    Re: Highway Shake

    Thank you for the update.

    My 3500 has always had a real mild shake motion at highway speeds.

    It's been a long time since I owned an HD truck, and since you don't buy 1-ton trucks for the ride necessarily, I figured it was the price you pay for capability.

    I had the tires rotated and balanced several times, and it never went away.

    Tires are the stock Firestone Transforce AT on 20-inch rims with 23k miles on them.

    I finally saved the cash for a nice aggressive Toyo mud terrain in stock size, and after reading your post, I can't wait to see if that shaking goes away.

    I realize the M/T will be noisier, and the overall ride quality won't be as smooth, but having that little wiggle/shake motion gone will be heaven.

    Much later update on this.

    I currently run Mickey Thompson ATZ P3 tires and have gotten a recent alignment.

    The truck drives straight and smooth as high as 90 without realizing how fast I'm going.

    So maybe it was a tire/alignment culmination.

    I have 2020 3500 all stock; the seats shake at highway speeds also.

    It's been to three different shops.

    All said, the suspension, alignment, and tire balance are good.

    With only 15K miles on my 2017 - & the Horrid OEM Firestone (Transforce) tires still looking fairly new - She has had a very slight vibration as you all speak of @ 60-90mph.

    I figured this was due to the ancient design (Solid Axle) below - My Co-workers New Duramax with the (IFS) was exceptionally smooth - I drove her for about 20 miles on our Horrible Oklahoma Highways.

    I can live with it - Maybe in time - I can upgrade some of the front suspension with aftermarket to help cure this.

    (Maybe a Double Steering Stabilizer kit) --> Just thinking out loud!
