Silverado 1500 Low speed clunking noise

[Chris Christensen]

2021 Silverado 1500 RST diesel w/ less than 7k miles. I get a dull, irregular clunking noise when going over bumps or rough road at low speed ie. maneuvering in a parking lot. My son had a similar issue that his dealer corrected, in his words, by "replacing plastic leaf spring bushings with rubber bushings". My dealer has no TSB reference or replacement part numbers that would apply. They replaced bushings and retorqued leaf springs but that did not correct the problem. Has anyone dealt with a similar problem?

Try the “spring things”. Had same issue, went crazy looking. Sound is likely leaf springs

It's just typical GM leaf springs. Every truck since my 98 has done it. Homemade fix, but bicycle tubes, cut them in like 6" lengths and spread the springs apart to slip them between. Acts like a rubber insulator and I only had to replace them every 3-4 years. Haven't done it to the new truck yet but I'm sure I will in the summer.

Thank you sir, but seems like there should be an actual GM fix. Drove an '09 Sierra 2500HD for over 10 years and never had the problem. Maybe it's just the 1500's?

Could be just the 1500s. I don’t care if gm fixes it or not. Still enjoy the trucks and I don’t mind my fix.

This is more of a 1500 problem.

I have the same clunking noise in the front end of my 2022 Silverado 1500 limited (LTD) (refreshed) rst duramax. I installed a leveling kit the first week I had it. I thought that was the problem so I retorqued it. Still same problem. The noise is getting worse. Anyone have a solution or advice?

Was there supposed to be some text after the quote?

same problem with my 2023 RST Duramax, 500 miles.  Just returned from service (4 hrs) obviously not corrected.

[IrishIowan]

I saw the email address above and I thought I would attempt to get some resolution on my specific truck.

 

VIN number included in email i sent to GM.

 

I had the clunk noise coming from the rear of my truck when going over small bumps such as turning into my driveway.

 

I took the vehicle to Karl Chevrolet in Ankeny, Iowa.  I told the service advisor there was a Technical Service Bulletin (21-200) on the rear leaf springs.  The service technician diagnosis was the rear shocks were bad (did not rebound correctly, and were different lengths when extended).  The dealership replaced the rear shocks.  Noise was still present.  I understand the TSB had a correction date and applies to 2019 and 2020 trucks, but the condition was present on my 2022.

 

I setup another service appointment for the same reason, but also reported my rear slider window was leaking and the air conditioner was not cooling.  Service technician diagnosis was rear window has a crack (known issue), the air conditioner had a leak.  The rear clunk was diagnosed as rear axles had too much play.  Rear window was replaced under warranty.  Air Conditioner condenser was replaced under warranty.  Rear axles were replaced under warranty.  Noise was still present.

 

I answered a dealer survey and thanked the dealer for service on the rear window, condenser and axle replacement but I also told the dealer the noise was still present and I was not satisfied with their solution to stop the clunk noise.

 

By this point the truck had been to the dealership twice for the same problem.  Parts may have been replaced that were not defective and replaced parts did NOT fix the clunk noise.

 

I purchased some of the Spring Thingshttps://www.spring-things.com/?msclkid=440fd99d91fb1b19cd63bc184cbc06b0 from the internet, watched the install video on YouTube and installed the items in less than 10 minutes at a cost of $45.  This simple solution fixed the clunk noise and my truck has driven and sounded like when it was new.

 

While this clunk noise may seem minor compared to major issues like engine, transmission or electronic issues the clunk was to the point it was driving me crazy like a wind noise you can’t resolve.  I contemplated selling my truck and purchasing another brand of truck.

I have done things like this on previous vehicles that the dealer couldn't seem to find the problem like a squeak, rattle etc and I have found the issue myself but when I did fix the issue I always called the service mechanic manager and inform him of the fix I found to be the problem that way they know what it was and maybe helped someone else, they always thanked me for the issue fix and will take note of it.
