Has anyone noticed their power steering making a moaning noise when hard over either direction? Wondering if this is normal. I have never had a vehicle make so much noise when having wheel cranked. Almost like fluid not flowing correctly. I have not checked power steering fluid level if there is such a check.

Normal especially if it has the digital assist which pretty much every crew cab HD this gen 2020-2026 has.

How would I check if my wt has that? Hopefully not I don’t like options.

I'm under the impression WT/Custom doesn't get it.

Yeah, my power steering flow sounds like it has air or rocks in it from day one… any pressure on the steering wheel in either direction it hisses and bubbles…sounds like this L8T is an L5P. I need to bring it to the dealer before the warranty runs out. From reading other responses though I’m afraid that’s just normal…. I guess the other option would just be to go test drive a comparable truck and see if it makes the same noise… but that still doesn’t fix it. I assume it is like others have said and related to the digital steering assist  (RPO code NV8). 
 

Did find this though:

For the 2020-2023 only the LTZ and above trim got the digital. Don't know about the 24+ but it's probably the same.

 

Use only PS fluid, not ATF. The system can be bled although it's potentially messy and doesn't look super easy. PS fluid expands so there is a cold and hot check mark just like the transmission. Check with engine running. 

 

You want to really hear it groan? Strap a stabilizer and some 35psi 37" tires to it and do a slow speed full lock turn 😆

correct it is LTZ and above that get digital....had a 2020 and 2022 LT and it hissed and bubbled at full lock and only had std standard steering, owned a 23 HC and currently a 24 SLT both with the digital and don't notice it as much and or maybe just dont use full lock......could be I am just used to it though, the steering is definitely noticeable at slow speeds between the 2.... like a 1500 with digital..

I don’t recall ever needing to crank the wheel to full lock. Ever. So I’ve never heard anything out of the ordinary.

Updating this topic a bit as I just noticed OP has in his signature that they drive a 2025 LTZ Trail Boss, so it would have the NV8 digital steering.

      Joke Thread

      Of course refrain from political debate but I myself have very dismal hope for what is all going on up here every where we turn so I nodded my head when I saw this joke.

      I'm looking at carpal tunnel surgery on my left hand and lumbar fusion.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      While waiting for parts I have been working on installing the AC compressor, new accumulator, and orifice tube. Also changed out the high side ball valve (original). The orifice tube that was in there wasn't too bad. Slightly dirty, a little bit of junk, but not blocked. Glad I changed it out.   The accumulator, which should have been a 5 minute job, may have just burned $50. Put some PAG in it, wrote the date and mileage on the side, fresh o-rings and gooey'd up the threads and rings with Nylog. Got everything connected and snugged and was going to vacuum down the system, and....   My manifold gauge won't fit on the port. It's not an R12 service port. It LOOKS like an R134 service port but the diameter is a hair too large. There's a sticker on the accumulator that says it's designed to be used with R12 and R134a systems only. So it's not R1234yf. Even if I reduced the diameter slightly with a file, the shoulder on the port is too large so the quick-connect valve won't lock on. I'm stumped. It's going back, and 50/50 on if they'll give me a refund.   Also, I did a fuel pressure test.... Key on, the gauge spikes to about 60psi and quickly bleeds off, like 2psi per second. The fuel isn't going into the plenum, no smell, starts fine, so I'm guessing there's a bad check valve in the pump and the fuel is just draining back into the tank. oh, hell. But, it shouldn't be a problem, pump primes just fine and the truck starts right up. It just means I can't really ever use fuel pressure to verify a leak at the injector or intake.

      SERCICE ESC message?

      By No F-bdy Bs · Posted

      Got this yesterday out of nowhere. Truck is a 25',6.6 gasser with 8k miles.  Only semi anomaly is that the truck had been sitting, uncranked for 6 days. Elec Stability Control showed immediately upon cranking, not while driving. No drivability issues, just the message. Battery didn't seem to be weak when cranking over.  I drove it, killed it, let it sit a few hrs with no avail.  Truck is 100% stock. No damage.

      on-wheel cellphone control: 2026 1500 WT (2.7L 4WD std cab)

      This can be done.  It is not cheap and requires an instrument cluster swap with custom programming, new steering wheel with the controls on it, and a special jumper harness.   The cluster upgrade - 12.3” Digital Cluster Upgrade – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The wheel upgrade - Steering Wheel Upgrade Kit – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The column harness upgrade - 2019 - 2026 Silverado / Sierra: Steering Wheel LIN Bus Harness - Harness Dr. - DIY Done Right     The problem with doing all of this?  You pretty much can't have any programming done to your truck that involves the cluster ever again.  The dealer won't be able to program the cluster as GM's system will only pull data for the cluster the truck came with.  So it would be advised also to turn off over the air updates.   TLDR;  Should have bought an LT double cab?  You'd have a power seat, the wheel controls, the cluster, all things that you've been seeking in your various posts so far about your new WT regular cab.
