Can anyone tell what is causing this noise?
Hi folks, I am getting a humming sound when turning right at speed (60mph+). Started by checking wheel bearing play on the left side. I cannot perceive any play when pulling/pushing at 12 and 6 clock positions. However, when rotating the wheel back and forth there is a clunk sound and cannot see any pad movement causing it. Is this coming from wheel bearing? Thoughts?
Here is a video of the sound: https://youtu.be/R6dqBXvvqZI?si=2eFxIxbdoS1HFTd2 |

Stones in brake shield?

I removed the pads and the wheel speed sensor and it is pretty much confirmed it is wheel bearing, not a pretty noise to say the least:

Thank you, this is exactly what I was looking for. BTW, I am new to the M2, is there a recommended workshop manual to get or reference available in the internet?

I just got it, 2016 and 48k miles. I know the car jumped a curb which bent a suspension link and a wheel and did at least 2 track days.
I highly recommend folks spin the rotors when changing pads to check for noise. There is no perceivable play, yet it is evident the bearing is failing per the video above. |

Also, do not blindly trust the torque specs you find on YouTube, most of them are guesstimates at best. With that said, one exception to this rule is FaRKle! , highly recommend you sub to his channel [1], he does great stuff and the torque specs he provides are from ISTA (or at least it was spot on for all the ones I cross-checked).

Intermittent droning between 60 and 80mph.

Thank you all, I will circle back as soon as I change the bearing to report on what humming/droning noises go away as reference for others since I do not have a baseline (the car already had the bad bearing when I bought it).

Yeah, it’s most likely from those two (+) track days Classic damage from hitting the curbside edge of the track aggressively

Thanks MTown, better to stay out of the curbs at ~$350 each without labor.
I replaced the left side. It was major improvement but I could still hear a faint similar sound. Checked the right side and it is also going bad. Weird that the sound is still when turning right, I read about someone had the same thing on a M235i. Just ordered parts…. again. |

Threads like this are really important. There simply isn't enough info online for items like this going bad. I'm also having to budget for bearings on an 80k mileage OG and wanted to know the exact same things.
The rears look like a royal PITA and the hub design is garbage. BTW, you can add the Hoff to that video list... when you get past the intro. |

Can anyone explain what part numbers and parts are associated or why that even happened? I don't want to mess this job up buying parts I can't use. |

Since you have to replace the bolts also which screw directly on the new hub-bearing, you will be fine buying the latest part number. Here is what I ordered per side:
BMW Wheel Hub Assembly BMW-31207857506 Price: $317.99 QTY: 1 BMW Wheel Bearing and Hub Assembly Bolt BMW-31206872920 Price: $6.79 QTY: 4 BMW Brake Caliper Carrier Mounting Bolt BMW-34106864424 Price: $7.09 QTY: 2 |
