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"?

Posted (edited)

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

    • Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol    
    • You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !
    • This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.  
    • My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page
