Suppose you had a 2014 Explorer® in the
bay with some rear end damage. You repair it as good as new
following OEM repair procedures and deliver it to the customer.
She looks at the repair and pronounces it perfect. Later in the
week, she drives back to the shop complaining about a whistling
or buzzing coming from the FRONT of the vehicle. She insists that
it must be related to your repair. But the original damage was
way back there at the other end of the Explorer.
Playing a hunch, you check for a technical service bulletin (TSB)
from Ford® that

you discover that the whistle/buzz-type noise is a known issue,

Is the whistle or buzz-type noise present at highway speeds
only with the masking tape removed?
Yes – proceed to Step 3.
No – this article does not apply. Refer to manufacturer’s
repair information to diagnose the condition.
Remove the front cowl panel grille cover.
Using a straightedge, measure the distance from the
windshield glass surface to the cowl sheet metal at each of the
seven mounting holes for the front cowl panel grille cover.
