Chrysler is recalling about 257,000 model-year 2005 Dodge Ram 1500 pickup trucks.
In the affected trucks, the rear axle pinion nut may loosen due to an undersized spline on the pinion gear.
If the pinion nut loosens, the rear axle may seize, or the driveshaft may detach, resulting in a loss of vehicle control.
Chrysler will notify owners affected by the recall and dealers will install a retention feature to the pinion nut, free of charge.
For more information, owners can contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is P77.
