S54 weird sound

[zama]

Hi Gents,

So recently my E46 M3 had been making a weird sound, its like a high pitch coming from the front as I drive, like huhhhhmmmmm.... I can't really explain it. It's most noticeable on the highways, but funny enough when I turn my steering wheel slightly to the right it disappears (tried this while driving on the highway). The sound is audible even when I'm not accelerating, for example, shifting into neutral on the highway and letting it roll.

Any ideas what it could be? Wheel bearing maybe? Belts?

Sounds like wheel bearing. The fact that its a road speed related noise, and when you turn to one way ie right, it off loads that wheel so I suspect it's one of the right hand wheels.
