Dana has made design changes to the Helical Gear Thrust Washer and Wheel Differential Cases in the
models listed above. These new design features enhance the overall performance of each segment of the
axle the parts are located in (Power Divider Section and Wheel Differential Section). Each change is
detailed below and was implemented in production units starting in mid 2007.
SERVICE PARTS EFFECT:
The original design parts and new design parts are 100% interchangeable. All kits sold through service
containing the original parts will move to the new design parts as individual inventories are depleted.
