MACK issued a recall on the CH and CX models

On certain vehicles, a manufacturing defect in the unitized hub assemblies could result in premature spalling of the front wheel bearings, which in turn could lead to eventual breakdown of the bearing, possible front wheel separation and loss of vehicle control amidst the presence of warning signals such as activation of ABS warning light, steering wheel vibration, brake drag, noise, and vehicle pull. Correction: Dealer will replace both front hub assemblies.
