2021,22,23 Vs 2024 Interior Noise

I drove a 2023 with a decibel meter , then my 2024 on the same 70mph cruise at my dealership to measure the difference in the carpet, side glass , firewall insulation and window frame insulation. It was a 3dB reduction. Both were hardtops. Without the meter you could tell something good was completed. Wife was on both tests and really noticed the improvement. However, we would have bought and enjoyed either one as “louder” was not a deal breaker.

And both of them had factory headliner and the same tires? :unsure:
To me the vast majority of annoying noise in a stock Wrangler comes from wind noise, not sure how you can improve that since it's still the same brick on wheels.

Here's the complete list of new changes for 2024 for others to reference. I noticed a big difference in comfort / noise reduction overall compared to my 2018 JL.
  • 12.3 Inch touch screen (w/ wireless Carplay & Android Auto)
  • Dana M220 Full Float axle
  • 5,000 lbs tow rating
  • AMPs dash mount (30x38mm standardized)
  • Warn winch which has wrangler specific harness and lower/neatest fitment ive seen.
  • 12-way powered Driver and Passenger seats
    • Friends with previous 392's also say it's more comfortable in general.
  • Side curtain airbags for 1st and 2nd row
  • Side impact structural improvements
  • Noise, Vibration and Harshness (NVH)
    • Windshield header foam surrounding entire windshield
    • Laminate side door glass
    • new Carpet dampening from factory now
    • 2-5 db performance improvement
    • 7 Mic array, 15db improvement in clarity wireless calls
  • New grill, better engine cooling/fitment with winch.
  • Antenna in windshield
As per the Chief Vehicle Engineer for Wrangler and Senior VP:


I personally notice a big difference in interior cab sound insulation compared to my 2018 JL. It's my favorite vehicle I've owned so far for sure.

Tow capacity on the 392 is still 3500 even with the full float based on everything I’ve read. Don’t have a 24 but would be curious what the manual says. I’ve see two versions…one has all 4 doors still at 3500 and the other had the 392 still with 3500 with others at 5000.

At the risk of going off-topic, and while I see plenty of car websites talking about a new 5000 towing capacity, I've yet to find any documentation from the manufacturer that states 5000 for any MY2024. It seems to be a myth being repeated that the towing capacity had increased to 5000 based on the full floating rear axle. The manual page 190 for the 2024 Wrangler still states 2000 for the 2-door and 3500 for the 4-door, including the 392:

MY2024 Wrangler towing capacities.jpg


I know Stellantis started that myth of the 5000, or at least I heard it from the lips of a Stellantis Rep in a Youtube video, yet in hindsight his chosen words were enticing but not conclusive. Maybe Stellantis is backing off until they feel confident enough to stand by it and not get into trouble by it.

  • The 12,3" touch screen's is cool, but the cameras and other software is still designed to fit the UConnect 8.4 inch screen so even in the extra wide screen the image you get is still the 8.4" view with a filler area added to the left side, kinda a missed opportunity by Jeep to not take advantage of all the area on that new display. Also you loose the round vent that blow hot air right on your hand on a cold winter's morning :)
  • Unfortunately the 2024 392 doesn't have Dana M220 full float axels so the tow rating is not 5,000 lbs, its 3,500 lbs.
  • The AMP's dash mount.... mehhh. I have the 67 design rail which has more flexibility and options and is very well Made in Texas.
  • The Warn winch from the factory is nice but you could add a winch yourself and go with the better built and more appropriately sized Warn Zeon Platinum 10s or 12s.
  • Power driver seat are also nice, but correct me if I am wrong there is no memory function on the 2024? If that is the case defiantly a missed opportunity to add a very useful feature for 2 different drivers. Also I'm not sure my twin ARB compressor will fit under the pax seat now, which kinda a bummer. Also my EPIC Kraken Air-Inflation System won't work with the new seats. I think I would take the old manual seat. If it had seat driver position memory then that would be a no brainer. I also don't care for the red leather seat. I like redheads and red Jeeps, but not red leather seats.... weird?!?
  • The side curtain airbags are a huge improvement. Side impact improvements.... hmmm.... I don't know about that one... I'll let them crash it at IIHS first and then see if it makes any real difference.
  • NVH: Filling the windshield with great stuff spray foam is a great idea. Most of the wind noise is coming from there so every bit helps. Now laminate side windows I am not a fan of, if you end up in the water while off-roading then your not going to be a fan of them either. You can't brake laminate side windows so there is a good chance your going to drown. Now that it's a very slim possibility that you'll submerge your Jeep, but I keep a vehicle escape tool in my glove box for that possibility. The carpet is an interesting way to dampen the sound. 2-5db is a huge improvement, decibels are logarithmic so 2-5 dB is defiantly noticeable. I'll have to test drive a 2024 to hear it for myself. Good on them, and the new 7 mic array sounds like a big improvement over the two mic array in my 392. I think the NVH has defiantly improved.
  • The new grill looks cool. I liked it so much I ordered one painted to match my red '22 Jeep. I think it's more of a branding thing than a airflow thing, but either way it looks cool IMHO.
  • Antenna in the windshield is dumb. Jeep windshields break a lot, it's basically a glass flyswatter cruising down the freeway. A replacement 2024 392 OEM windshield is $2270. A replacement 2022 392 OEM windshield is $810. I'll keep the little antenna on the side.
I defiantly think a 2024 392 is a big improvement from a 2018 JL and it's a hell of a Jeep. The sound proofing on the 2024 sounds like it is a definite improvement. The airbags is an excellent addition. The grill looks cool, so I am jealous and adding one to my 2022. The other stuff is a mixed bag, some I like, some I think is dumb like the red seats and the windshield antenna. In the end its a JL with a BGE (Big Gas Engine) under the hood, and its fun, enjoy.

