94-02 Front axles are Dana 60's...
94-02 Rear Axles in Automatic equipped trucks were Dana 70's.
94-02 Rear Axles in stick equipped trucks were Dana 80's.
The exceptions are the Dually's which ALL had Dana 80's in the rear.

In 2001.5-02 the rear axles,Both the Dana 70 and Dana 80,were equipped with disc brakes.

In 02 most all of the front Dana 60's were not equipped with CAD's(center axle disconnects).
