A wavy of Vibrations as i drive at 50mph

[Rhoward]

I have a 2016 Chevy Tahoe, PPV. I am at about 199400 miles.
I've had the Transmission rebuild recently, and Engine rebuild at 140k

While I drive my Tahoe (everyday), more recently my Tahoe will have a very hard vibration. It's up front and it's only when I'm not accelerating and I'm in the Lower RMPs.

When I press thebgas and climb in speed the vibration goes away. When I coast back to a even speed. The vibration returns. And it comes in waves.

I have a video of the vibration, I don't know if it clear. I'll try to share it.

. This is the video

Hi,
I have a 2016 Chevy Tahoe LTZ also. Pretty much doing the same thing as you described that yours was doing. When driving accelerating between 50 to 70 mph I can feel a vibration come and go. After about about maybe 5 or 10mins it will stop. Did you ever resolve this issue?

Not easy chasing the intermittent issue. Can you check any of the boxes in the above comments? Check away bar bushings and links, ball joints, tie rods, tire wear/balance/psi, exhaust valve, trans fluid/torque converter, U-joints, etc to narrow

Have you installed a cold air intake? Those remove the Helmholtz chamber making pulses back down the intake tract more-pronounced when the truck is in 4-cyl. mode. It's more-evident at slower speeds when wind and tire noise are low. It immediately goes away when you move the throttle and the engine goes onto 8-cyl mode. You can almost feel it on our '12 Caprice 9C1 when it's in 4-cyl mode around 30-35.
