Power steering whine

Would not be surprised if many of the noise guys have the NV8 digital assist active hydraulic steering.  NV8 is on LTZ, High Country, SLT, AT4 and Denali.

 

If so, noises are totally normal.

 

#PIT5544E: Normal Characteristic - Hydraulic Rush Noise from Power Steering Gear - (Sep 1, 2021)

Subject: Normal Characteristic - Hydraulic Rush Noise from Power Steering Gear

 

Additional Options (RPO)

NV8

Condition

 

Some customers may comment on a hydraulic rush or flow type noise from the power steering gear. This noise is a characteristic of the new Active Hydraulic Assist System RPO NV8 and no repairs should be made.  The noise is most noticeable in the cab at idle, in park, with all accessories turned off.

Thank you - thats the same document I was referring to.  I am by no means a mechanic, I definitely hear the rushing noise.  Seems separate from the whining noise to me though.  Perhaps they are related.  The whine is very apparent and different.

I’m on my second ps pump. Dealer agreed with me on the original and replaced it. The replacement was quite for about a week then the whine was back although not as loud as the first one. I can’t tell if it really helped but I took a squeeze bulb apperatice and sucked all the fluid I could get out of the pump and refilled with Royal Purple ps fluid. I drove it a couple days then repeated the process. Mine is tolerable but not as it should be.

I have a 2022 LTZ 3500HD 6.6 Gas and i only have power steering whine when i have the steering turning full left or full right. Then i get some annoying whine. Other than that i dont hear it.

I know this is kind of an old topic but I had this on my 2022 custom 2500 gas model.  I opened the power steering cap at 2500 miles when I first noticed it, nothing on the dipstick.  After a full pint of power steering fluid, it quieted down, back to normal.  I don't think GM serviced them correctly from the factory or at least made sure all the air was out of the system.  And of course it wasn't checked at my first oil change.  If it was it would have been caught a few hundred miles earlier.  But either way my noise was from lack of fluid.  16ozs later it's showing up full on the dipstick and all is quiet now at 4k miles, thank goodness.

Hello I have a 2020 Chevy Silverado 2500. Our truck has the same steering whining noise. It becomes annoying at times. We do not hear the whining at normal operating speeds. We only hear the whining while at idle and maneuvering the truck. We have had it to the shop several times and they tell us that this is normal. The truck drives and handles properly and stays true to the road. We also have the same issue with the NAV card. A message pops up and says SD card has been removed. Nobody at the dealership could figure out why. I had to figure it out on my own. The USB module in the dash was causing the issue. I pulled the USB module out and found a loose connection on the back of it. After securing the connection, the problem went a way with the card issue and did not return. I figured this problem out approximately a month ago and have not had an issue or a message since.

Mine had whining, the pump was low on fluid. Filled it and the noise went away. Else remember the power steering pump is your brake booster.

FWIW

 

The whine was driving me nuts too and it started at about 5000 miles.
 

Dipstick read right in the middle of range. So I sucked all the oil out which was VERY DARK (while rotating the wheel all the way left and right). Then I flushed it with new oil (siphoning and refilling). Since my mechanic friend said I should add a leak additive, I added: 


Bar’s Leaks - Power Steering Repair

 

And finished with it filled to the top line of the dipstick. 
 

Happened to be taking a 300mi drive the next day. When I arrived the sound was much quieter.
 

Sounds like it did from the factory.

      Gas fill door

      By newdude · Posted

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      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.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      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?
