Description and operation



The DN uses a three section frame design. The ends of the center section are swaged to fit into the front and rear sections. The front, center, and rear sections are welded together. The frame is serviced as a complete unit only.


The frame is designed to absorb and dissipate flexing and twisting due to acceleration, braking, cornering and road surface variances without bending when subjected to normal driving conditions. The frame is the mounting platform for the following systems and components:

  • Engine, transmission, and transfer case.
  • Exhaust system and heat shields.
  • Front and rear bumper systems.
  • Front and rear suspension systems.
  •  Front end sheet metal and radiator closure panel.
  •  Fuel cell and fuel line tubing.
  • Parking brake.
  •  Steering gear and linkage.
  • Skid plate.
  • Spare tire winch.
  • Trailer hitch.

 Vehicle body.
