I've had this truck about a year now & notice a "wind/road" noise which appears to be coming from the rear passenger side. Has anyone lese experience this noise or is it just me? Any suggestions on "fixes"?

I have a wind noise in my 18 Crew cab.  I believe it be from the shark fin antenna, wiggles a bit when I shake it.   I can't pinpoint to an exact location, seems to be coming  from in front of me.  Need to pull the headliner down and see if tightening the antenna fixes the noise.

My trucks super quiet at all speeds. Do you have any aftermarket items on the body? Even vent visors can make noise.

Nope. All is standard equipment, even the tires are the original Goodyear's. It does have the factory side steps. It has the factory MAX tow package with the towing mirrors, no sunroof. Truck only has 35k on it. Not coming from the shark fin. My hearing isn't the same as when I was young but does sound like it's coming from the passenger side rear. Could be from the front door but I don't think so. I know there's a factory "pressure vent" on the back wall behind the back seats.

Look's good - Check your door seals or door adjustment . dealer replace one of my door seals. Good Luck

I have a 2015 crew cab with the factory RV tow mirrors (the same ones that you have). I have wind noise that comes from the mirrors. It sounds like a loud whistle. It only occurs when the wind hits the truck at the right angle. I have gotten it on both sides of the truck and luckily its infrequent.

Thanks for the reply SgtThor....I have been working on the seals but nothing that I've done seems to help. I have adjusted the door lock anchor as much as it will go in toward the cabs, both front & rear. I've tried adding some of the "3/8" foam" crack fillers in the inside of the door seals but have not been successful to get it but in more than about half around the back door. May look for some rubber tubing that will fit that I can pull thru. My CPO warranty is up the end of Feb & since I have messed with it, don't think the dealer will do anything, so won't pursue that, but thanks for the suggestion.

I have a 2017 Sierra RCSB.

 

A few weeks ago, I noticed loud wind noise - especially in a cross wind.

 

I did some checking and found that a piece of white plastic - attached vertically to the driver side at the rear of the cab - had come loose. There is on on each side.

 

The plastic was loose at the top and had curled enough – I thought – to make the noise

 

I was still under warranty. I took it to the dealer, they drove the truck at highway speeds but could not hear the noise. I got them to glue the strip back on anyway since it was an obvious defect.

 

The noise went away.

Tim...Thanks for the reply. Can you help me a bit more on the location of the plastic? Is this on the out side of the truck? I see something located between the bed front & Cab, not sure what they are.

The plastic strips I found are located at the outside rear of the cab between the bed and cab.

This would be my first choice before trying a DIY.  I was wondering if your truck still had some original warranty left but definitely take advantage of your CPO warranty.   Water leaks and air leaks often originate in different places than they appear.  Your dealer may have a good idea of the likely problem spots on your make and model of truck and have the parts to do a factory fix.   IMO, your truck is too new and nice to be adding foam sealer from a hardware store to areas you think may be a problem.

Have you tried folding the mirrors in just to see if it goes away?

Thanks for the reply. No I have not but what I hear is more road noise than wind. I probably should of clarified that better. Sounds like coming from rear passengers side

How is the tread on the tire on the right rear?  Is it cupped?  Is the tread worn evenly? Not necessarily worn on one side or another, but is it smooth across the tread or feel kinda “jagged” if you rub your hand across the tread?  Point being, poor tread wear can cause road noise.  Maybe rotate the tires front to back and see if you notice a difference where the noise is coming from.

Tread wear is nice, smooth & even on all tires. The road noise is entering either from the door seals or other areas of cab, whether it's from poor sound insulation or some place that needs some sound insulation.. I may have to remove the rear seat on passengers side to investigate further

    • www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.
    • Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.         
    • I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far. 
    • I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install. 
    • Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
