I bought a 2019 silverado 1500 in February of 2019, theres right around 5 thousand miles on it.  Recently I have noticed a loud thumping sound in the rear end like a clunk sound when driving down alleys or uneven roads. I hear it when I back out of my driveway or pull into my yard. It sounds like a bowling ball is rolling around in my bed.  Anyways I took it to the dealership where I purchased it. They heard the sound and said there is a protocol that they have to follow.. first they clean the debris out of the leaf springs and grease them up real well. If the sound comes back which I know it will the next step is to replace the leaf springs.. Now from what I'm told and read that probably wont fix the issue either. I'm told it's just a poor design. What am I supposed to do? I'm making a big payment on a brand new truck and it sounds terrible. Why should I or anyone have to deal with this? Help me out someone!! Thanks!!

Welcome!

 

First off, not sure the HD section of the forum is the right spot for a 1500 issue.

 

Second.  Is your truck a NEW body style 2019?  Or an OLD body style 2019, aka "Silverado LD"?

I didn't realise this was the HD forum. But I'm sure theres alot of knowledge on here HD or not someone will have an idea! GM is currently working on a bulletin to repair it. There saying it's the leaf springs making the sound! The answer I'm getting is it's a poor design.. who knows! It's a 2019 new body style 1500

Check the flange on the yoke of the driveshaft.  We have had one truck that the weight on the flange broke and caused a vibration.

I just started having this same problem on my 19 trail boss Silverado. And I wouldn’t drive it I had it towed to dealer I only have 19000kms on it and they told me it’s normal I took videos and documented everything. In mine it feels like something to do with the automatic rear locker.

Hey Ryan my names Nick.  I have a 2019 Silverado I purchased used.  We just heard this same noise last night while backing out of driveway and turning out of neighborhood.  Initially we thought the kids left a ball or something in bed of truck and it was rolling around.  Did the GM dealer you brought it too give you a bulletin number or anything?

I am currently dealing with this issue on my 19 Silverado LD with 13,600 miles on it and it’s been in and out of service for the last three weeks. Leaf springs replaced twice and the rubber bushings installed, still having the issue. Got told by the dealership they won’t keep guessing what the problem is and throwing parts at it and that’s it’s a normal noise and it’s a truck that their all noisy.

I have a 2019 Silverado LT Trail Boss - about 24K miles and hearing similar sounds; only at low speeds, in and out of driveway, etc.  Haven't taken it to dealer for this sound yet, but checking suspension components and mine seems to be the spare tire making the noise.  When under the truck and pushing up on the spare tire, hearing similar/same noise...

I experienced the same noise. Had it in and out of the dealership several times. Picked it up today with a spacer inserted into the back of the leaf springs. See photo. Dealer says that this eliminated the noise. Chevy says that it's a known problem with the Colorado. I have a Silverado 1500 - 2018.

I know this is an old thread, but my 2019 does the same thing. I had a 2017 that was doing the same thing, and actually fixed it before it was totaled out. What is happening is the leaf springs are shifting from left to right and causing the noises. My 2017 did not have the little brackets with rubber on them on the end of the lower spring, but my 2019 did, so I figured that it would not be an issue...but it is.

 

My fix was that I put two long U-bolts on both sides of the axle on the leaf springs. I didn't put a whole lot of tension on the bolts, just enough so that they wouldn't back out and still allow them to flex. This completely eliminated the problem and it was a pretty simple fix. I wish I had a picture to show but I guess I never took one.

 

So, if you are really wanting to get rid of the clunk, it is a fairly simple $30 fix. Might have to do it on my 2019 now also.

I had the same issue on my 2019 LD. This "repair" is what my dealer did and it fixed mine. No clunk now. I am concerned they seem to have removed the rear spring clip. Otherwise I'm happy.

      MPG at 600 miles

      By Chuck FB · Posted

      There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65

      Factory front brake rotors...defect?

      By Chris80s · Posted

      On my wife's 2020 Blazer (~69000 miles), we started to notice the brakes pulsating at faster speeds. Typically around town you don't notice anything, but highway/interstate driving you will notice it. I decided to pull of the front tires and look at the brakes. I figured with the milage, the pads should be wearing out to their life span, but they actually looked decent. Still with "meat" on them. One pad has a ridge wearing in it, and that same rotor is showing the ridge too. That's not the concerning part...the other rotor appears to have a raised bump on it!  The picture make it look like a pimple! Very odd and strange! NOTE: These are the factory brakes and rotors.   I'm attaching pictures of the front brakes and what they look like ate ~69000 miles.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      2024 Chevrolet 2500 HD Custom 6.6 Gas Canadian built Truck  I tried to search for my previous thread on this topic but cant find it so my apoligies  for starting another one    #1   Since we have owned our truck purchased new it has this strange noise after using the remote start function  you press the remote start and you hear it start but right at the end of it starting it almost seems like it wants to start again after the truck is running .   There is no gap in time it is right at the end of the start . Almost sounds like when you have started a car/truck and its running and then you try and start it again and you get that grinding noise ,sort of     #2  You can only hear this if you are standing outside of the truck and near the truck  you cant hear it when you start the truck from inside  the cab . So it may very well be happening when starting the truck that way as in normally    #3   This only happens when it is started after sitting . For how long I don't know but it happens after sitting overnight for sure and it wont do it if you stop the engine after starting and then start it again  I have had it in to the Dealership before concerning this but they did not have the truck  when it was cold to hear it . Now its back in the Dealership left it overnight so they could possibly hear the problem . They said they tried and nothing happened . Well they did not know what they were listening for . I started the truck remotely and BINGO it makes the noise . Oh that sounds weird they say . We need to look into it ! I have left for this week at the Dealership    Does your 2024 2500 HD gas do this ?  Any of you fellas care to take the time and trouble to film this operation from a cold start  so I can hear what your sound like  Really  would like to know if this is anormal sound  Thank You Fellas !!

      2026 Z71 Forward and Rear Park Assist help

      By Slow · Posted

      2026 Z71.  The other day I was backing a trailer into the barn.  The alarm was going off just because the trailer was in the field of the warning sensors when you get too close to something.  For some reason now the warning alarm doesn't work anymore.  It used to go off when I was just normally backing my truck into garage.  I still have the guidelines in the back up camera.  Is there a button or something to push to turn the sound/Alarm on and off?  I have the touch screen in this truck.  There isn't a "P" on the dash except for the parking brake.  I can't find anything in the touch screen under settings or vehicle.  Thank you in advance.
