2017 Tahoe - vibration / Buzzing sounds on acceleration

[Barakawins]

I have this weird issue with my 2017 tahoe. Seems like when accelerating and maintaining the gas pedal at a level speed on the highway, I'll get what
sounds like a buzzing/vibration sound. It's similar to when you drive over the ridges on the highway to prevent falling asleep but no way near that loud. It's minor but only happens around 60 mp around 1500 rpm and steady speed. When you lay off the gas it tends to disappear. I also noted when breaking at higher speeds, there's a pulsing of the brakes similar to a warped brake rotor. Anyone experience this? I'm starting to think this is a bearing problem with the front ends. When I drive the truck around town there is no issue with any noises or pulsing when stopping.

The vibration on acceleration and maintaining speed is something I’m fighting with on my 14’ Tahoe I have a form on it as well so far haven’t found what it is, but definitely feels like a rumble strip

Transmission Mount or U Joints come to mind.
Take a floor jack and lift the transmission (with a 2x4 or 2x6 between the jack & tranny) and see if it lifts a little and exposes a busted mount. If so replace the mount.
Grab the drive shaft and try and twist it or turn it or shake it, push it or pull it and see if there is slack or movement. If so maybe the U joints are/have failed, replace front and rear accordingly.
Make sure the weights on the drive shaft are still on, see if there is evidence of a missing weight like discoloration or a cleaner/shiny'er spot. If missing you will have to have the driveshaft rebalanced.
Lift the front end and push the top and bottom of the tire & right & left of the tire to see if you get movement, if so then replace the wheel hub assembly.
Check the Wheel Weights and make sure they are still there, if they came off they will usually leave white sticky tape residue on the wheel.

That's all I can think of, let me know if that helped or if changing the windshield wipers fixed it!! LOL!!
