Hood Bulge Howling after installing light bar.

I installed a 40” S8 Baja Design light bar in my 2020 CM hood bulge using the SDHQ light bar mount made specifically for the Baja Design light bar. Using the SDHQ made specifically for the 40” S8 Baja Design light bar, the instructions says to cut three 3-1/4” holes to access the mounting screws for the hood bulge. Now I notice when. there’s a little wind or at high speeds I get a howling noise because of the air flow going through the hood bulge, any body experience this and have a fix for it?

 

Is this the 40” Baja designs light bar with the SDHQ mount?

 

Yeah it is.

 

These are the three access holes that I drilled per SDHQ instructions.

 

How about putting some (painter's) tape to cover the holes and see if that stops that howling? If so, replace the tape with some closed rubber grommets:

 

@713Tundra good idea, I'll try the painters tape first. Where did you find those closes rubber grommets? Thanks

 

Amazon or Ace

 

I dont have any howling noises with mine. If the painters tape doesn't stick, use the foil tape that's used for air conditioning. Lowes or HD carries it.
