NAVISTAR issued a recall on multiple vehicle models

On certain vehicles, the radius on the cone of the inner wheel bearing was incorrectly machined resulting in improper seating of the cone against the seal flange of the steering knuckle. Improper seating of the bearing can increase the stress level on the steer axle knuckle spindle as well as bearing movement and excessive bearing end play. This can result in premature bearing wear, eventual fatigue failure of the axle spindle and loss of steering control. Correction: Inner wheel bearings will be inspected for proper seating and bearings that do not seat properly will be changed. The axle spindle and bearing cup will also be inspected for any damage and will be changed as required.
