Chrysler Group  is recalling 361,819 vehicles over concerns that a rear axle fastener could fail. This is a supplementmental recall linked to an earlier campaign conducted to upgrade light-truck axles.

The affected models are 2009 Dodge Durangos and Chrysler Aspens, 2009-2011 Dodge Dakotas and 2009-2012 Ram 1500 pickups.

Chrysler has determined that some rear axles were assembled with a fastener that can loosen over time and ultimately fail. Chrysler Group dealers will install a retainer to secure the fastener at no cost to the customer.

Owners of the affected models will be notified if their vehicle is included in the campaign.

The company says it is unaware of any injuries associated with failure of the fastener.
