I purchased a new 2017 Silverado this past March. After about 3000-4000 miles I started to hear this clunking/ popping noise in the rear of the truck. I took it to my local dealer twice and they said they lubed the leaf springs. Didn't fix anything. I then took it to another local dealer who said the noise is coming from a leaf spring schackle and they think they got rid of the noise. I drove it for a few weeks and didn't hear the noise once. Right around the 3 week mark I started to hear it again so I took it back to the dealer. This time they said they lubed the leaf springs but this is only a temporary fix. I was understandably upset considering this is a brand new truck and it should not be having this issue. I did some research on this and found that some people had the springs/schackles replaced and it corrected the problem. The dealership said they will not replace anything until a permanent fix has been sent out by GM. So I called GM to complain. They basically told me the same thing. I am not happy driving around a truck that sounds like it's falling apart in the rear end and GM won't do anything about it. They won't even make the effort to replace the part to make the customer happy. Has anyone had this issue? Any advice on what to do or who to call and complain to get this issue fixed? Any advice is greatly appreciated. Thank you!

I’m gonna try the inner tube trick this weekend

Tubes work, but the key is in how you cut them and where you place them as the leaf springs not only move up/down, but side to side as well. This movement could push them out, but when they stay in it

Just did the rubber trick on my 2019 GMC Canyon and it worked great and simple as well took about 20 minutes. Jacked up the rear of the truck so springs would not be engaged, removed wheels (you could

That appears to be gm’s response to every problem since 2014s rolled out. Just left dealership where they told me I had 4 ball joints out, needed new pads and rotors, and my transmission fluid smelled “burnt”. Went to local shop and said it all looked good. I had just had the brake pads change so I know they are crazy on that one. Will likely get trans fluid changed as I’m at 55k and I’m about to do the tcase and diffs. Sad

Tons of us have had this issue. I used the bicycle inner tube trick to get rid of my issues.

How would I do the bicycle inner tube trick? I assume you cut it up and put pieces in between the leafs springs? Please let me know where I would put the pieces to eliminate this noise. I'll try anything at this point. 

One question though, the dealership said the noise is coming from the rear schackles not the leaf springs themselves.i can't picture how inner tube pieces would help stop the noise in the schackles. Again any info is appreciated. Thanks!!

You are exactly correct. You cut it into strips the width of the spring. Jack the truck up to relieve all pressure on the suspension and then take a pry bar (I wrapped mine in a shop towel) and pull the spring apart ever so slightly and slide it in. Do this for all contact points. It helped mine tremendously. The shackles I am not sure on. I still get a slight thump when I slow down fast on a decline, but it is very rare and I just dont notice it anymore. I went the route of the dealership (I bought certified pre owned) and got the same run around as you are getting. I got frustrated and did the inner tube trick and it has worked out for me. I honestly do not think GM will release a "fix" for this minus packing the springs with so much grease it is ridiculous.

Ok thank you. I will give that a shot. GM claims they are currently working on a fix for this noise but they couldn't give me a time frame so I agree with you that it will never happen. It's too bad because I love this truck but I don't like doing business with a company that knows there is an issue with a part and refuse to fix it no matter how big or small the problem is. Thanks again. Any other info and suggestions are appreciated.

Just like sippisierra said, cut 1 3/4 or 2 inch just measure the width of the spring and I think I cut mine 2 1/2 length wise. Place them in front and the back of the middle spring. While you have it jacked before applying the rubber, clean out all the old grease so dirt and stuff don’t stick to it.

Did you end up trying the innertube? Curious to know if it helped your issue

Yeah I’m pretty much frustrated with GM right now. I have a 16’ Double Cab GMC Sierra, that has already been in the dealership for a malfunctioning cadalyc converter around the 1st of October. Maybe 2-3 weeks later I hear a clunk sound coming from the rear. And last night while driving I heard a sound coming from where the transmission and driveshaft meet I’m assuming.

 

If it wasn’t such a pain in the azz to get a loaner vehicle from my local dealer I wouldn’t be pissed, they constantly give me the run around about how I would be the 16th person in line for a loaner, wtf? 

 

Also so where I live in Huntsville  a small Tx town with bumpy roads, this sound doesn’t keep me assured everything will be okay.

I did end up putting pieces of a tire inner tube between the leafs and as far as I can tell no more noise. Thanks... Still wish GM would fix it properly though.

I have bought two 2017 GMC 1500 Denali's 4x4 and both have the rear end noise everyone has been describing on this thread and the others.    I have a 20 year old truck at my ranch an it is quiet than these new trucks, very annoying.     After about 5k miles is when I started hearing it on both trucks, on one truck dealership tighten leaf springs and that helped for about 30 days.   The dealership keeps telling me its the floating axle in these trucks and that is just the way it is and cant be fixed.     I cant believe GM would want to build a truck with this type of noise in rear end.  

 

Maybe  the only way to get satisfaction is to bring a class action suit  since this cant be right, seems to be a very consistent problem, so likely a lot of us, everyone's getting a different story, etc..    I happen to know some guys that do this type of work and will discuss with them.  Stay tuned.

I have a similar issue. I have a 2017 double cab sierra 1500, which has developed a rubbing noise in the rear driver side. It sounds like metal rubbing against rubber. It can be easily replicated when I push the bumper down by hand with the vehicle stopped. Not sure if this is the same as your issue.

      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.

      Well one of our most reliable vehicles was sold yesterday. The first and only I gave for free to a grandkid. If they got skin in the game they take care of it. My wife bought new. Five years later my daughter got it to use. We got it back and gave it to our grandson after graduation. He did zero maintenance just oil changes. When the AC quit he drove his mother’s car rather than get it fixed. Instead he just bought a beater and sold the Elantra.

      OCI, not when but why?

      By KARNUT · Posted

      I usually do as well or better than the sticker for mileage. Usually better going west than east. North then South. Wind makes a difference. I’m not usually a conspiracy theorist. But it did dawn on me I’m going by the vehicle calculation. Now that would be interesting.
