Well, damn. Tomorrow I drop my three week old 2016 Sierra 1500 SLE Crew Cab with 950 miles off for 3-5 days of evaluation for the shakes. I expected a service appointment with tire balancing or maybe even replacement. Sounds like they are going full-monty right off the bat.

It ended up being right at $650 for axles, seals, fluid, and lug nut studs.

Not bad to have a smooth riding vehicle. i'm sure GM and a dealer would say there is now way that's causing the problem but it sounds like it may be the problem. I'm going to wait until you have more time on the road with it and possibly go down the same path. The castings for the hub are just plain sloppy and I bet unbalanced even beyond just the edge of the hub face not running true I'm willing to bet the thickened portion of the casting where the studs come through are even out of whack. Its like the raw cast wasn't centered when it went into the machining center for facing and hole operations so you get a center hole with the studs properly centered but offset on the actual hub center, if that's the case you want be able to balance them by just turning the outer edge in a lathe.

Kurt,

 

Did you have the vibration right from the start or did it progress after some higher speed highway miles? I ask because many here don't witness it until a few thousand miles and some have it right away and it's hard to put a finger on it. Any imbalance would be felt right away while shifting steel tire belts or wheel balance, if that's a cause, would and could happen progressively or a different speeds.

I noticed it slightly on the test drive but attributed it to flat spots on the tires from sitting. I knew nothing about the vibration issue and called with 150 miles on the odometer. At 1,000 miles it remains exactly the same. Their response that they needed 3-5 days to diagnose prompted me to start searching for why.

I did some heavy hauling/towing recently. My bed had at least 800 pounds in it, and I was hauling a trailer with cargo weighing around 5,000 pounds. My truck still shook. At certain speeds the center console shook like it always does. Many friends always told me that if I loaded the bed it would be fine. Nope. She was fully loaded and still shook.

Where are you feeling the shake? Floor, seat back, steering wheel?

Seat and steering wheel. I could duplicate any number of U-Tube videos showing a water bottle shaking in the console. It occurs at about 50 mph and again at about 75 mph.

Called my dealer today asking for an update (been in 27 days straight) and informed me that swapping the driveshaft corrected the problem. It has now spent 38 days total in the shop and vibrating since delivery and it took them this long to try something other than tires!!! Was the driveshaft swap successful for others? I am going to pick it up tonight or tomorrow.

I had mine trued and it fixed the shake.

I can't find any place local that does that so I am looking at ordering an aftermarket one, seems like an easy place to start for me.

Update on my end. Dealership wanted to change brand of tires but GM wants an engineer to look at more PICO data. Dealership had my truck for the day while they collected more data. Apparently they didn't measure everything the first time. On another not I had a 2017 loaner double cab LT z71. The tires were Goodyear wrangler H/T's. Haven't seen this as a stock option till now? Maybe GM is going to ditch the SR-A garbage? Anyways, I hope they detect something because this 2017 rode way better. I mean night and day. No vibration in the steering wheel and I drove it for about 3 hours total had 900 miles on it when I picked it up. Asked if I could keep this one and they could keep mine Lol. The saga continues....

    • I’m out of ideas on this truck. 2020 Silverado 1500. 5.3 135,000 miles. Has a p0308 and p050d codes. Smokes From exhaust when cold. Compression test passed. New plugs, wires and coil on cyl 8. Same issue. New coil on 8, no change. Replaced injectors, no change. Bore scope showed oil pooled on the piston after sitting overnight. Pulled head and had machine shop check it out. No cracks. Stem seals looked good, replaced anyways. He also ground valve seats. Put it all back together and still have the same issue. Bore scope shows oil on the piston again. Leaning towards maybe a cracked ring but unsure. Cylinder looked good when the head was off, no scoring or scratches. Any ideas on what else I should look for?  Appreciate the help 
    • Just want to make sure it is covered by Special Coverage N232395310 Evaporative Emission Purge Pump 2021 Silverado 1500 Custom 2.7L L3B ~100k miles I'm getting DTCs P146B and P146F. VIN 3GCPWBEK2MGxxxxxx   I spoke to a person that works at GM and he said it is not covered after checking my VIN.   Is there anyone here who currently works for a GM/Chevrolet dealership and has access to GM Global Warranty Management / Investigate Vehicle History who could explain how the VIN eligibility is determined?   thank you    
    • Thanks for all that information, I might purchase one and see if it will work for me, if not they may let me return it! Yes for sure the tires are definitely within limit for my truck empty, and when I do tow I'll definitely make sure to raise the rear psi for the amount of weight that's going to be on it.
    • Yes exactly, more and more these days people/companies are afraid of liability issues so its easier just to say no rather than risk putting their neck on the line.    I will say with the Autel unit or when I used it last year on my truck, it wasn't like I could choose the 2025 model year or even the 2024 model year as that option was not there to manipulate the placard pressures but had to go back to 2023 or there abouts and then it showed up as an option, odd but that was how the software was then and I can't say one way or the other now as they throw out updates every so often. I still would talk to your tire dealer though to start with and they may do it for nothing but also they may have a comment on a better unit to purchase. All I know is that one of the large tire shops in my area happens to use these Autel units for their use and set them up to use the wifi and all of that jazz for constant updating because each tire tech has one handed to them by the shop but I just plugged it into my laptop to update it and yes if one is bought it has to be registered so you can get the link to do updates and then the unit has to be updated before its even used. I am not at all techy so it took me a bit but anyway just a heads up for anything you buy, most likely it will need to be connected to a computer to access the internet to have it updated to the latest software version before you can put it to use.   If your truck is near empty, those tire pressures you listed are a very safe upper range pressures to carry the weight, both the front and rear as I know they could be run lower yet with an empty truck. And if its a trailer and not some motorcycle your going to strap onto the front of your truck on a rack, you shouldn't have a need to inflate your front tires if your at 55 front already, its the rear ones that would need more air if you have much hitch weight. 
    • Thank you, I'll check that Autel scanner out and see if it will work for me! Ya I can see GM's point of view if they lower the psi set value for someone and the person sell's the truck and the new owner puts the factory tires back on then their could be liability issues cause the psi warning light wasn't coming on when the tires were under inflated for towing their load and then it might be able to be traced back to GM lowering it.
