I heard somewhere that the higher-end pats had sound deadening material in the fenders. might want to try that, then all your doors. If you really wanna go all out, take out the front seats and center console, rip up the carpet, and mat the entire floor. THAT would help a lot.

 

Yes, I'm doing the floor as soon as I finish the 2 front doors. If I need more, the fenders (or wheel wells) will be next, although I do have a "higher end" Patriot....then the spare tire area after that.

If that doesn't help...I'm done!

 

I sound proofed the entire jeep, with a solid kayer. It made a huge difference but it's still quiet loud. Plus you can hear the cvt whine still.

I've done all doors and the hatch back with Fat Mat. It is allot quieter. I did both inner door and outer door skin. I plan to-do the floor and roof soon.

One suggestion I have for you is to make sure you also add a layer to the back of the plastic interior pieces before you put them on. I did that to all of mine and it helped with the rattles.

Now is it competently quiet? No, but it's better then stock. I would not have it any other way.

 

I too plan to soundproof my Patriot (it's on my list of a million other things I want to do lol). I have a similar issue with background noise and my hearing.

 

Well I finished the front doors and took it for a test drive and I could hear a difference already. (but it wasn't enough to solve my problem) Now have the front seats removed and am covering the floorboard. I'm betting this will do the trick.
I'll let you know later this afternoon.

 

I would suggest investing in these as well. You might break something prying around with a flat head screw driver.

So I did the front doors, floorboard back to the rear seats, and removed the plastics over the front tires and put some on the metal part of the fenderwells.

Seems the only thing I can hear now is the slight whine of the CVT and the blasted tires when I get up some speed. I'm a bit disappointed that I couldn't quiet the tire noise but overall the car sounds good now. I just got these tires so getting new quiet michelins or the like isn't in the equation.
As I said before, someone with normal hearing would be real happy, but for me it didn't quite do the trick.
I'll be sure to research and get the quietest tires available when these wear out.
Meanwhile, at least I can hear well enough to have a conversation or listen to the radio and not have to have it too loud for anyone else.

The floorboard was actually easier to do that the door panels, they were a pain to get back together. I took the front seats out and the side floor trim and just pulled the carpet back without having to remove it, (in case anyone is planning to do this.

I have enough fatmat left over that I'll probably go ahead and use it in the spare tire well when I get some spare time.

 

How do you guys remove the door panels? Mines an 08 and I tried to remove it till I saw the friggin window motor was attached to the inner panel. Stupid design imo lol

 

Motor was attached on my 2012 too...basically I just started with removing the armrest and then a couple screws at the bottom of the panel. Also have to remove the speaker. As I worked the panel off I just kept finding whatever was still holding it on and undid them till the panel was free.

Here's an old thread with pictures that I looked at before starting but didn't use while I was doing the work.

OK, I took the Patriot on a 500 mile trip to the NC mountains this weekend...I was fairly disappointed that the tire whine was still bothersome on the highway after doing the front doors, floorboard and inside the wheelwells under the plastic on the front.

I had 4 sheets left over so today I did the spare tire area and then managed to slip a couple of fairly good sized rectangles on the upper fenderwells from under the hood, in that little space at the top of each fender. Had to use a large angled egg turner to press down the material along the sides inside the fender.
Took it to the grocery store just a bit ago and most of the tire whine is now gone! I can still hear it but it's quiet enough that it's no longer bothersome to my strange hearing problem. I'm a very happy boy now!

So I guess if you're soundproofing for tire noise, be sure to do the front fenderwells top and bottom. Not sure how much the spare tire area helped, but I believe (some day) when I get quiet tires this Jeep is going to sound more like my wife's rogue inside. (Which is very quiet)

FWIW I averaged 29.5 mpg on the highway with speeds mostly 65 and under.

 

I was honestly really surprised how quiet my 2014 5 speed patriot was when I picked it up. I have driven hundreds of older CVT calibers/compass/patriots and thought they were ridiculously noisy. I forgot to shift it sometimes because I couldn't hear the engine. Look down and I'm doing 5800rpms lol.

 

I do that so much when I'm driving tiptronic lol. the first week I had my Pat i was driving down a bypass going 45 and my buddy mentioned how much the thing vibrated.... then I looked down and I was in first :doh:

 

I was just thinking, what if you removed your front fenders and sprayed the inside with expandable foam? Shouldn't be that hard to do.. Maybe do the rear hatch too

 

It would probably help....but this stickon stuff (I used fatmat) is really easy and probably a lot less messy.

 

yea, but any sound deadening material is kinda expensive. I would rather spend $10 on a couple cans of expanding foam, and just smear that over the surface than spend about $40 for the same effect. I'm thinking economical. It's not really worth putting a lot of money into a cheaply-built vehicle.

 

I noticed that the newer model years had sound insulation on the underside of the removable cargo "Ultra Floor" so I glued some generic color matching automotive floor carpet from some place like Pep Boys on the bottom of my 09 Ultra Floor. The newer models also had long square sound baffles between the sides of the spare tire well liner and the metal body panel so I took the rest of the generic carpet, rolled it up and stuck it in there. I am not sure it helped a whole lot but figured the factory knew what they were doing and it wouldn't hurt. I would have ordered the sound baffles but getting the part numbers of something like that can be a hassle.

 

I would not try spray foam. Just spend the money on quality sound proofing. Sound deadening works, which is why it costs quite a bit.

They use spray foam from the factory. It's a special kind of spray foam that is much denser though.

 

True...I saw some of that while doing mine. Also saw some of the mat stick on type. But it was all used very sparingly.....probably just enough to keep the big vibrations down.

 

The road noise doesn't bother me or I dont know what a quiet vehicle sounds like . But I do want to put some of that stuff in the door panels so they don't sound like tin when you close the doors.

 

EXACTLY! One major thing that bugs me... these things are built like Honduhs. beer-can's on wheels. I took off my hatch panels to find out if I can reduce subwoofer rattle and the whole panel just echo's any vibration put on it.

 

Gotta remember that these are econo jeeps based on the caliber that is based on a mitsubishi..

 

In other words.... Cheap! By design.... Jeep, by capability!
