Mack Pinnacle (Cxu), Pinnacle (Chu): Steering — tie rod assembly

The hazard

If the tie rod loosens, it may disconnect from the steering knuckle, causing a complete loss of steering, increasing the risk of a crash.

What to do

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.
