An issue affecting the powertrain has prompted a recall from Mack Trucks.

The manufacturer is recalling certain model year 2012-2015 Granite (GU), Pinnacle (CHU, CXU), TerraPro (LEU, MRU), and Titan (TD) and model year 2015 LR trucks. The cap nut that retains the interaxle driveshaft yoke to the rear axle input shaft may loosen.

If the cap nut loosens and falls off, the yoke can separate from the axle input shaft and allow the drive shaft to disconnect. This condition would increase the risk of a crash.

The company is including about 21,000 trucks in its recall.

Mack will notify owners, and dealers will replace the cap nut. The input shaft threads will be inspected for damage. Any damaged input shaft will be replaced. These repairs will be performed free of charge. The recall is expected to begin on April 15, 2016.

Owners with questions about this recall can contact Mack customer service at (610) 709-2131.
