Droning sound from bearings, CVs, brakes or Dif.

I have Suddenly overnight got a droning sound from my Boxster 986 s 2003. Its not the engine because the sound doesn't change if you put the car in neutral and let idle or rev it theres no change.

However if you let the car coast along and turn engine off, you still hear the droning wining sound. Its happened so quickly rather than built up slowly I am wondering if it could be the handbrake shoes gone adrift perhaps.

Any body else had this?

Most likely a wheel bearing on its way out,

I have found that most "droning" sounds coming from Porsches are caused by tire wear, tire faults or alignment. Low profile tires can start to drone long before the tread wear would warrant replacement. Start there before starting mechanical work. I just proved this to myself this week when I replaced a set of tires on a "new" to me 997. Thought is was mechanical for sure, but tires fixed it. How many miles are on your car?
