NOTE:
Use a 4-mm Allen wrench to remove the front-door hinge bodies from the

steps:
1 Remove the front door (see "Removing the Front Door" on page 8).
2 Remove the side panels (see "Removing and Replacing the Side Panels" on
page 12).
3 Reverse the top hinge body.
a Pull the hinge pin upward slightly so that you can access the retention
clip (see Figure 1-6).
b Using the needle-nose pliers, remove the retention clip, and slide
the hinge pin out of the hinge body.
