Defect, in the NHTSA record
Mack Trucks, Inc. (Mack) is recalling certain model year 2012, 2014-2015 and 2017 Granite (GU), 2012-2017 Pinnacle (CHU, CXU), and 2013-2015 and 2017 Titan (TD) trucks manufactured January 7, 2011, to September 29, 2016. The affected vehicles were built with front wheel hubs that cannot support the gross axle weight rating of the front axle.
Consequence, in the NHTSA record
Overloaded front wheel hubs can result in premature failure of the hubs, bearings, and the related components, which can cause the front hub assembly to separate from the front axle. Because of this, the driver may lose control of the vehicle or parts may be dropped on the road, increasing the risk of a crash.
Remedy, in the NHTSA record
Mack will notify owners, and dealers will replace the hub assemblies, free of charge. The recall began on February 16, 2017. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0406.

Remedy, in the NHTSA record

Consequence, in the NHTSA record
This can result in seam weld fracture when torque is applied. Once the tube seam weld is fractured, the driveline may become inoperable which may result in a disabled vehicle or debris from the driveline may fall on the roadway, both of which can increase the risk of a crash.
Remedy, in the NHTSA record
Dealers will replace the drivelines free of charge. The safety recall began on july 25, 2011. Owners may contact mack trucks at 1-800-528-6586.

Due to an incomplete "knitting" of the iron at the time of casting, inadequate structural integrity of the slack adjuster housing can occur, which could cause the housing to break at the handle under normal operating loads.
Consequence, in the NHTSA record
Slack adjusters with this flow notch could crack under normal braking conditions causing loss of braking which could result in a vehicle crash.
Remedy, in the NHTSA record
Mack trucks will notify owners and dealers will replace the subject slack adjusters free of charge. The safety recall began on august 24, 2011. Owners may contact mack trucks at 1-800-528-6586.
