FRAME AND BUMPERS
DESCRIPTION
The bumpers on the Jeep Cherokee are made up of
the main bumper beam, the end caps, air deflector
(front bumper) and mounting brackets. Some Chero-
kee models also have a tow hook support bracket.
FRAME
DESCRIPTION
Jeep Cherokee vehicles do not have a conventional
frame. They are constructed as a unitized body and
frame. Jeep unibodies are constructed from special
high strength steel and coated metals. This process
reduces weight and provides strength to withstand
the forces applied against structural members. The
structural members provide a unibody that has great
structural strength.
OPERATION
The bumpers are fastened to the unitized body
frame rails. The bumper end caps are fastened to the
bumper and the body side sheet metal.
