NHTSA campaign 17V575000
Hazard
Navistar, Inc. (Navistar) is recalling certain 2016 International DuraStar, LoneStar, ProStar, TerraStar, TranStar, WorkStar, 9900i, and IC Bus HC vehicles 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.
Consequence
If the tie rod loosens, it may disconnect from the steering knuckle, causing a complete loss of steering, increasing the risk of a crash.
Remedy
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 17507.
