Turn off the engine and ensure the vehicle is secure before working.
Clean the inner fender and wheel well area to remove dirt and debris.
Hold the mud flap up to the wheel well to check fit and alignment.
Use a marker or pencil to mark the mounting hole positions on the fender.
If no factory holes exist, carefully drill pilot holes at the marked points.
Align the mud flap with the holes and insert the provided screws or bolts.
Use a socket wrench or screwdriver to tighten the fasteners securely.
Repeat the process for the remaining mud flaps on all wheels.
Ensure each mud flap is level and does not interfere with tire movement.

After the drive, recheck the fasteners and adjust if necessary.
