I thought we were all friends......You guys/gals are funny..... Should I post my mud flaps????? Once I put them on.... lol

On the WallyWorld site:
Installation:
It is easy and fast. Align with existing holes, secure with screws and snaps. You will get 7 screws with threaded washers (including 1 set spare) , which will provide a sturdy hold and make it less likely to fall off ...
Good to know it's less likely to fall off...
Also would be interesting to see what "threaded washers" are..
Maybe they are like bolts and nuts...

Don’t use the included hardware! If you over tighten the bolts they can dent your hood. I spent a good amount of trial and error time finding plastic fasteners that work with the existing hood structure.

That actually looks pretty good.

My tablet is old........It doesn't do a lot of things.... i'm glad it does the stuff it do do.... lol

Thanks for that 411, but I'm planning on eliminating any chance of damage by avoiding the install..

And i'm not pushing a product.... I like the product that's all. We're friends.....

If my hood were to vibrate enough to cause a noise that I could hear within my cab I would not be worried about reducing the noise with an add on. I would have more worries. I have not at this point read any complaints about this being an issue but the earliest trucks are getting older.

I'm talking about minor noise or vibrations that happen in many places throughout the vehicle that are almost imperceptible. They cause no major problems. A large metal panel will always vibrate to some extent.

There many parts on any vehicle that function to dampen sound vibration, including sprayable material applied right after paint (see link):

Most vehicles use this stuff, especially on the underbody. Luxury cars almost always have a Hood Pad in addition, but the Maverick is an entry level model. The pad may dampen the Hood vibration.

This Soundskins site has a pretty good explanation. The first picture points to "trunk lid resonance", for example. https://soundskinsglobal.com/blogs/sound-news/what-causes-hidden-vibrations-inside-car-panels

Hidden panel vibration is one of the most common reasons vehicles feel noisy, cheap, or tiring over time. Understanding where these vibrations come from explains why surface-level fixes rarely work and why proper sound deadening panels make such a noticeable difference.

Hidden vibrations occur when:

• Energy enters thin metal surfaces
• Panels lack mass or damping
• Large flat areas act like resonators
• Sound waves excite the structure itself

Nothing has to be broken for this to happen. It’s a physics problem, not a mechanical failure.

Not all panels behave the same way. Larger, flatter panels vibrate more easily than small, curved ones.

Common vibration-prone areas include:

• Door outer skins
• Roof panels
• Floor sections between structural supports
• Rear quarter panels

Flat metal behaves like a drum skin. The larger the surface, the easier it is to excite with vibration. Curved or reinforced panels resist movement better, which is why some parts of the car remain quiet while others don’t.

Just having a little fun......again...... i'm happy with the product

And as I go to bed, for the people that's dropping knowledge......... Thank you....

I understand sound deadening but we arent going down a rabbit hole about how that works, we are talking about engine noise and an add-on that is being said to suppress it. I would imagine any sound deadening would be primarily in the firewall or the doors for any real concerns.

Didn't someone test this with a temp gun and found out it did NOTHING? Also with a db meter, with almost zero difference. Thus, it's more of a decoration than anything. But some guys like to decorate, so there's that.

Color me weird, but I like to hear all I can from under the hood when I'm in the driver's seat -particularly in this hybrid. Like to be aware when ICE kicks on/off on residential streets, and the comfortable hum/growl at cruising speed on the highway, same as telling me 'all is well'. It doesn't seem like a particularly noisy or annoying powertrain compared to other vehicles I've driven. Perhaps I'll change my mind after a few longer trips.

I’m the same with my EB. Listening to the real mechanical sounds & the ESE is second only to keeping my eyes on the road.

ESE = Electronic Sound Enhancement

No, by saying that you demonstrate that you don't understand that we are also talking about vibrational noise from the panel. Because of your original question, my point is that the pad can make a difference in 2 ways: insulation for noise escaping the engine compartment as well as dampening any vibrational noise from the Hood. Did you read the SoundSkins link?

I am still not convinced but your profile pic is making more sense now lol.

I don't care if you understand or not, maybe others will be interested in the science of it rather than whatever it is you are guessing about.