But every window sticker I've seen says they have them. An example of 2024 Rubicon 4-door:


and the 2024 Rubicon 392:


That's why it's puzzling that this axle was used as the basis for saying 5000 yet they don't document the 5000 anywhere.

Then, too, the 2-door also has this axle but nobody is saying its towing capacity increased above 2000:


So, something else has gotta be driving this issue in addition to the presence or absence of the full-floating rear axle.

My sticker does list the "Dana M220 Wide Full-Floating Rear Axle" and I have a feeling if I look under the 24' 392 in my garage I'll see it there however I can confirm in my manual it shows 3,500#'s.

Yes, I agree there's definitely a discrepancy between whats said by the engineer @ 3:40 in the video and, to @SunsetHill's point, my owners manual still showing 3,500#'s.

2024 with 2300 miles on and I don't hear any rattles. Is it quieter maybe, but it's a Jeep and still has a thin top. It is noisier then my Sierra for sure but I don't hate it. I do get a little wind noise sounds like it's coming from between the front panels of the hard top.

Thank you for replying to my post!
I know that you are supposed to hear the roar of the magnificent 392. I don't mind hearing that.

I am talking about just a marked improvement in rattles and cabin quietness.

My 2023 isn't terrible, but there are a couple of annoying rattles. I know, being picky, but I really want the new screen, and if the interior is night an day difference on the sound, that would give me more reason to upgrade.

I appreciate all the thoughts.

2023 392 not with SOT (thought it would be noisy) and with factory insulation. The factory insulation is impressive. Surprisingly quiet, no rattles at all. We added insulation to our 15 Wrangler Willys hardtop. Made a difference with noise, heat and cold condensation.

Hey all,

Just curious if anybody had went from a 2021,22,23 392 to a 2024 392 and noticed a significant reduction in interior noise?

I mean is it like "Wow, this is so much better"?

I know Jeeps will always have annoying rattles, but is the 2024 way better?

Thank you!

Hello.
I am driving 2024 392 with hard top. You can feel the echo in the cabin when accelrate but i enjoy that. The sound/throttle makes you happier @ the end.
Thankyou.

I did notice that echo, just like in my 18' JL but its louder ofcourse with the 392 but it sounds damn good.

Would be interesting to see if we slipped a mat or something under the removable lid in the cargo area.

I believe Vehicle weight and dimensions also play a part in this, not just the axle. Hence the 2 door and 392 being less then the others.

Here’s a screenshot of the .pdf that has 5k for some models but not the 392

My '24 does feel quite a bit more refined and updated compared to my '23. The '23 feels more raw (not a bad thing). The Sky One Touch is an excellent feature on the '24 which I have, whereas I don't have on the '23 (I have freedom top on that one). I did hear the rain moreso with the Sky One Touch roof as I was driving yesterday. When it is sunny and clear, I don't hear much. I do open the Sky One Touch at every chance since I enjoy and appreciate it. No regrets. I like both. I also understand that the factory Warn winch may not be as capable as some aftermarket solutions, however, I am in full support of what comes from the factory. Attached both original Monroney stickers from the '23 and '24...

Where did you get color matched 2024 grill? I'd love to add one to my '22 as well :)
 
No rattles and overall super plush inside and calls are very clear now.
