overhang the end of the frame and interfere with removing the assembled bumper with brackets. On
these models, release the plastic clips attaching the plastic cover to the steel bumper. Remove cover
and hardware attaching the bumper to the bumper brackets. With assistance, remove the outer steel
bumper, then slide the brackets out of the ends of the frame.
3. With assistance, position the Bumper Assembly up to and into the end of the frame. Temporarily
support the weight of the Bumper. WARNING: To avoid possible injury or damage to the vehicle, do not
proceed until the Bumper is fully and safely supported.
