Navistar, Inc. (Navistar) is recalling certain 2016 IC Bus CE school buses 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.
If the tie rod loosens, it may disconnect from the steering knuckle, causing a complete loss of steering, increasing the risk of a crash.
Navistar 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 began on November 8, 2017. Owners may contact Navistar customer service at 1-331-332-1590. Navistar's number for this recall is 17508.
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.
