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.
