into the rocker panel protector and then into the
threaded hole in the side step bracket.
Notice: Threading the knob into the side step and

The step could fall off the vehicle and be damaged.
Always thread the knob through the rocker panel
first. After the knob is installed, try moving the step
left and right to be sure the step is secure.
5. Hand-tighten the knob by turning it clockwise until it
is seated against the rocker panel protector bracket
and then tighten it to 10 lb ft (13.5
Y ) with the
tool as shown.
