Took in 2022 LTZ Z71 4WD Crew Cab with 13k miles for rear clunk noise.  Dealer found Rancho shock is defective.  Removed shocks and drove truck and noise was gone.  Checked shocks, one was 1.5 inches shorter than the other and wouldn't fully extend.  Old shocks back on truck, NEW shocks on order should be 7-10 days.  Will post again after new shocks are on truck.

Update:  Shocks replaced and ride is better.  Noise is still present, will be contacting dealer about Technical Service Bulletin 21-200.  Last week Service Manager said they had to replace the bad shocks first, before they could do anything with leaf springs.

Update: Noise still present, still waiting for appointment at dealer.  I suspect something is loose, may not be leaf springs, but need to convince service advisor to have a technician spend some time to try and diagnose.  Two co-workers have the same truck and no noise.

on mine they made a mess of the springs, so they replaced springs and shackles, however a couple of other people i know have had just the shackles replaced and it worked!

I just wash them real good and shoot some silicone spray in between the leafs. Stays quiet for a long time.

 

I've done this on the 2014. 2016, 2018 and now on the 2022.

Update: 22 Silverado Crew Cab LTZ 4WD - truck serviced for continued clunk noise from rear, dealer says rear axles have too much play, specification is .026 inches, one is .028 inches and the other is .029 inches.  Waiting on replacement axles.  I also noticed rear window leak after car wash, dealer will replace sliding rear window under warranty.  Also have Engine Open warning, dealer will replace hood latch mechanism.  Waiting on parts, may be awhile since UAW and GM have a tentative agreement.

Update 11-27-2023 - Dealer replaced rear axles, clunk noise still present.  Rear window replaced, no leaks.  Hood Latch replaced, no alarms.  Truck is still under warranty but I am sick of the dealer service department not being able to fix the clunk.  I purchased Spring Things like so many other people on this and other forums and the clunk noise is gone.   I don't know how long the Spring Things will last but it is so nice to have a quite ride and not have to anticipate the clunk noise everytime i pull in or back out of my driveway.

      2027 GMC Sierra: Official Discussion

      Holy smokes. Clearly not a deal on that truck. I just mean in general, matte or painted trim is becoming more normative than chrome, but I know the Black Optics packages on various vehicles are being sold as uplevel trims. They look really good, but sheesh. It's just paint and plastic.

      I Wouldn't Know Where to Begin    Oh I know where I would begin but I'm just one of over eight billion people on this rock. Eight billion versions of where the goal post is. How large it should be. How far to kick from. What ball is the right ball. Elevation. Age.....are you getting the point? It isn't about disagreeing with one individual. It's about agreeing only with one individual. One's self.   Agreement comes when multiple people hold the same point already. THAT is the goal of an education. Building the Social Contract. That thing that allows us to all read this sentence. We've agreed on the alphabet and how to arrange those letters into words we agree upon whose meanings hold true for everyone entering into that contract. Those words arranged into a sentence form an idea and several sentences strung together in a paragraph convey an argument for or against or inform the reader of a state, condition or perhaps reveal a things nature. Paint a word picture. Make oneself known.    This contract is not limited to words although they are often explained by words. Things like numbers and their usefulness. Physics, Chemistry, Medicine, Music, Art and so on.    The frequency of middle C (C4) is 261.63 Hz is a first principle. We build on that to make music we all can enjoy even if we all can not compose or play. You don't have to master it to make it enjoyable and useful.    So why is the Beginning so difficult? Why is agreement so elusive?   Everyone "Signs" the contract (when receiving that education in obtaining it)  but fewer and fewer in this world have any intention of living by that contract. They find exploiting that contract more advantageous. Disruption. With intent. Without intent. In Ignorance. In your face. With a double dog dare you. With a hold my beer. In resistance to that contract and in spite how it looks on us. It permeates the very air we breath.    In this way the contract is subject to advantage. Abide by it when it serves you, disregard it when it doesn't. Unpredictable and self-serving. Corrosive.....Toxic........   It says a lot about a persons character to disregard the contract, the truth, first principles. None of it good.        ********************************************************   https://medicine.yale.edu/news-article/character-vs-personality-who-we-are-and-who-we-aspire-to-be/   Just an interesting article.

      It costs $5,250 for the Yukon Nightfall option (black wheels, emblems and illuminated black GMC grill badge). What a "deal".

      Android auto could not connect

      I keep getting the above error message on my 25 Sierra.  If I reset the infotainment unit (via the phone hang up button) it will work again for a day or 2.   But I dont want to do have to reset  all the time. Works fine in my 2023 Corvette. On both vehicles I connect wirelessly.   I have a Google Pixel 10 Pro XL, phone is up to date.  Any Ideas.  See attached

      LOL, its thrown a few people because this item is being talked about in the gas part of the HD forum. Probably wouldn't be a bad idea to put a very brief wording in your profile with the year/GM or Chev/2500 or 3500/ and yes the 6.6 Duramax. When I joined this forum I could see the confusion ensuing for my own truck unless I had it listed with my chosen name handle unless one has a few vehicles that apply to a GM forum as that becomes confusing as well. Anyway its all good, makes for a little forum excitement 😉
