After upgrading to First Edition mud flaps I now hear “flapping like” wind noise at highway speed. “Flapping” noise is subtle but present.

Has anyone else experienced this type of wind noise with their FE mud flaps?

If yes why?

  • No flappin.
  • Adds flaps. Now flappin.

Back to the lab!
I will either have my wife drive along side of the LC and watch the mud flaps at highway speed or set up a GoPro aimed at the mud flaps and film the mud flaps while I am on the highway.

I will post the outcome.
 
I have JAOS flaps and do not hear any "flapping". Did you try to adjust the tension belts? Might be they are too loose...
I will check that out.

Thank you.
 
If flapping in the breeze...
Check for some faults in in the instructions...

I’m going to double check later today and report back.

Thank you.
 
What are we reporting here :LOL:

Last known good was pre-flap install. Post flap install we have flapping. For one reason or another, in the words of @RideWithYanu, your flaps be “flappin.”
 
Yeah, thank you.

I need to perform additional troubleshooting to determine the cause of the new noise then come up with a solution.

Thank you.
 
Ah

Ha ha
 
No noise from mine.
 
I wonder if this has anything to do with the damn single pane side glass windows....
I don’t know. I suppose it’s possible.
 
On the serious side, the usual culprit on these FE flaps is the tension straps running a touch loose, like Viktor said, or one of the push pins not fully seated so the flap sits proud of the body and catches the air. A subtle flap at highway speed is almost always aerodynamic buffeting off the trailing edge rather than anything about to fall off. Snug the straps up a notch and it normally goes quiet.
