CHRYSLER issued a recall on the RAM model

On certain vehicles, the rear axle pinion nut could loosen and allow the rear driveshaft to detach from the axle, or fully detach from the vehicle. Pinion nut separation could also cause the rear axle differential to fail suddenly, causing rear wheel lockup. These issues could result in loss of propulsion, danger to other road users, loss of vehicle control and possible crash causing property damage and/or personal injury. Correction: Dealers will install a pinion nut retainer.
