Kenworth T680 Recall 17V593: Loose Steering Tie Rod Can Cause Loss of Steering

NHTSA campaign 17V593, reported September 22, 2017, 17,737 vehicles potentially affected.

What this recall means for you

A castellated nut on the steer axle may not be properly torqued, allowing the tie rod to loosen on certain 2016 Kenworth trucks equipped with specific Spicer steer axles.

If the tie rod loosens, it may disconnect from the steering knuckle, causing a complete loss of steering and increasing the risk of a crash. Owners should take this recall seriously and have their vehicle checked promptly.

The repair is free at an authorized dealer. Dealers will inspect the torque of the castellated nut and tie rod and tighten it as necessary; if the tie rod stud and knuckle cannot be sufficiently torqued, the dealer will replace the knuckle and tie rod end assembly at no charge. Owners can contact Kenworth customer service at 1-425-828-5000 (PACCAR recall P817-C), and should check their VIN for open recalls.
