Caterpillar Inc. (Caterpillar) is recalling all 2016 Navistar CT660S 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.
Caterpillar will notify owners, and dealers will tighten the castellated nut and tie rod, replacing them as necessary, free of charge. The recall is expected to begin December 08, 2017. Owners may contact Caterpillar customer service at 1-800-447-4986.
