    The dealership is willing to replace the shocks for me, if you can tell me what shocks (and polyurethane bushings) you used in your replacement.

    I am SO anxious to get rid of the vibration. Please share the name, identification, etc. of the shocks you used for replacement.

    thank you... g

    Have a knowledgeable mechanic double check the phasing of the u-joints on the driveshaft(s).

    Here is what I did on my non-MRC Silverado:
    The fix, the tech used on his own truck, and at his reco I used on mine, is to replace all four shocks with Bilstein shocks ($396 for the shocks alone).
    The reason this fixes the problem is that newer trucks have bigger wheels and tires (more weight) and stiffer tire sidewall that don't damp vibration like the old 60-70 series tires. In addition GM specs out a OEM shock that has a single valve for both compression and rebound versus Bilstein (as well as others have two valves, a different valve for each) The way he explained it to me (known to GM engineers) is that with only one valve there is very little/none damping in the first inch or so of travel and therefore lets road irregularities set up a vibration in the chassis, undamped by the weak/cheap OEM shocks.

    At the techs recommendation I also replaced the control arm and body mount bushings with MOOG poly Urethane bushings. He also suggested sway bar bushings and spring mount bushings but they were no available at the time so I skipped those.

    FYI my truck now runs smooth as silk up to over 115 MPH (I have a diablo tune that removes the 98MPH speed limiter). I can't say all vibrations are the same but in my case and my techs case this was a definitive fix.

    Good luck getting a dealer to actually install a permanent fix. They will balance tires and give it the "sunshine treatment" until you decide you can live with it.

    I am sold. If you said it.

    GM, keep throwing Customers away because there are no problems. And you hold the Largest Market Share of any Auto Manufacture, you Can afford to lose a few Customers!

    Re: 2016 Yukon Denali- Great Car/BAD vibration

    Last year I intended to buy a new 2015 SUV 4x4. I have owned GM vehicles continuously for more than four decades. I looked at a new 2015 Tahoe but did not like the third row seat space. In March 2015, the 2015 Tahoe had already accumulated six safety recalls and the model year was not over. That was the deciding factor.

    I bought a new 2015 Ford Expedition Limited 4x4. No safety recalls. No vibration. This was my first Ford.

    GM still has wide quality and safety issues. It cost them a long term customer (me).

    Every time I read of the vibration problems in the new GM trucks, I am so glad I didn't buy one.

GM said it was normal and they all do it, etc. I fixed it on my own with some guidance from a GM tech. It cost $423 in parts with my labor. But now it rides like a dream.
    Going belly-up is more expensive.

    Oh wait! It isn't! because nobody's neck ever sees the guillotine.

    They're taking hits to trade their vibrating Silverados/Sierras in on Rams, F-150s and Tundras.
    New GM=Old GM. This sort of "bugger off!" attitude and mechanical ineptitude can cause catastrophic failure.

    That's what I'd probably have done. After going up the chain of command, hopefully getting a registered letter delivered personally to Mary B.

    I have limited patience for getting jerked around and being glad-handed.

    Oh! I don't know if this number is still good, but when my GP GXP was having issues I fished around and found a GM Case Manager. The "service" department told me "AM radio is on the way out. Get used to it. You have ______ (whatever that prescription service is that I never use).

    1-800-462-8782 Those a-holes were singing a different tune next visit, presumably after Mr. Case Manager 'splained things to them.
    They couldn't wait to pucker up and kiss my ass 20 times per visit after the Case Manager had finished with them.

    And it took a few more visits, because they were too proud or inept to send the car to a radio specialist.

    There is a big difference buying a vehicle at the end of the model run vs. one at the beginning of it's model run.

    You're correct. That was also a factor in my purchase. I bought a new 2014 Impala 2LTZ the year before (to replace a 2012 Impala LTZ) and had a significant number of defects starting the day my wife drove it home. It also underwent three safety recalls. The poor quality and recalls on that vehicle drove me to Ford.

    The NHTSA site shows the 2014 Impala model had 12 safety recalls. Terrible for a new model.

    Another critical safety recall for the 2015 - 2017 GM trucks: http://www.freep.com/story/money/car...-bag/90125616/


    Third year into the new truck model and GM is still having recall problems for a critical safety system.
