Mack cap nut that retains the interaxle driveshaft yoke to the rear axle input shaft may loosen.
The short version
Mack Trucks, Inc. reported a problem with the driveline driveshaft. Here is what owners need to know.
The cap nut that retains the interaxle driveshaft yoke to the rear axle input shaft may loosen.
If he cap nut loosens and falls off, the yoke can separate from the axle input shaft and allow the drive shaft to disconnect, increasing the risk of a crash.
Mack will notify owners, and dealers will replace the cap nut, free of charge.
