Sound Deadening The 4Runner | HOW TO

[@Papolucho702]

Went looking for this type of video and yours pops up first lol

[@TRDJon]

I'm glad!

[@aky19832001]

That's actually pretty slick

[@Hobinator17]

Thanks for the tips & all your other content Jon, I got all my doors done & just finished the hatch today. The struts dont seem to be sagging on the hatch at all, maybe they beefed them up on the newer models. Shops were quoting me $350-500 to deaden 4 doors and there is no way they would have removed the plastic vapor barrier & covered every available square inch like I did. Took 3 full afternoons of work to do it right.

Love your content bro! So glad I found your channel! Thanks n keep it up!!

[@TRDJon]

Glad you enjoy it!

[@louispapas]

I did this last year. I did all my doors, (I removed the clear plastic weatherproofing and added the sound deadener there as well though), no need to worry, this stuff is butyl, which is 100% waterproof. This is one of the best upgrades you can do to a car. Planning to do the floors at some point too. Question: Did you had to replace the hatch shocks after this ? Great content on your channel btw, keep it up!

[@TRDJon]

I’m about to make a video about that. I am going to have to get better ones yes. Just noticed it the other day

[@Bodhi7007]

how about Oil spray? can it with stand oil coating ?

[@UtahNick71]

I think I will be doing the rear to try to lessen the sound/drone of the TRD exhaust

[@PandasUNITE]

Did it work? Did you do every inch of the read?

[@kevinberth8847]

Any difference in road noise? I’m assuming that to get a more “luxury car” feel inside you’d have to do a more thorough job of applying the sound deadening material. Thanks for the video!

[@TRDJon]

Only a little lest. I’m sure it would be better if it was done throughout the whole vehicle

[@mrpink3630]

there will indeed be a difference in road noise if you do it properly and not like this fuckhead

[@TRDJon]

Do you have nothing better to do then me a keyboard warrior looser? Geeeeezuus

[@nordicpride9708]

MLV doesn’t do much with respect to road noise. It will dampen panel resonance thus reducing noise. The stuff works, just doesn’t do what most people think it does. To reduce road noise you need to seal all holes, address air leaks and employ closed cell foam along with a few other approaches. Even this won’t silence a vehicle obviously, but it will approach that luxury vehicle quiet as a mouse kinda feel. The MLV does a lot to maximize your speakers. When applied correctly and coupled with closed cell foam, the results are nothing short of amazing.

Watched this video again as I plan on trying this over the weekend! Glad you clarified that this isn't a "competition" level goal. I've seen some other videos on sound deadening where others have covered almost every inch of the doors! Like you said, it depends on what your goals are. Having said that, are you planning to sound deadening any more areas in the doors after having test driven it for a few weeks now?

[@TRDJon]

Nope! Very solid so far! Be aware that the back hatch now doesn’t open all the way haha. The material is heavy!

[@JB-by8tw]

Blue TRD Jon Did you sound deaden the entire rear hatch, or just the speaker housing area? I may decide to just do the speaker area housing so this doesn't happen.

[@TRDJon]

I did the speaker area on the hatch as well. I did all doors just around the speaker

[@JB-by8tw]

Blue TRD Jon So just doing the speaker arear on the rear hatch made it so heavy as to not be able to lift all the way? Wow that deadening material must be pretty heavy. Maybe I'll just skip the rear hatch and do the deadening on the front and back doors

[@TRDJon]

Yea. I did more around it then the doors but yea. Very very thick

[@MrReaperv1]

You should always sound deaden-er to the plastic door panel also

[@TRDJon]

Thanks!!

[@damon323]

Great video Jon. So did it reduce road noise? I have fairly big tires and it’s pretty loud. Came that way when I bought it. Coming from a Lexus SUV, I was pretty spoiled in that respect. Im kinda getting from other comments here that it didn’t do much.

[@brandongilley4847]

Love your videos man keep it up!

[@TRDJon]

Appreciate it!

[@rogerokazaki3212]

Hey Trd John!! Will it affect the window goin up or down? thanks for all the tips!!

[@TRDJon]

Not at all

[@rogerokazaki3212]

@@TRDJon thanks so much for the reply TRD JON!! Last question, would it be easier to re-install the door panel with the window down rather than up? Im gonna be upgrading my front speakers this weekend! Thanks as always for all the content!!

[@TRDJon]

I don’t think it matters honestly. I just had it up for the sound dedtei

[@Bodhi7007]

Now if you live in rust belt and would want to periodically coat the door interiors with Oil to avoid rust, this application I guess will not help?

[@noicosounddeadener4641]

Hello, Blue TRD Jon!))) Awesome video! May we ask for your permission to share this footage as an instructional video for our customers and tag you? Thank you advance!

[@TRDJon]

Of course!

[@noicosounddeadener4641]

@@TRDJon Huge thanks to you!)

[@iq6840]

I just got some cans of bed liner paint. Works even better.

[@jrl1685]

What's the purpose of that plastic thing covering half of the door? Can i take it out? will it cause any damage in the long run?

[@TRDJon]

Not honestly sure. Maybe for road noise?

[@jesseoverlin4379]

Vapor barrier since water gets into the outer door

[@cmoreoverland6739]

How many square feet do you think you used?

[@TRDJon]

maybe like 5?

[@cmoreoverland6739]

@@TRDJon Cool. I have 10 sq ft thus I should have enough to make an impact.

[@blackackcl]

Jon's wife needs to go away more often, we get great KZbin content lol

[@TRDJon]

Hahahahaha right !!!???

[@Spartan_0916]

Why you only decided to do the inner sound deadening and not outer as well? travisarnold.com/sound-deadening-5th-gen-4runner/ Im about to install the same thing and now im not sure on doing the whole thing or just inside the door )

[@TRDJon]

Just didn’t feel the need at the time. Nothing really rattle to it at all when I tested either. But I does no harm at all doing all the door

[@graphguy]

I have my door lined with Kevlar :)

[@TRDJon]

What?????

[@graphguy]

@@TRDJon 48in sheet, level II protection = $450. Front driver and passenger sides :), it is very lightweight, maybe 1 lb per sq foot.

[@TRDJon]

No bad at all! Make it a lot quieter ?

[@graphguy]

@@TRDJon As I don't have big tires, I don't get a lot of external noise and I have had them for 5 year, so sort of forgot the previous sound level, but mostly it is rated for 9mm and 44mag :)

[@amyyern9507]

Graph guy, where did you buy the kevlar

[@Miklboy14]

%100 Waste of time and money. No need in any way to do this.

[@TRDJon]

Helped honestly reduce some road noise. I’m sure if you do the whole door that will help even more

[@Miklboy14]

@@TRDJon I keep forgetting I have a relatively stock 2019 SR5.Premium. Having bigger tires and rack certainly adds noise to your beautiful TRD. People that ride in mine are amazed at just how quiet it is. I installed an OEM Audio Plus system with so much clarity it literally makes people grin when they hear it for the first time. I didn't put any sound deadening material in and the stock head unit amplified with a sub sounds great. You are right though, it wasn't cheap! Speaker upgrades alone made a HUGE difference.

[@TRDJon]

I really wanna hear that system in person. I’m sure it is absolutely amazing!

[@louispapas]

@@Miklboy14 Good system but waaayyyy overpriced imo.

[@TRDJon]

Agreed. Paying for the convenience
