I'm also starting to experience this problem with my 2016 Silverado. My question is I have lowering shackles in the rear and I'm hesitant to take it to the dealer for the clunking because I feel like they'll blame the shackles.

Worth a shot but to be honest, if they do decide to do warranty work you will have them greased (it won't fix it long term), then have them replaced (again not a long term), and then get fed up and do the rubber like everyone else has had to do. It makes me angry GM cannot admit the problem and get a fix out, either some better springs or a rubber not plastic silencer.

It is in the springs, but replacing the springs won't fix it, it will come back. The rubber pads in between the springs need to be lubricated with grease on the top and bottom of the pad. This will fi

Brought mine into the dealership last month for this problem twice. First time they tightened everything down in the rear end, took them an hour to do so. Then right when I got back into the truck and

I'm waiting on the pictures of the rubber installed so I can give that a shot.

I will take some pics this evening if I get around to doing it. If I do not then I will upload some pics Saturday. This better fix it. I am going to blow a gasket soon I am telling you, I had a 2002 Z71 200,000+ miles and the leaf springs never made a sound.

1. Get you some bicycle inner tube or rubber sheet (HD sells in plumbing dept)

2. Raise truck from frame on driver side just in front of rear wheel.

3. Use jack stand for safety

4. Use large flat blade screwdriver or pry bar to separate leaves at front of spring

5. Insert rubber piece then remove pry tool. keep your digits out of harm's way

6. Repeat 4 & 5 at rear of spring

7. Repeat 2-6 on passenger side

Just did this this morning and when I shake the bed side to side the only noise I hear now is a little axle play; spring clunk is gone. We'll see how long it lasts. Fluid film was getting me about a month before the noise returned.

I was just headed to these forums to write up the same complaint. 2017 GMC Sierra Elevation and it pops SO loud every time I backup with the steering wheel turned. I originally thought it was a front end problem but it's definitely coming from the rear. Wasn't sure if it was the rear end lock engaging but I have to hear it at least 3 times a day in the areas I park. 3 times a day I get frustrated and discouraged with a truck that has only 3000 miles on it. Probably headed to the dealer but it doesn't sound like I'll be getting much help there until a service bulletin of some sort is released. Thanks for posting.

Just wanted to give an update. I did the rubber fix for mine this weekend, it worked. I used Goodyear bicycle inner tube. I will say it made me chuckle as I was underneath the truck sliding it in and read the big MADE IN MEXICO stamp on my spring and then the MADE IN USA on my inner tube. I would upload photos but it looks exactly as above and followed the same procedure as paumat.

I had the same problem on my 2015.  Went to the dealer and the confirmed it was the spring noise, but would not fix repair under warranty because I had a leveling kit installed.  Made me chuckle-truck has 30,000 miles and sounds terrible when turning or going over bumps-especially if towing a trailer.  I tried greasing the springs and that didn't work.  I added the bicycle inner tubes, and that helped, but I still had some noise(I was probably paying more attention to it than I should have been though).  I decided to replace the springs and saw recommendations for Deaver Springs in Santa Ana, CA.  I made the leap and purchased them.  Took 4 weeks to make and a week to ship to me in Florida.  The install was much more of a challenge than I had anticipated-you have to remove the hitch to get the rear shackle bolts out which wasn't bad, but to replace the drivers side spring you have to drop the fuel tank.  

Very pleased with the ride of the springs, and finally no noise.  The Deavers are expensive-$900 and I can't tell you if they are any better than the multi leaf springs you can buy elsewhere.  I ordered mine with a 3" lift as I am running Fox Coil overs in the front.  I initially didn't install with the factory blocks, but that made it sit level and I like a bit of a rake so I ended up adding the blocks back.  Note that the top plate that holds the U bolts doesn't come with the new springs so you have to remove it from your factory springs and install on the Deavers.  Hope this helps anyone considering replacing their springs.

This happened to my 2017 Z71. Actually started making the clunking noise when I got it back from the dealership. They were replacing the headliner because of a rear window leak and had my truck during the holidays. It was so bad I thought someone took it on a joyride and thrashed it. Here’s a pic of their write up, hope it helps.

