Alfa 159 jtdm droning and vibration.
I have trawled through as many threads as I can. But alas no answers.
So I'll start my own and beg for your wisdom and mercy.
My wife has been using my 159 2.4 sport wagon whilst I was away with work. And I've come home to discover I now have a road speed related drone/ humming sound from the front along with a faint high frequency vibration through the steering (not wheel balance).
So I have been investigating with the car up on stands wheels off.
In 6 gear at idle you can clearly hear the noise and feel it transmitting through the track rod. So I disconnected the ball joint from the upright. And it's isolated to either cv joint or wheel bearing. But I've never heard a bearing make such a noise and not change with loading or unloading that wheel. But also I've never heard a cv joint make a high frequency vibration either.
Any opinions or similar experiences out there??
