Hood Vibrating / Vibration Fix Solution = Weather Stripping Rubber Trim!

[Keroppi]

Here's a hood vibration solution that's been tested and works. Just install this weather stripping / rubber trim seal gasket to this area under your hood.

Interesting possible solution....

I wonder if this edge is not sealed for a reason by Toyota (other than being cheap on the build)?

 

[Seoabdalla]

That’s an interesting solution …
Would def be down to install if it’s not going to affect any heating elements

Can you make a short video on how you installed it and the before and after hood vibration is resolved. Would be nice to see a good tutorial of this since most everyone is experiencing this issue. A cheap and easy fix would be great to see.
I am also thinking that by sealing that area will effect the cooling of the motor. It is looking as if Toyota engineers possibly left that space for heat to exit after air passes across the engine bay. I would like to see if you could monitor engine and water temperature before and after to see if there are significant changes.
Thanks

Why does hood vibration need a solution? It's not even a defect.
It's a huge sheet of aluminum designed to crumble like paper in an accident, it's normal it has flex to it.

Simplest thought would be that you'll wear off the paint as the rubber is contacting the hood.

The vibration allows me to feel like I'm off-roading on the highway! HA! HA! JK - seriously though, when I first picked up my new TRD Pro that was one of the first things I noticed so I checked out how the hood fit, the seals, etc. My first thought was what a few of you have stated - area designed to vent off heat (not so much of letting air in based on dynamic motion flow / Laminar Flow). I'm not touching it.

Fantastic Solution, will be doing this too

Great Work!

Gent's, might not want to completely seal in the hood. This is what I found: I'm quoting:

" Yes, those gaps are very likely an intentional design feature to aid in heat dissipation, airflow regulation, or both—especially given the TRD Pro’s off-road and performance focus.
If the gaps were completely sealed, it could trap heat and contribute to wear or reduced performance of nearby components like" :

• The battery
• Wiring harnesses
• Brake booster
• Intake manifold sensors

Why this makes sense for the TRD Pro

• The TRD Pro is an off-road performance variant, so Toyota engineers likely prioritized function over cosmetics.
• Venting hot air is particularly useful when crawling in rugged terrain, where overheating components (like the transmission or power steering) is a risk.
• The cowl area is a safe spot to release heat without risking water ingestion or dust intrusion into sensitive components.

Heat Ventilation Design

Toyota may have designed those gaps or open channels to:

1. Vent hot airrising from the engine bay:
   • Hot air naturally rises, and a vented cowl area helps it escape upward, reducing engine bay heat soak.
   • Especially beneficial during off-roading or slow-speed climbs, where airflow is limited.
2. Reduce under-hood pressure:
   • Controlled venting can stabilize airflow and reduce lift or turbulence at high speeds.
3. Improve windshield defrost performance:
   • Some vehicles allow warm air to escape into the cowl region, aiding defrost efficiency and reducing fog-up during engine warm-up.

The gaps near the top of the hood on the 2025 Toyota 4Runner TRD Pro—especially near the windshield/cowl area—are intentional and functional, not a design oversight.

Maybe a short piece at mid-span is all that is needed.

Anyone notice the front door wind noises?
I have a solution for this too.

MD Auto & Marine Rubber Weatherseal.

It comes in 5/16th and has two strips in one each on the front door, place it on the outer edge of the current rubber molding on the body. Reduces wind noise significantly.

I really appreciate forums like this where enthusiasts can discuss issues, share ideas, and help each other find solutions for the vehicles we all enjoy. I’ve just hit 300 miles on my 2025 4Runner Pro—my sixth 4Runner, going all the way back to a 4th gen V8.

One of the first things I noticed on the drive home from the dealership was the hood flexing near the base of the windshield at speeds over 65 mph. At first, I brushed it off because I’m genuinely excited about this new 6th gen.

I recently installed the weather stripping that @Keroppi recommended—it took about 8 minutes—and I’m happy to report that it completely resolved the hood flex issue.

Thanks again!

I installed the weather stripping that @Keroppi suggested and it fit really great. I purposely left the outer 3” open where the metal edge bends. I wanted to make sure that some heat / air had somewhere to escape. Seems that it will flow on the outside and where the windshield sprayer nozzles are located too. I haven’t hit highway speeds but I am still seeing a little vibration over 30 mph but it appears to be reduced from how it was. I will report back later after it hit higher speeds.

following...!
To reduce wind noise: Is there a solution for the gap between front fender and door? I know there's a part number Weather Strip 67865-AK020 and 67866-AK020, however, it's for the 2024+ Tacoma. Anyone knows what's the equivalent for the 2025 4Runner?
