Always check steering joints before changing the steering box.  Idler arms would fail before a box.  This was my problem.

Any updates to this? I have a 2016 Duramax 4x4 with 40k miles. The last 1000 miles it’s got the death wobble if you hit a small bump around 40mph or so. It tracks completely straight at high speed. It’s had an alignment  and  I checked all the front end parts and everything is tight other that the steering box. The dealer said it’s on me to fix since I’m outside 3/36 I’m pretty irritated that this happened so early. I have a 2.5” rough country and running 33s I’ve had them for 2+ years no issues till now. It also has 2-3” of slop in the steering wheel. Thanks.

I’m having same issues with my 2016 Sierra Denali with duramax. At 7k miles developed lots of slop in the steering wheel, took it back to the dealership and had the problem “solved” under warranty. Since then I have installed a 5” zone lift and 35x12.5 tires with -25 offset. Truck drove great for about 7 months and started to notice the slop back in the steering wheel. Just took it back to the dealer and said I was out of warranty with 21,650mi on it and said that the larger wheels are what did it and will cost me $1800 parts and labor for new steering box and pitman arm. I refuse to believe that a he can’t handle larger tires. And I have zero desire to spend $1800 just to get it back to stock and potentially have this issue again in a few thousand miles. Anyone have a viable upgrade solution to this issue?

The wobble your having is your brake rotors. All makes of heavy duty trucks have the same issue after getting on the brakes hard for an animal crossing the road or holding the brakes to long with a load on, basically overheating. I put a set of slotted and drilled rotors and matching brakes in the front and it all went away and never came back. Some people do all 4 but I’ve had two trucks that I only did the front and they’ve been fine. When it comes to the steering being stiff, I’ve had it on both trucks. Boys at the shop looked at it and said everything is more than tight, but the lube shop missed a couple grease nipples and that helped a lot for about 15k. If I wash the whole underside of the front steering components and brakes, it also goes away for awhile. Can’t pin point that issue just yet

So as the very first post asked repeatedly;has anyone found the actual solution (or the cause at least)?NV8 RPO appears to be problematic box code(whatever vehicle/colour/trim)TSBs issued and fix appears to band aid a problem.Where did the “play” come from other than wear.Adjust out the slack does not account for the new “space/play” that was created over time.(I assume metal filings in pump/hydro boost system after endplay adjustment made.Partial flush from box removal/replacement.Suspect the GM replacement boxes also have the same basic issues.NOBODY seems to actually know root cause(ie:gear hardness/metal deficiency/fluid inadequacies/pressure or flow problem/contamination from manufacturing processes.Endless forum guesses but zero facts or fixes and alternatives put forward.

      It's possible the two trucks are using different body control modules which is why yours works and the OP's doesn't.   So much in these newer vehicles depends on model/trim configurations, production date. They don't all use the same modules like back in the day.

      I forgot to answer the question as per what market mine is set to and yes I finally found that area on mine and yes its also set to America.   So here's something I realized as I wasn't looking at that part in the Sierra section until now, your right that what I see here as choice 3 under Sierra which says 07/2023-06/2026 ( 433 MHz 13542523 ) it has no choice 5 for tire pressure selection. Where as it does under the Chev choice. However I kept going down the list within the Sierra and I am really wondering if choice 9 will work for your truck as it has the same model number and hertz sensor as my truck. I would say try that choice first, if that doesn't work then jump over to the Chev section and again choose that same model and hertz choice as for some reason the Chev section gives the choice 5 of tire type/pressure selection for going back a number of years. Could very well be an Autel thing that they just didn't get the updates all done properly under Sierra but anyway first try that selection 9 I suggested under Sierra and then go from there.

      Anyone have a spare?

      Looking for this piece that holds the hose clamp in place. I have the hose clamp just not that other piece. Dealers and wrecking yards in my area will not sell just that piece. They want you to buy the whole air tube $100 +/- to get that $5 part.  that piece isn't molded to the air tube as I looked at my friends truck. It's held on by a screw and nut. I'm trying to put the OEM parts on the truck as the previous owner butchered things up installing an aftermarket CAI. It really looked homemade. 🤣 Thanks

      Ok I missed that part that yours is a GM. The strange part is that the choice for year ranges and within the year of 2026 is different on the Sierra then on the Chev for some reason as I am looking at my tool at the Sierra choices. Now I am guessing you see as to your sensor part number as it may be different on your truck for some reason and a call to GM should get you the part model number of the sensors you should have as well as which MHz your sensors are. I know mine are the ones as per what I listed but there are other choices in the Autel and got me wondering if by some chance they put different ones in your truck. Having said that, did you try using each of the choices starting from No 1 and going on down the list, not sure if that would mean shutting off the engine each time and resetting the tool and going at it again each time. Also I thought of something else which may sound retarded but if there was some stupid chance that the chev choice would work. The reason I say that is that the Sierra is showing a range up to 06/2026 for the various choices of sensors it could be where as the Chev has one choice that has that 12/2026. By the way it is possible to not run the truck and you may know that as per not pressing the brake but pressing and holding the start button for a few seconds and it lights up the dash ( its called service mode ) but that sucks battery power and if it were me doing it that way I would be throwing on a decent sized battery charger before doing it that way as killing your battery won't make you happy at me at all !.    Like I say, just a thought to try the Chev choices if you have already exhausted the Sierra choices but first it would be nice to know for sure what exact sensor model and hertz your truck uses as I assume only those choices that mention the sensor would work unless a choice that does not mention the sensor model would somehow work. Its frustrating when one is trying to use tools like this without the experience of the tool and the vehicle, as I am sure dealer techs themselves struggle with it when starting out or a new model year comes along that is slightly different.

      I tried before I updated the scan tool just incase an update messed it up, but it never worked so I updated the scan tool and it still didn't work.   Only difference is I click on Sierra not Chevrolet cause I have a Sierra.   If I click on 2026-2024 I didn't have any option to change placard, when I click on 2023 it does give me the option but when I try to do it,.it says vehicle not supported!   I have my region or market or whatever it is set to America I think, is that what yours is set to?
