Defect: PACCAR Incorporated (PACCAR) is recalling certain 2016 Peterbilt 220, 320, 325, 330, 337, 348, 365, 367, 382, 384, 386, 389, 389G, 567, 579 and 587 trucks and Kenworth K170, T170, T270, T370, T440, T470,T660, T680, T800, T880, and W900 trucks equipped with certain Spicer D or E series steer axles. The castellated nut on the steer axles may not be properly torqued, allowing the tie rod to loosen.
Risk: 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.
Fix: PACCAR 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 began on November 13, 2017. Owners may contact Peterbilt customer service at 1-940-591-4000 or Kenworth customer service at 1-425-828-5000. PACCAR's number for this recall is P817-C.
