One problem related to axle shaft has been reported for the 2005 Dodge Dakota. The most recently reported issues are listed below.
There's an existing TSB (Chrysler/Dodge 05-002-06 supersedes 05-004-05) that covers the repair of the rear axle shafts and braking system. There was a defect in the design of the parts that can cause the rear wheels not to brake and can cause the driver to lose control of the vehicle at highway speeds. Dodge issued the two aforementioned tsbs to correct the issue, but it wasn't widely performed. Lots of 05 and 06 Dakotas with the defect are still on the road.
