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.

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

    • Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.

    • Looking for this part for my truck. They don't sell just that one piece and to get it you have to pay over $100 even used for the whole air tube. The piece the hose clamp snaps into that is held on by the screw and nut. If anyone has access to one please let me know.
