Vibration at 55 to 70 mph

[Lukasguy]

Hi peoples

I've got an annoying vibration when when driving between about 55 mph to 70 mph. At speeds above this the vibration goes away and the car drives nicely.

I can feel the vibration in the car itself, but also a little bit in the steering wheel.

At first I thought it were my wheels so I had them all balanced. Vibration is still there.
Next I noticed my brakes needed replacing so I did that as well, vibration still there.
I also replaced all 3 motor mounts which also didn't help in this case.

My next suspect would be my cv axles because I've read that they can also cause vibration during this speed but this would mostly be during acceleration, which is not the case with me because the car keeps vibrating even when I let go of the gas. Could it still be these? I also sometimes notice a faint ticking noise when turning a small bit on the highway.

I've also had the 2 front wheel bearings replaced in the beginning of the year so these are still good.

The car in question is a C30 1.6D2 from 2011.

Thanks everyone!
