Anyone know what this noise is? It's very intermittent. Seems to do it most often between 40 and 50 MPH cruising with maybe a slight up hill. Never does it on coast or heavy acceleration. Very hard to tell where it's coming from.

Should have started with that.

It's a 2014 Sierra Denali 1500 with the 6.2. Crew cab, 5'8" bed, about 118,000 miles.

I cant hear what you are describing. Do your rpm's normally jump around like that?

The noise I'm hearing can be heard at 2 and 14 seconds in the video. 

 

I noticed the tach bouncing but was sure if that was normal for this truck or not. I'm climbing a slight hill in the video and the bouncing doesn't seem to be tied to the noise but it could be related.

I also put chassis ears on the truck and you can definitely hear the noise in the T-case and rear axle. It sounds different but the intensity is about even.

I did not hear the noise in the frame, exhaust, or front axle and it was hard to tell if I heard it in the transmission.

      2017 Chevy Silverado 1500 4X4 Goes into gear but won't drive
      By ChevyGirl777
      Hello, I have a 2017 Chevy Silverado 1500 4X4, 110,000 miles, was driving down the road and suddenly stopped moving, truck still on but won't move. Goes into drive and reverse but wont move. No check engine light, transmission fluid full, and clean, no crazy noises. Any clue what it could be? I have been told the linkage, or the transmission pump... Any advice is appreciated.

      6.6 Duramax Heating Core Leak
      By Cross1992
      Hello, 
       
      I am about to buy a 6.6L Duramax 14' 2500hd Sierra with 136K on it. But I just learned it has a small heating core leak, the dealer is replacing the whole core prior to purchase. Should I proceed with this purchase? Or is this the sign of this truck going down hill. The service recorded were regular until 2018 then the car fax no longer shows any updates.  
       
      Any help would be appreciated, I have a 92 Sierra with a 5.7L small block so the diesel world I am not as comfortable with. Also do not want a newer truck as I do not want to deal with DEF and I would not be able to do a delete.

      2020 Silverado 3.0 LM2 Engine/Trans Failure
      By Jake_Melvin1
      I have a 2020 RST with the 3.0 LM2 Duramax with 79k miles… the flywheel failed when I was driving down the highway and left me dead in the water.. I had it towed to the dealership 4 weeks ago and they called today and said the transmission and the engine needs to be replaced. Has anyone experienced this with their trucks? I never towed anything heavy and was religious with service.. luckily all covered under the 100k powertrain warranty…

      Best 2022 Silverado 1500 6 Inch Lift?
      By KT47
      I’m looking for the best 6 inch lift for this truck. I talked to a local suspension shop for an install and they spooked me on Rough Country - they stopped installing them due to poor quality and many after install problems.
      would very much appreciate any and all input - truck is a brand new build and I want to do it right.

      Need help diagnosing noises coming from my 2020 Silverado 1500 5.3L
      By Sir_Griglesworth
      Hello everyone. I've recently purchased a 2020 Silverado 1500 from a dealership. I found out late in the sale that the truck was used as the dealerships "loaner" which didn't really bother me even though I know people beat up those vehicles. Anyway, I'm pretty in-tune to vehicle sounds and I had a couple of questions regarding noises I'm hearing from my vehicle. 
       
      The first is a clunking noise and a physical jolt when I shift from Drive to Reverse. I have my foot on the brake and am on a flat surface. I notice it a lot after I've been driving for a while and go to back into my garage. I took the truck back to the dealership and they chalked it up to bad U-joints. They slapped 2 fresh sets on, but I've still go the issue. Any ideas what it may be? I don't feel like anything is going to fail, but I also don't like the sound and don't think it should be that way. I have another service appointment next week and I'd like to help them out with ideas considering they don't really seem to care.
       
      The second is a ticking noise coming from the undercarriage. I' got under the truck today and believe it's coming from the rear portion of the engine, but I'm not for certain as I've never been beneath the truck while it's been on a rack. The noise cannot be heard when standing at the front with the hood up, but I can hear it very noticeably when standing at the driver's door. I do not hear it as the engine is heating up, but that could be because every other component under the hood is loud as h*ll while the truck is heating up. Once the engine is approaching operating temp, it's very noticeable. As you can hear from the short video, it's every .5 to 1 second or so and is always present during idling. Again, may not be a big issue, but I hate hearing things on my vehicles that I can't attribute to something else.
       
      Thanks for reading my ramblings. I can try to post longer videos if anyone needs. Thanks in advance!
