Makes you wonder just what the hell Ford was doing during development time.

Op, any issues with drainage post mods?

Thank you!

Great write up! I’ve done a lot of wind noise mitigation to my top, but it mostly involved stuffing crap from my wife’s craft room into gaps I could find. With topless season about to return, time to make those more permanent, I will follow your guide. Although I’m not sure about the windshield one, that is a drain channel. Will need to look at that one closely. Thanks again.

So, we know these are Built Wild... but my wife didn't appreciate it sounding like a hurricane everyday. Who wouldn't want to hear the subtle guitar, bass, drums and notes of your favorite music on the sound system for which you paid? After reading 4+ threads and looking at various modifications people made, I decided to create a single guide here of everything I did to reduce the interior noise. The ideas are not all my own, and credit is due to those individuals whose brilliance came first. Shoutouts to some of those brilliant individuals- jlatigo, mountainbronco, Geo2 and more that I can't put my finger on.

My family says it's significantly quieter now, and I tend to do whatever they say. Hope this helps enhance your ride!

Total cost is about $75. Total install time is ~1 hour if your hard top is already off. If it's not off, what are you waiting for?

Specs

• 4 Door- most of the below applies to both 2 and 4 door models
• Wildtrak, Sasquatch
• MIC Hard Top

Grocery List
(These are not affiliate links. I don't receive anything from you clicking on them!)

1. KX Automotive Universal New Weather Stripping EPDM Rubber Seal Strip D-Shape (20')
2. Duck Brand Self Adhesive Foam Weatherstrip Seal for Extra Large Gaps, 3/4-In x 1/2-In (1 roll)
3. KX Automotive Universal D-Shape Door Seal 0.47" Height X 0.55" Width Weather Stripping (10')
4. Automotive Weather Stripping Door Window Rubber Seal Strip Z Shape (Buy the "Z" Shape- you only need about 3' of this, so you'll have a lot left over)
5. Armacell 3/4 in. x 6 ft. Rubber Self-Seal Pipe Wrap Insulation (You need 2 of these)

General Install Notes

• Clean all surfaces before attempting to stick the adhesive
• Let the adhesive bond- i.e. flex your muscles and secure firmly!
• Use a regular scissors to cut things to length- most are approximate, and size doesn't matter as much (right?). The Z Shape strip is more visible, and you probably want to measure (hint, 15.5").
• Some seals are hidden, and some are visible... take your time. If you screw up, cut a new strip.

From the front of the vehicle working to the back...

Windshield

• In the front channel, adhere #1 in the Grocery List inside the full length of the channel.
• Cut 4 short strips of #2 and stick them 2 each, side by side, vertically in the ends of the channel.
• All of this is hidden with the top on. With the top off, it will either look factory installed or like a small kid used the scissors if you don't cut straight. I have both results.

Front Panels

• Use the #1 stripping for all of these.
• Primary guidance is to adhere the middle strip that goes on the Driver’s Front Panel to the slightly raised portion of the roof. Don’t adhere it to the top/roof section as it won’t allow the panel to close enough. It also makes for a cleaner look if you install on the raised portion.
• The two strips that face the windshield are not visible. The strip that runs between the two panels is minimally visible.

Mid Panel

• Secure #3 along the length of the mid panel. This is the curved side of the panel that faces towards the back.
• Snuggle the stripping right along the edge and you'll look like a pro. This is visible from the inside once installed.
• Super easy, right?

Rear Panel

• This is the fun one and makes a big sound impact!
• The picture is probably the best explanation of what goes where.
• I'm not sure if the top most #3 install is needed- and I forgot to take another picture of it properly adhered. It basically curves along a small section on top. I had some extra stripping, so I used it.
• The small square of #2 goes on top of a similar, but thinner material that Ford already has in that same place.
• The Z Shape #4 is great stuff, and I think makes the exterior even look a little sleek (no one ever described a Bronco as sleek, right?). I'd measure this one and cut accordingly- I did 15.5". Adhere it right along the edge of the panel. This helps with wind noise by sealing the gap between the frame of the Bronco and the rear panel.
• This is not visible except for #4 (Z Shape stripping).

Exterior View:

To Pool Noodle or to Wrap Your Pipe

• I saw various opinions on which material worked best, which ones disintegrated in the elements, how to secure, etc.
• I decided to use the rubber Armacell pipe wrap - #5 on the Grocery List. It comes in a 6’ length, and I left it as-is.
• I peeled off the self-adhering tape and stuck it to itself.
• Rather than figure out how to secure it with the top off and/or how to not make it look bad… I decided I’d simply lay it in the roof gutter when I put the hard top on. Otherwise, it will sit in storage in my garage if the top is off.
• We’ll see if it lasts- easy and inexpensive to replace.

So that's about it. I suggest ordering everything and installing all at once when you have the roof off vs string betting the process.

Happy Sound Dampening!

WOW........thats some great effort on your part, well documented and laid out!

Great post!!!!
Thanks for sharing!
I'm adding this to my list and moving it to the top!

I don't have mine yet to try but what amazes me is that your $75 in material would have cost Ford less than $5 and resolved the issue to begin with.

So many posts seem to be caused by Ford letting the bean counters dictate so much to reach a sticker price or a larger profit margin. Anyrate, thanks for gathering all the info together in one go by.

I agree. The total added cost to make the top that much more soundproof, would probably be minimal. Quality doesn’t cost, it pays.

Thank you.

Op, any issues with drainage post mods?

I took it through a car wash today with no issues. Maybe I’m missing something about where/how it drains?

Pro tip: if you think your bronco is too loud remove your doors and top for a few weeks during summer. When you put them back on your thoughts on the problem will be solved.

Genius. Why didn’t I think of this and save the $75?! I’ll credit you in my next post.

Nope, my Bronco is doing equally well with similar mods. Zero downsides/drainage issues.

Doing this makes a HUGE difference, my Bronco is quieter on the road than my girlfriend's 2021 Honda CR-V EX-L.

Ah yes! You were one of the brilliant forefathers I learned from. Credit is due.

I’m starting to think that there Is a direct correlation between one’s region and one’s wind noise experience. To wit, people in big western states with lots of prevailing wind & high speed interstate highways say “Loud”, while people in eastern sheltered woodlands with low-speed twisty local roads say “Sounds fine.“
