Drivetrain Vibration in 2014-2018 Silverado & Sierra Troubleshooting Posted May 31, 2019 The horrible vibration on my 15 CC was corrected by installing new Yukon Axles (rear) and rear rotors and pads. The driveshaft was balanced, but did not make a huge improvement. Check out the lack of mating between the axle and rotor. That will show just how bad the flange is off. The vibration was crazy betwwen 70-80 and could not go above that speed. I knew it helped as soon as I replaced them, now I just hear tire noise. The entire resonance of the truck changed.
