2017. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 17S30.
