WTF is this weird rubbing noise?
I have an 08 E90. 6MT. EDC. All stock.
When turning left or right at very slow speeds, 2MPH - 15MPH, the car makes a very unrecognizable (to me at least) rubbing noise in the rear. Different speeds yield different sounds. Sounds worse at lower speeds. Turn up your speakers or listen closely. There are no spacers, no wheel play, and tire pressure is good. Going back through the maintenance records, on April 15, 2017, the driveshaft was replaced due the previous owner stating "a clunking sound when turning right only." BMW stated "Driveshaft is faulty. Found U-joints in driveshaft were very loose and damaged yoke of driveshaft. Replaced Driveshaft. Noise is gone after driving car." Any one experience this before or have any ideas what this could be ? Any help is appreciated |

It's hard to tell. I would have the differential looked at, although this will typically make more noise n a turn if there are issues.

Jeremy, agree with above on the diff. I have exactly the same when slow speed. Goes away after some driving/warming up though. FWIW I had the fluid changed at 19k (54k now), same noise before/after.
I view it as a good sign that the diff works, wouldn't add more FM just to make it silence but loosing lock up effect. Cheers |

I've been so out of the car game that i didn't even think of the differential. I'll get it flushed and refilled and see what happens. Thanks everyone. |

Limited slip noise. FM comes with a price. You can add some and eliminate noise but the more you add the more slippage it may induce. Mine makes a little noise too when cold because I didn't add any friction modifier when I changed the oil.
