The defect

Daimler Trucks North America, Inc. (DTNA) is recalling certain model year 2015-2016 Freightliner 108SD, 114SD, Business Class M2, and Western Star 4900 vehicles manufactured September 26, 2014, to November 6, 2015, and equipped with certain drive axles manufactured by Marmon-Herrington. The affected axles have hex nuts on the flange yoke that may not have been properly tightened.

The risk

If the hex nuts are not tightened to specification, the driveshaft may disconnect from the drive axle, resulting in a loss of propulsion and increasing the risk of a crash.

The fix — what to do

DTNA will notify owners, and dealers will inspect the hex nuts, tightening them as necessary, free of charge. The recall began on February 5, 2016. Owners may contact DTNA customer service at 1-800-745-8000, or Marmon-Herrington customer service at 1-800-547-0712. DTNA's number for this recall is FL-699.
