Road noise- interior

[HKP7PSP]

Now this is a theoretical observation but there are some videos demonstrating how stiffer the DT frame is over the DS and what they point out is that the DT has far less flex. When it was driven over some alternating bumps the bed and cab seemed to not move opposite each other at all whereas on the DS, you could easily see the two parts moving independently.
That tells me that this polishing action would be far less on a DT - but is still an area of concern for me.

Very good points. I was able to order the part for $11.xx plus shipping, which means FCA probably spends at most a buck or two to make / procure them - so why did they delete it halfway through the model year? There has to be some kind of reasoning for this.

That is a good point, however there will still be slight vibration differences due to the cab and bed frame supports being relatively soft to absorb and not transfer frame vibrations.

I didn't intend to freak anyone out. There was a design intent behind having the seal in 4th gen and early 5th gens and would be hard to believe they just cost cut it out. Just FYI that if you've added the seal or are going to add the seal you may want to consider some additional protection of the paint.

My truck seems pretty noisy up towards the rear of the pano sunroof. I downloaded a free decibel app (not sure how accurate it is, I may try another one to compare) and I have about 65 DB around town and 75 DB on the highway at 70mph. Anyone else try this and what are your readings?

How much of a difference is between 58DB and 75DB?

A lot...

I don't know if it is my imagination or not, but I think my road noise level in the truck is louder when the audio system is playing music from any source. When I lower the volume level, the truck suddenly sounds quieter - less road noise.

I'm just wondering if the active noise cancellation system is misbehaving?

Like others have stated. My road noise level is louder at different times. Not consistent. Could the rear vents be sticking open at some times?

I have similar faint noise coming from the rear seat area. It sounds like wind noise or like a white noise. I think it’s coming fro the noise canceling system. I need to do some more testing to see for sure.

I don’t have the off road package or sunroof, and stock tires on 20s.

I had a friend drive while I rode in the back seat with the seat back pulled down..... I think it's the uninsulated back wall of the cab and the air vents causing the White Noise you're talking about

I put the seal in last weekend and I think it made a difference. I don't here the outside as clear as I did before. I feel without the seal the vents in the first photo are pushed open by the air moving between the box and the cab, It seemed like something was open behind the back seat. I didn't need the blind spot indicator in the mirror I could hear the car in my blind spot and the rear tires humming down the road. With the seal in place I don't hear it anymore. I was able to put the truck in off road 2 and crawl under and stick it on. The clip above the 33 gallon tank was the only hard one. I still have some noise and there is a sound pad behind the seat (that my truck was suppose to have but doesn't) I think will take car of the rest of it. Hope this helps, I will post photos of the sound pad behind the rear seat when I get to doing it.

Is that road salt in your pics?

Has anyone changed out the OEM tires and went with a Michelin which is known for being quiet. I swapped out the cheap Goodyears on my Patriot and put new Michelins on it was night and day difference. Also, is the road noise more heard on the 22inch tires or 20's ? I have the 22" which are low pro.

Definitely more road noise with the low profile tires especially of the slap slap slap type sounds... A 275 50 22 tire is available which would give you slightly more sidewall to minimize tar strip and Road seam slapping noises

I have a Rebel and switched out 18" OEM wheels for Fuel Hardline 18" but kept the original 33" Goodyear Wrangler Duratrac and I rarely notice tire noise with them. My truck is a July build and is very quiet inside. It does have the horizontal cab/box gap noise seal from factory that some members don't have. Only issue I have with entire truck at 3,000 miles is squeaky console when passenger rests arm on it. Not a big deal until time for other service needed .

I complain to my dealer about the squeaky armrest he said they had seen it before and would order a replacement

May not be what you're hearing, but different road surfaces will sound more or less loud. Around here, the concrete road surfaces are much louder than asphalt.

Yes it was road salt.

Hi The_Chemist,

We can't necessarily give any technical feedback however, if you end up going into the dealer for an official inspection, don't hesitate to reach out. As you know, our team is available via direct message and would be happy to help.

I do get some road noise....what about "creaks" coming from ontop of center stack above radio the black plastic. I have real problem with that going over small bumps in the road very annoying...

If you can isolate where it's coming from try some Dupont dry spray lubricant..... I had an annoying squeak in the console and fixed it with the dry lubricant

 

[Fidomac]

Yes it was road salt.

I need to be more careful about washing between the bed and cab...

I posted this before, but if you really want to kill road noise from the back wall, hanging 1 piece of Mass Loaded Vinyl (MLV) the size of the wall will knock it down by about 20-40%. You'll want one large continuous piece and for best results hanging somewhat loose. It's actually pretty easy to do on the Ram. Just cut to size, then cut a couple slits where the seat belt hooks are. Cut a couple more from the retaining clips. Then hang it on and fit the rear liner back on.

I've played around with a number of different products to try to reduce interior noise, and MLV is by far the most effective to diffuse/absorb that road and wind frequencies.

Lots of info online about it. My personal unscientific trials consisted of running a white noise generator on my phone. Then covering it with various materials. Open cell foam did nothing. Closed cell foam did very little. Blankets very little. Butyl rubber damping material (dynamat) did very little (it does other things though). MLV.... Almost eliminated it. It's not super cheap and it's heavy, but it works.

In my last truck I lined almost the entire thing including door panels with Dynamat, Closed cell foam, and MLV. The truck was almost dead silent at under 35 mph. Then you go up against the window noise and nothing you can do. Only problem though was then you heard every other squeak and tick. And your kids..... Lol.

I should have been more specific. What I actually meant to say is that on the same road, my noise level can vary from time to time. It always sounds to me like it is coming from the rear of the truck. That's why I suspect the vents may be the culprit.

The concrete roads here in PA are really loud as well. Black roads are fairly quiet. My Falken A/T tires may be adding some extra road buzz as well.

The trucks that I test drove, both air suspension and non-air suspension without the off road group (all season tires) were really quiet.

The wildpeaks are pretty good noise wise but definitely more buzz than A/S. Throw some Michelin defenders on and then it'll be really quiet but look like a sissy truck.

I really do like the Wildpeaks. Traction with them on wet roads or ice is really good. I get no fishtailing whatsoever.

I'm very happy with mine as well. I maybe would like a touch wider size, but then I'd have a ride that may be a bit stiffer (different rating). Grip on snow is great.

A good compromise are Michelin ATs. I had them on my 2016 F150 FX4 and they were phenomenal. Truck came with crappy Goodyear’s that the dealer could never balance right so they swapped me to those to shut me up. Still 40-50% tread left after 50k miles too.
