MACK issued a recall on the CXU, CHU, and TITAN models

On certain vehicles, the front hubs do not support the gross axle weight rating of the front axle. Specifically, 5,987 Kg (13,200 lbs.) rated front hubs were used on trucks requiring a 6,622 Kg (14,600 lbs.) rated front axle. If the axle load exceeds the maximum weight capacity of the hub, there is an increased risk of hub and bearing failure, which could cause a complete separation of the wheel(s) and a loss of vehicle control, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace the front hub assemblies with hub assemblies rated for 6,622 Kg (14,600 lbs). Note: If damage occurs due to overloading, the ABS Malfunction light may illuminate as the distance between the ABS tone ring and the sensor increases (i.e. sensor loses contact with the tone ring).
