Hey all, i have a 2016 accord 3.5 automatic that s making a helicopter sound and feel under the floor. Ive changed both axles twice bearing and knuckles twice and no change. Anyone had this issue? Im thinking its in the mechanical part of the transmission gears and such. It vibrates and shakes the car also it starts acting up around 30 to 35 mph and gets worse with speedand its Not affected by accelerator release and push and doesnt seem to be affected much by turning either direction. Feels like its in the center of the vehicle. Tires are inmgood,condition and have been balanced twice and is aligned Thanks
