Whistling after air dam removal. Help

[Swizzard24]

So at about 30 mph to 52 mph getting whistling noise. Put bolts back into holes after removal. Looking at lower suspension arms as possible cause. What has anyone done? Help needed.

I was just changing my truck's oil yesterday and looking at the plastic plugs that stop the noise. Do a search on the forum where you can find the plugs and placements in the control arms that will stop that.

If you're cheap like me, you can cover the holes up with duct tape and it will fix it.

My wife, who hears EVERYTHING, has never said a peep and I don't hear anything.
I didn't plug any holes, but seem to remember tucking the felt type material under other plastic or something before re-installing bolts.

I had the Whistling issue after I removed my air dam (2025 TRD SPORT) and installed plugs on the lower suspension arms and that solved the noise issue. I just covered the 19 mm holes on the arms and fix it. I used these from Amazon, and they worked great!
