Recall 17V-535: 2016 Mack Pinnacle (CHU), 2016 Mack Pinnacle (CXU)
Mack Trucks, Inc. recall for steering, reported to NHTSA on Aug 31, 2017, covering about 439 vehicles.
The problem
Mack Trucks, Inc. (Mack) is recalling certain 2016 Pinnacle CHU and CXU diesel trucks equipped with certain Dana steer axles. The castellated nut and cotter pin on the steer axles may not have been properly torqued, allowing the tie rod to loosen within the steer axle.
The risk
If the tie rod loosens, it may disconnect from the steering knuckle, causing a complete loss of steering, increasing the risk of a crash.
The fix
Mack 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 October 17, 2017. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0408.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
