Just wondering if anyone else has noise coming from the rear axle or bed or suspension when navigating bumps and in reverse. Is this normal? Is it not? Does anyone else have the creaking squeaking bed noises? Thanks

Yes - I have a 2019 RST z71 with 700 miles. I love the truck. Engine is strong, transmission smooth and I like the Bose. Took it to the dealer today to report a noise under the bed whenever the truck is on an uneven surface or say a speed bump. The shop foreman heard it and they decided to keep it and gave me a loaner. He said he was going to check hangers and leaf springs. I have since googled leaf spring noise and read several articles. I will report back but thought I would share. Like you, I would like to know if others have heard this noise. My truck did not do it when new. Good luck!

My strange noise turned out to be my power steps rubbing on frame bracket.

I have a popping noise that occasionally comes from the new designed spoiler on the back of the cab where the third brake light is.  It is plastic and is not loose so I believe it could be flexing somewhat and causing an occasional pop.  Anyone else with this one issue?

My truck has a "snap!" sound but I haven't located it or have any specific reason for it to happen, just every once and a while kind of like a stone coming out of a tire.

I've had the "popping" noise from the rear roof area a couple times turning slowly over large bumps. Sounded like a small acorn dropping from a tree and hitting the roof. I figured it was just due to body flex in that area, perhaps the plastic "spoiler" is flexing and making the noise. Nothing looks out of sorts, so I'm assuming it's just normal. My 2011 Ram used to squeak and pop all the time, I became used to it.

I like your description of the sound I have, but I would like to find out what causes it and fix it.

ours will make noise in rear brake area. but only seems to be first movement of the day on a uneven stone drive, but seems to be everyday....weather wet or dry out

I also get the spoiler popping.  I figured its CTE since I park inside a cold concrete parking garage during the day and usually hear the noise on hot sunny days heading home from work to get my kid.

 

For the OP, when I put on my cheap nerf bars I noticed some extra creaking when I went over big bumps slowly (i.e. concrete ramp into driveway).  I retorqued the cab bolts going through the nerf bar brackets and its since gone away.

My truck is a 2019 AT4 

Just started hearing this noise on my AT4 when going over bumps. I'm at around 1k miles now. It sounds like a hollow squeak. @AT4guy, did you ever get yours resolved?

I just took my truck in for an oil change at 7400 km’s And had them check into the squeak I have now in my 2019 AT4. It’s very annoying and embarrassing for a brand new truck. GM says it’s the leaf springs and there is a fix for it. Some kind of spacer and new u bolts that they ordered for me. Will update once it’s been fixed.

 Same issue.

UncleDave, I have same sound coming from my 2019 RST Z71. I was going to explain in same way as if an acorn dropping from a tree. Hoping we can keep this thread going until we identify the source. Thanks

So was that the problem?  My truck just started doing this. Sounds like a creaking noise when turning off onto uneven pavement. Sounds like it’s coming from the rear. So it may be the springs.   

 

Did tou you ever get yours fixed/figured out?

    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?   
    • Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter
