Transport Canada Recall - 2016495 - MACK

On certain vehicles, the cap nut that retains the interaxle driveshaft yoke to the rear axle input shaft may prematurely loosen. If the nut were to loosen and come off, the yoke could separate from the axle input shaft and cause the drive shaft to disconnect. A disconnected drive shaft would result in a loss of motive power, and create a road hazard, both of which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect the torque on the cap nut, and the nut will be replaced if the torque is found under specification. Note: This is an expansion of recall 2016-079.
