Summary

Mack Trucks, Inc.

The cap nut that retains the interaxle driveshaft yoke to the rear axle input shaft may loosen.

Consequence

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.

These repairs will be performed free of charge. An interim notice was sent to owners on April 25, 2016. The recall began on June 7, 2016. Owners may contact Mack customer service at 1-610-709-2131.
