Navistar, Inc. is recalling certain model year 2014 International Prostar trucks manufactured September 2013 through December 2013, and equipped with feature code 14GXP 6X2 rear axles with 'R' hubs and Dual Track rear axles. In the affected vehicles, axle shafts of an incorrect length may have been installed which can cause the splines on the axles shafts to be only partially engaged into the side gears of the rear axle differential.

The partial engagement could cause the axle shaft splines or side gears to fail which may result in loss of power to the drive wheels causing the vehicle to stall on the roadway, increasing the risk of a crash.

Navistar will notify owners, and dealers will replace the incorrect wheel hubs and axle shafts with the correct ones and replace any damaged side gears, free of charge. The recall began on March 18, 2014. Owners may contact Navistar at 1-800-448-7825. Navistar's number associated with this recall is 14506.

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 'TTY 1-800-424-9153', or go to www.safercar.gov.
