Defect

Chrysler Group LLC (Chrysler) is recalling certain model year 2005 Dodge Ram 1500 trucks manufactured January 28, 2004, to August 3, 2005. In the affected vehicles, the rear axle pinion nut may loosen due to an undersized spline on the pinion gear.

Safety Risk

If the pinion nut loosens, the rear axle may seize, and/or the driveshaft may detach resulting in a loss of vehicle control, increasing the risk of a crash.

Remedy

Chrysler will notify owners, and dealers will install a retention feature to the pinion nut, free of charge. The recall began on June 26, 2015, 2015. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is P77.
