Rear end (leaf?) noise explained?

Not sure if what I have is the same as others.   When I go over a bump at slow speed I get a "noise".  Not sure I'd identify as a clunk.  I jumped on back of truck and can hear it a little.   HOWEVER... if I shake the truck side to side by grabbing the bed rail I hear it.  From what I can tell it looks like the leafs are sliding side to side.   On my Jeep (Wrangler YJ) the leafs have clips of sorts to keep the leafs stable.  

 

Thoughts?   Is it the same issue other are having?

More than likely. I’d try the rubber trick first before wasting my time at the stealership but that’s me.

Rubber will wear out.   I've looked at the '19s and the springs have clamps on them.   If I report to dealer and it is documented then if an issue later I have at lest documented the issue.   I'll prob. report to them and then do the rubber until a recall (hopefully) is done.

I thought that was interesting on my 2016 that there aren't any clips and it looks like one of the leaf springs aren't completely flush with the other and sticks out a bit.  I have the noise too and on 2 occasions they just tossed a bunch of thick grease between the leafs to take away the noise.

Noticed the same with mine. And the springs on the 2019s seems to have fixed this issue. Have you been to the dealer recently for it? I read of some people having theirs replaced entirely.

Was at the dealer last week for my leaf springs, no additional fix beyond greasing them.

Did they give you any push back because of your lift?

None at all. But I did purchase the truck with a lift on it from the same dealership that I have my warranty work done at. I have talked to another dealership, that’s a little closer to where I live now, and they have no problems with working on the truck because of the lift. But at the end of the day any dealership could claim they will deny the warranty or not work on a truck because it’s lifted. Legally, they can’t do that. But if that’s their attitude then they probably aren’t worth the hassle of convincing them to work on it. My advice if you need warranty work performed on a lifted truck find a dealership that sells Rocky Ridge, ALC, SCA, or homebrew lifted trucks; they will definitely do warranty work on lifted vehicles.

Yes I have been to the dealer twice and all they have done is retorqued and lubed up between where the leaf springs rub.  The noise goes away but I cant imagine for long and I'll be back for a 3rd time.

I have the same noise. I  talked to the service adviser yesterday when I had my oil changed. He reproduced it like you did, by shaking the truck side to side. He said it was the 'floating axle' and that it's normal. I did mention TSB 18-NA-183, so they did check and said it was greased fine.

Anyone else get the 'floating axle' explanation?

The axle shafts are held inside the axle tubes by C-clips inside of the diff. When there is a little play, the axle shafts can slide side to side just enough to make a noise. When you push sideways on the truck, the axle shafts (attached to the tires) are held in place, so the whole axle housing (shafts and pumpkin) slides sideways.

It's a normal characteristic of a semi-floating axle. Some make more noise than others depending on tolerance stacking.

SO... found the issue...  Shock bolt broke or came loose and the shock... well... see the pics...   :/

 

I then went to the local dealer and looked t a few used trucks and 1 of 7 had a loose shock.   Bolt was still there but was loose.

Thank you for the detailed explanation. I wasn't sure if I was being hosed.

      I forgot to answer the question as per what market mine is set to and yes I finally found that area on mine and yes its also set to America.   So here's something I realized as I wasn't looking at that part in the Sierra section until now, your right that what I see here as choice 3 under Sierra which says 07/2023-06/2026 ( 433 MHz 13542523 ) it has no choice 5 for tire pressure selection. Where as it does under the Chev choice. However I kept going down the list within the Sierra and I am really wondering if choice 9 will work for your truck as it has the same model number and hertz sensor as my truck. I would say try that choice first, if that doesn't work then jump over to the Chev section and again choose that same model and hertz choice as for some reason the Chev section gives the choice 5 of tire type/pressure selection for going back a number of years. Could very well be an Autel thing that they just didn't get the updates all done properly under Sierra but anyway first try that selection 9 I suggested under Sierra and then go from there.

      Anyone have a spare?

      Looking for this piece that holds the hose clamp in place. I have the hose clamp just not that other piece. Dealers and wrecking yards in my area will not sell just that piece. They want you to buy the whole air tube $100 +/- to get that $5 part.  that piece isn't molded to the air tube as I looked at my friends truck. It's held on by a screw and nut. I'm trying to put the OEM parts on the truck as the previous owner butchered things up installing an aftermarket CAI. It really looked homemade. 🤣 Thanks

      Ok I missed that part that yours is a GM. The strange part is that the choice for year ranges and within the year of 2026 is different on the Sierra then on the Chev for some reason as I am looking at my tool at the Sierra choices. Now I am guessing you see as to your sensor part number as it may be different on your truck for some reason and a call to GM should get you the part model number of the sensors you should have as well as which MHz your sensors are. I know mine are the ones as per what I listed but there are other choices in the Autel and got me wondering if by some chance they put different ones in your truck. Having said that, did you try using each of the choices starting from No 1 and going on down the list, not sure if that would mean shutting off the engine each time and resetting the tool and going at it again each time. Also I thought of something else which may sound retarded but if there was some stupid chance that the chev choice would work. The reason I say that is that the Sierra is showing a range up to 06/2026 for the various choices of sensors it could be where as the Chev has one choice that has that 12/2026. By the way it is possible to not run the truck and you may know that as per not pressing the brake but pressing and holding the start button for a few seconds and it lights up the dash ( its called service mode ) but that sucks battery power and if it were me doing it that way I would be throwing on a decent sized battery charger before doing it that way as killing your battery won't make you happy at me at all !.    Like I say, just a thought to try the Chev choices if you have already exhausted the Sierra choices but first it would be nice to know for sure what exact sensor model and hertz your truck uses as I assume only those choices that mention the sensor would work unless a choice that does not mention the sensor model would somehow work. Its frustrating when one is trying to use tools like this without the experience of the tool and the vehicle, as I am sure dealer techs themselves struggle with it when starting out or a new model year comes along that is slightly different.

      I tried before I updated the scan tool just incase an update messed it up, but it never worked so I updated the scan tool and it still didn't work.   Only difference is I click on Sierra not Chevrolet cause I have a Sierra.   If I click on 2026-2024 I didn't have any option to change placard, when I click on 2023 it does give me the option but when I try to do it,.it says vehicle not supported!   I have my region or market or whatever it is set to America I think, is that what yours is set to?

      Its just that it worked on 2024 trucks on this forum and my 2025 model truck, unless GM did something since that point to screw up access or Autel has a bad update. I haven't had need to use my tool since last year when I did the changes to the placard pressure settings and since then I updated the software on my Autel but have not plugged into the OBD so hard to say if I would get a surprise as well.    All I know last year when I bought the Autel I was warned to be sure to update it before I tried using the unit as they said who knows how long ago unit itself was actually manufactured as the software could be way out of date.
