According to the Washington post, The National Highway Traffic Safety Administration is looking into 2009-2010 Ram pickups because the rear wheels could lock up.
Some sources say that the issue may involve a pinion coming loose in the rear differential that could cause the rear driveshaft to lock up.
The investigation affects around 230,000 trucks. No specific trims have been mentioned.
No official recall has been announced yet, and Chrysler is cooperating with the government, the story said.
