Cab wind and road noise

[okie4570]

So finally after 50k miles I finally attempted to reduce some of this noise. They make some $500 and up sound dampening and sound proofing precut kits for this, but I ventured out on my own. I spent a total of $38.

I'm pretty much appalled at the lack of sound deadening and proofing this bronco has. It is literally a tin can. I bought some 5 mil self adhesive sheets, a pair of scissors, some glass cleaner and a rag and off I went. Pulled the door faces off and covered everything I could. Pulled the back side panels off and covered everything I could. Beginning dB going down the highway at 65mph with no wind was 86db. After the sound dampening and proofing it's now an awesome 74db which is absolute day and night difference. Took about 1.5 hours to do it all. Look how open everything is under the plastic side panels right above the tires. Next I'm going to bed line the inside of the tire wells on the top side. Major bonus points with the wife since this is her daily driver lol.

Good job! I am not a 6G guy but I drive one usually 2x/week. The NOISE and fitment is terrible IMO for a new car. My buddy has one and I've put thousands of miles on it and for a SUV that came out in a 4 door so they (Ford) could sell 3.5- 4x as many of them (as per 6G head engineer who told me in Moab when they road/wheeled with us ) to soccer moms than 2 doors I can't believe they couldn't quiet down the wind noise. It sucks.

74 db from 86db is huge!! More than 10times more powerful (louder). 90% of American don't understand the db scale. An earthquake at 7.0 is 10X more powerful than a 6.0 earthquake. Somebody here will get the exact #. Great job.

Wow! So you just mainly covered the openings below the top of the bed rails and the gap in front of the wheel well? That is an incredible reduction in noise as @nvrstuk points out.

I installed the Hot Head liner with sound deadening and was a bit disappointed at the minimal difference it made. Looks like a new project I need to add on my project list!!

Yes sir, and I'll prob go back and stuff those cavities with some kind of insulation and reseal for more improvement. Those panels pop off easily. We're still running the original tires with 50k miles on them as well, they're noisy imo. New tires going on friday.

The wind noise must be worse in the 4D than the 2D because we don't have a lot of that, but had LOTS of road noise. Not sure if it's the additional panel seams in the 4D or what but wind noise on our 2D isn't bad at all imo.

4 door 6G road noise is unacceptable IMO for any new car made in the USA. Not talking an old Trabant or something! lol

Maybe it's just this one but ...

There is no doubt they are noisy inside. But no worse than any Jeep I have been in. I agree a little sound deadening would be nice. I am surprised you got such major results with such minimal coverage. Maybe another project I will need to do in the future.

Adding 2 layers of 80mil Kilmat and 2 layers of 4mm closed cell foam have made my old trucks very civilized inside, also easier to heat and cool.

I've not been in any other new bronco other than our own so I don't have any others to compare to. My daughter's 07' Jk is WAY quieter than our 22' Badlands, both in road noise and wind noise. That back end behind those panels is just like a snare drum, tap on it with your finger and it rings and pings. It's dead now though.