 

 

 

FYI the springs still sounds creaky like an old truck but according to this forum it’s something that happens when it’s below freezing. So I’ll wait until it warms up before complaining

Thickness I honestly couldn’t tell you. I used (most do) bicycle inner tube. I bought the Goodyear off road bike tire innertube and cut it down to be the thickness of the spring.

GM makes a special lubricant just for this problem. I’ve used it and it does work . I’m not home now to look up the name, but the parts guy should be able to get it . Did mine several months ago and it’s still ok.

I have the same issue on my 2016 HC. Would hear clunking in the back whenever I would back into my driveway. Asked the dealer to look at it when it was in for service and they said there was a service bulletin about it and 'they tightened things up'. Problem reappeared a few days after and they have ordered new springs for me. Parts are back ordered but all covered under warranty.

Going through this on my new to me 15 Silverado. I'll have to investigate the springs.

      Aftermath of Repair of Leaking Brake Line

      By unit731 · Posted

      Thanks for response. Leak was right under drivers seat or thereabout.   Had checked by other mechanics and have read other information.   The solution can be a tad complicated and replacing multiple parts And with some.  The issue was still the same.   The brakes do work.   Just that the pedal is softer and goes further down.  But the brakes do work.

      Breaking News!    I'm going to tell you that I'm going to tell you.  Then I'm going to tell you what I'm going to tell you.  Then I'm going to tell you.  Then I'm going to tell you what I told  you.  Then I'm going to tell you what I'm about to tell you on the other side of the break.  Then we're going to break. Then I'm not going to tell you what I told you I was going to tell you.  But I'll tell you something else that is Breaking News just coming to the desk that everyone reported on yesterday.  Then I'll tease a human interest telling I'll get to on the other side of a larger break. Then I'll tell you one item in 20 seconds and go back to an even longer break. Longest break of the night.  Then I'll tell you a fluff piece that takes 10 seconds and sign off into a three minute break while you wait for the next 30 minutes of rinse and repeat on the local news.    In al you'll get about 12 minutes of something, 5 minutes of which is worth hearing in a 30 minute show and 18 minutes of advertising at a sound level twice as loud as the news.    Of course you can switch to cable news and hear 12 different people tell the same four stories in much the same format as the Network News for 20 hours of which the majority will be advertising.  And four hours of late night Specials about things you wonder why you stayed up to listen to. Half of which will be repeats.....   OR you can go for a drive

      Audio Dampening and quiet

      By Afennell19 · Posted

      Did you ever figure this out? My 2022 Trail Boss, and now my 2026 LT did this from time to time.  I believe it was more connected to Android Auto and my phone being the cause. Maybe try going for a drive, sans cell phone.... and see if it happens?

      2026 Sierra 1500 Denali - Sound upgrade?

      By Afennell19 · Posted

      I have a 2026 Silverado LT, the non bose as well.  Upgrading the door speakers is pretty straightforward. You could honestly go to walmart, or Auto Zone/ O Reilly and get a set of 6x9s for the front, and 6.5s for the rear. You do also have to get some adapters for each, but they are like $10 a pair on Amazon. Then some plug and play harnesses that are about $10 a pair on Amazon as well.  And I would also suggest a 10 pack of the Amazon Basics sound deadening. Slap that all around the speakers and on the open metal of the inside of the door. And your golden.   I am currently doing this with my Silverado. Although I am having a bit of trouble because I am snooby I guess and bought some Alpine S2 S69c's which are 2 way components and I am having to wire from the door up to the dash....  Having never installed speakers before, its taking me just a bit to get everything correct. But if you dont buy expensive component speakers, and just some $40-$50 door speakers. You will DRASTICALLY improve the sound over these stock paper cone junk speakers. I thought my Silverado had an issue with the radio/ sound for a while.  Come to find out.  The stock speakers are just THAT SH*TTY   I cannot wait to have some decent sound in the truck   What did you end up doing?

      Parking Brake - Automatic Engagement Questions

      By newdude · Posted

      Its all automatic based on yaw sensor data.  If enough incline is detected, it engages.   My recommendation though would be to disengage it before driving off and not let it auto disengage by touching the gas pedal.  The HD trucks use the same setup as prior years, the drum in hat park brake.  But now with an electric actuator.  If you drive off repeatedly over time, it can torque the park brake shoes and can also prematurely wear them out.           Electric console shift will set the park brake on flat ground too.  Pretty sure they've got it programmed to activate every time.
