Sound deadening/absorption - Wheel Wells

[flux-capacitor]

Has any one put sound deadening/ absorption material on the wheel well liners? If you have what was the process? Were the results worth it?

The goal is to reduce road noise. From what I can tell they are felt so CLD won’t adhere well to them. But I’ve been told 3M AU6002 w/ 3M 90 spray or Fiber Mat might work.

Not yet. I'm going to have to soon, though, because the tire noise from these KO3s has gotten ridiculous.

If you want tips on install, look at what the van life/camper van folks are doing. Lots of decent youtube videos and info on their forums.

I’ll have to take a look at that, my plan was to use a layer of CLD and then a layer of Fiber Mat. That plan went out the window when I learned the liner is felt on both sides

What about pulling the front wheel liner and applying sound deadening material like dynamat to the inside of the fender and then reinstalling the liner?

I haven’t had a chance to pull the liner out. But i don’t think there is any metal to put CLD on in between the engine bay and wheel well. From what I’ve seen the only barrier between the engine bay and wheel is the wheel well liner.

I wonder if the interior sound could be reduced by deadening the front fender itself and all other metal surfaces inside the wheel well?

I also wonder if the deadening sheets aren’t sticky enough to adhere to the inside of the liner. That stuff is really sticky.

I’m thinking about trying both using kilmat from Amazon. Pretty inexpensive for a test and I have like 7 sheets remaining from another project.

I’ve also heard deadening the inside of the skid plate may help with interior noise too. I’m not sure its about “blocking” noise as much as reducing surfaces that bounce sound. However, I know nothing about acoustics but I have found in my music room that softening hard surfaces in the room have helped the stage.

I finished my project today and I’m very satisfied with the results.

1 removed the front wheel liners
2 applied left over Siless Max 120 mil on the inside of the front fenders. I bet it looks real pretty from the inside!
3 applied Siless Liner 157 (4 mm) mil on the inside of the felt liners. No problem with it sticking.
4 reinstalled the liners and went for a drive.
5 noticeable difference. Does a great job of toning down the KO3’s on the road.

Would I do this on a truck that is primarily used for off road fun in the sun? Probably not.

But for me, it now provides me with the sound (or lack of sound) I have been chasing while I do what I do with my truck while doing it quickly.

Do you have any pics of install? Specifically how you went about installing it on the front fender. How much did it reduce the road noise in your option? Sounds like it would be worthwhile!

No pics. Just cover the inside of the fender as much as you can with the butyl (you’ll be doing this blind) and cover the inside of the liner with the foam. I have no idea how to determine the amount of reduction but I already had the butyl panels and the foam was cheap. Takes a little less than 9 SF of the foam per liner. Big difference for me and I enjoy projects.

Note that I already have the doors, roof and back bulkhead done. This is the latest in my quest for sound deadening the RR. I think I am now done with that effort.

Another note, removing the wheel before the liner would make it easier to do the fender but I didn’t want to mess with that.

I had mine done, we pulled the liners down and used the scrap dynamatt materials I used on my doors and roof. Plus used a boom mat spray over the top of the inner fenders then reinstalled the liners. It’s all hidden and I do believe it has been a noticeable improvement.

Still if you have noisy mud terrain tires you’re going to hear them.

I try and always keep tire tread design in mind when shopping for tires. Some ATs and MTs are quieter then others and most any of them get noisy over time as they wear down.

Did you test with each part additively by chance? Other people have mentioned doors are a biggest bang for your buck with ease of installation vs outcome. Would you agree with that given you've done them all?

Yes, I agree. Doors first by far. I also think they were the easiest.

How difficult is it to remove the wheel liners? Any tips or tricks?
