General Information
On some Cascadia vehicles built with full-length chassis side fairings, the rear quarter fenders may crack at the
fender mounting. A steel reinforcement is available to improve the durability of the quarter fender mounting. See
Fig. 1. When replacing a rear quarter fender, it is recommended that the additional steel reinforcements also be
installed.

Table 1, Quarter Fender Reinforcement Parts

Installation
1. Park the vehicle on a level surface, shut down the engine, and set the parking brake. Chock the tires.
2. Remove the damaged quarter fender from the mounting brackets.
3. Remove the fender flap from the damaged quarter fender.
4. Install the fender flap on the new quarter fender, leaving empty the two holes where the reinforcements will
attach. Tighten the fasteners 6 to 8 lbf·ft (8 to 11 N·m).
5. Position the quarter fender reinforcements on the new quarter fender. The longer toe of each reinforcement
should point inward. See Fig. 1 for orientation. Attach each reinforcement to the top of the fender at the
fender flap and hand-tighten the fasteners.
6. Insert the mounting bracket fasteners into the fender and the middle of each reinforcement to keep the reinforcements properly positioned.
7. Using the bottom holes in the reinforcements as guides, drill four holes into the quarter fender using a 1/4inch bit. While drilling, pay close attention to positioning to ensure the holes are at the tops of the fender
ridges.

IMPORTANT: Do not tighten more than the specified torque or the fastener may distort or damage the
quarter fenders.
8. Install the fasteners with the 1.25 OD washers touching the quarter fender plastic, and the .62 OD washers
between the larger washers and the capscrew head. Install the bracket-side nuts with .62 OD washers. See
Fig. 1. Tighten the fasteners 4 to 6 lbf·ft (5.5 to 8 N·m).
9. Tighten the two top fasteners 6 to 8 lbf·ft (8 to 11 N·m).
10. Install the quarter fender assembly onto the mounting bracket, and tighten the mounting fasteners 6 to 8
lbf·ft (8 to 11 N·m).
