My stock bottoms rubbers are round like that first pic, and the others are square as in your pics. If the leaf spring replacements are the same and the rubber is actually different, that’s just stupid for them to replace all of it and not just the rubber spacer.  My truck didn’t make noise until after 5k. I think yours will be noisy again, but you can tell us if I am wrong.

I’m gonna try the inner tube trick this weekend

Tubes work, but the key is in how you cut them and where you place them as the leaf springs not only move up/down, but side to side as well. This movement could push them out, but when they stay in it

Just did the rubber trick on my 2019 GMC Canyon and it worked great and simple as well took about 20 minutes. Jacked up the rear of the truck so springs would not be engaged, removed wheels (you could

Here is a video i took today of the noise my 2018 Chevy Silverado with 6400 miles makes. I have had it exactly one year.

Rickety rackety camera mount noise didn’t help. Clean and superlube your leaf springs, all of it and between leaf springs. 

 

Show me how you mounted that Gopro.

He He, the go pro was mounted securely, did you see any movement in the video?

It was clamped to the rear bumper with a very stiff mount I purchased just to get this video. I am uploading another video now and will post it soon.

Sounds like leaf spring slap. The sound likely travels the frame making it seems like a weird sound for leaf springs. I placed a piece of dirt motorcycle tubing between the leaf springs and the noise went away.

Thanks Logroller

I am not really wanting to work on a truck that I paid alot of money for to put a band aide on so it doesn't make any more noise

hopefully it can be fixed by the dealer

Hopefully they can for you, but like me and many others, so far and for years there is no GM fix. At least there isn’t a TSB that is public. I asked again on my rig this week and the answer is still....nothing. Some people are going after market, some do what I have done (20 minutes of your time), others have dealers clean and lube and others have their leaf springs replaced. The first two seem to resolve the issue and the the latter two seem to always result in the noise coming back. But don’t let that stop you. I want a fix from GM as well.

This is what i did for a temp fix.

The problem is, the grease collects dirt and the problem comes back. Had the dealer do it a few times. Seems like if they improved the rubber pads, problem may be solved. Take note, cover the screwdriver or pry bar with a shop rag to reduce leaf damage.

i've read the clunk issue alot. i have it in mine as well. from what ive read an im gonna try is the 2.5 ubolt addon. which is basically hit ur local parts store get a 2.5in set of ubolts. put them over your leaf spring say 5.5 to 6 in in front of axel on both side .n torque to 80lbs as well as re torque your factory ubolts to min 80ftlbs to 100 max. apperently this is tried tested and works. parts are like 10$ so worth a shot.

I took mine to another dealer on monday and they were able to find the new service bulletin about this and are ordering the parts hopefully this will fix the issue. I also emailed the other dealer that would not do anything about the problem and let them know that their service writer didn't do any research on the solution for this problem even after I told him that there was a new part that should fix the problem. I then got a call from them and they told me that they found the new service bulletin and were sorry about not giving me good service.  GM doc #5084607 is what they put on my work order.

      Transmission Woes :-(

      By newdude · Posted

      You need a better code reader/scanner.  You are missing codes.  Did the dealer give you a copy of the SAVI scan from that visit?     If the fluid hasn't been changed, change it.  Shudder will likely go away.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By newdude · Posted

      TLDR to my other post...   Hard. Pass.  Too many what ifs.     Are you set on a 3.0 Duramax?  Have you considered anything not GM just in case?  If you don't have to have a pickup, lots of other options for $27,000 out there.

      I see some red flags.   - No mention in the Carfax if the oil pump belt was changed.  LM2s had a 150,000mi service interval, and its got 164,245mi on it.  So right out the gate it needs about $3000-3500 for that to be done before driving it another 150,000mi.  Belt is at the rear of the engine.     - If something happens to the transmission valve body, the special coverage is expired by mileage.  That will likely be an out of pocket expense, with zero or near zero GM participation if something happened even though its in by time.   - 2020 LM2s seem to need timing chains after 80,000mi at some point.  They fixed this end of 2020/starting 2021 model year engines.  They will usually set a P0016 I think?  There is another $8000-10,000 if it needs a chain.  The main chain is at the back, secondary at the front so the pump belt would be done at the same time if it needed chains.     - Long oil change intervals.  7,000-8,000mi on average, probably close to 0% or perhaps to or beyond 0% on the OLM.  Lots of them not at the dealer which makes me wonder how much of the oil ran through that truck was the proper Dexos D rated 0w20 oil and not just gas engine 0w20, which is not the same at all.     - Long fuel filter changes, again likely taking the fuel filter life to 0% or more.  First one went 28,603, second was done 43,094 miles later at 71,697, from there another 46,452mi to 118,149mi, and then the most recent one 37,026mi later at 155,175mi.  So counting its original fuel filter, its had only 4 fuel filters on it.  No bueno IMO.         Good news?    - It has had only two warranty trips to the dealer.  The first free service (end of December 2020 on the Carfax), and the transmission reprogram recall (end of August 2025 on the Carfax).     - Truck did a LOT of moving, so that might explain the lack of emissions related repairs like bad NOX sensors, bad exhaust temp sensors, bad glow plugs, etc.         The "emissions system checked" could just be how something was flagged for Carfax.  GM dealers have to do SAVI reports for warranty repair orders so they scan the truck.  So its possible that is there for that?

      Thank you, @Z45!   NOTE - No all repair shop/Dealers reports to Carfax   That is my main concern.  The CARFAX looks way too clean for a 6 year old anything with 164,245 miles.  Even something known for reliability (like many Toyotas) typically has a lot more replaced, like a Nav screen, interior trim, shock/strut, or brake pads.  And surely the last set of tires (installed at ~58k miles) would be bald unless those were all highway miles.   I'm tempted to pay a local dealer to look up the VIN, but am not sure if that will be worthwhile.  Last time I did this, it was 100% useless, and I felt scammed - they noted the bumper was replaced years ago and that's it.  A 5-year old could spot the accident damage, even though nothing was on the CARFAX.   After giving the dealer a call, the truck may have a hard shift, but they have to verify with their mechanic if that's even a concern.  And I've test driven about a dozen of these now, many near Chicago, and half the trucks shift hard/odd at all throttle positions.  The ones with aftermarket lifts/larger tires shift terrible, and 3 stock trucks shifted so violently I thought the transmission valve body was going out.   At this point I'm conflicted, as I need a vehicle, and am coming up short locally.  Northern trucks in this price range tend to have either multiple owners, a lot of mods (lifts/oversized tires without re-gearing), and are generally in rougher shape.   If this truck showed up in your neighborhood for $27k and you had to purchase it sight-unseen, with the possibility of needing a 10L80 rebuild, torque converter, or rear end - would you do it?  I'm convinced most of the 10L80 trucks I test drove are broken, they can't all shift so bad, with massive flares/slipping/lurching and mis-matched downshifts like a teen driver learning stick.

      2027 GMC Sierra Spot Shots + Undisguised Interior (BIG Changes!)

      By Griffin Donovan · Posted

      From the spy shots, the front end does look like it's borrowing some styling cues from the Canyon. I'm more interested in the powertrain news than the screens though. If the 3.0 diesel survives into the next generation, that alone will keep a lot of current owners interested.
