Technical Service Bulletin M3411302012 — 2009 RAM 1500

Advanced Field Action Communication ? M3411302012 Chrysler Group LLC (Chrysler) announced a safety recall on certain 2009 and 2010 model year (DS) Ram 1500 series trucks and (ND) Dodge Dakota trucks equipped with a Chrysler built 9.25? rear axle. The above vehicles may have been built without an adhesive patch on the rear axle pinion nut threads. The lack of this adhesive patch could allow the rear axle pinion nut to loosen and/or the rear driveshaft to separate from the rear axle. A loose pinion nut could cause the rear axle to seize and a separated driveshaft could cause a loss of motive power. Excessive loosening of the rear axle pinion nut can allow the pinion gear to be drawn into the rear axle assembly, resulting in rear axle lock-up. Chrysler will conduct a voluntary safety recall on all affected vehicles to install a rear axle pinion nut retainer. Unfortunately, the parts required to provide a permanent remedy for this condition are currently not available. Chrysler anticipates the remedy parts will be available within the 1st quarter of 2013. An interim notification letter is being mailed to all involved vehicle owners. Chrysler is required by Federal law to inform all involved vehicle owners of a potential vehicle safety defect.
