Only when going over large bumps like speed bumps and pulling in the driveway 

Did you have a trailer hitch in? I thought mine was making noise till I realized that was the bugger making noise.

I have a 2020 and from day one I thought my spare tire was loose. Uneven terrain, taking a speed bump at an angle and especially backing out of an uneven driveway the clunking is worse and loud.  

 

From digging around here and on other sites I found my issue was the leaf springs are slapping against one another in the spring pack, especially when they are being twisted. Dealers have packed the springs with grease which will work for awhile and once it gets dry the sound comes back. A member here had a how to to add heavy duty rubber as isolators between the springs.  I added the extra rubber between leafs and it did help muffle the sound but really never went away.  

 

You get used to it once you realize there's not much you can do and it isn't doing anything bad.  Loading the truck with weight will also make the sound go away.  I usually do 200 lbs in the winter for traction and the extra weight doesn't allow the leafs to slap against one anther when they are being twisted.  I also just installed a set of Airlift airbags and that has also really tightened up my rear end even when theres no load.  Really improved the ride and quieted up the clunking to the point its basically gone. Still need to drive the truck more but the few test drives I did are like night and day.

Old thread but my 2022 Silverado 3500 is doing this exact thing at 33k. Just started to do it a couple of months ago. Couldn't get it to do it for the dealer unfortunately but its definitely happening after coming to a dead stop and then taking off again. My old 4tunner did this bad and was fixed by greasing the slip yoke and u-joints. I can't find a single grease zero fitting under this 3500 however so I'm at a loss on how to grease things up...

 

Any of you guys that had this problem a couple of years ago find a solution?

Could it be the hill start assist holding your brakes? You said it's worse on an incline. I notice my 2021 definitely does it as well, I was thinking either the hill start assist is engaging without it showing on the dash or possibly a slip yolk issue (from recent experience) I'm new here and just spitballing.

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.

      He is not saying that an SAE *W20 will have more viscosity than a *W40 due to MORE VII polymers. He is saying that although multiple *W40 may post in the PDS the same or similar 100 C and 150 C viscosities that the blenders choice of modifier TYPE and AMOUNT to get his chosen base to grade will not give identical real world viscosities in shear and at temperature. All will pass the SII test but not all will pass the 100 C HTHS (unpublished value) testing the blender does and relies on to get the required by law "percentage improvement' referenced to his last great work.    Tis the problem with the lie. Once told others are required to support it.

      Parking Brake - Automatic Engagement Questions

      By PunchT37 · Posted

      I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.

      Parking Brake - Automatic Engagement Questions

      By SoCal Angler · Posted

      2023 GMC 3500 HD, SLE, 6.6L Gas, 4x4, 6 Spd Options:  SLE Convenience Package; Driver Alert Package 1; Spray on Bedliner; X31 Off Road Package; TRAILERING MIRRORS, HEATED POWER -ADJUSTABLE, AUTO DIMMING, WITH TURN INDICATORS WHEELHOUSE LINERS, REAR INC. REAR AXLE - 3.73 RATIO INC. GVWR, 11,350 LBS. (5148 KG) INC. FRONT AND REAR PARK ASSIST, INC. ULTRASONIC     I have been launching my new boat and noticed some things related to the parking brake.. I usually set the parking brake (habit) when on flat ground for typical driving.    When backed down on the launch ramp to launch the boat and I place gear selector into Park, the parking brake activates automatically. My second nature is to set parking brake manually and noticed I was turing the parking brake off.  The parking brake appears to be setting itself automatically.   I looked all over my owner's manual and only found references to being on an incline and manually setting parking brake, or at times parking brake will be auto engaged, but nothing specific to my situation.    When is the parking brake automatically engaged?  Under what specific circumstances?  Can the auto set parameters be changed?     I like the auto set feature.  It would be nice if always engaged when shifted into Park and released when shifted out of Park (like my wifes 2025 RAV4).   Thanks!
