New LSD installed, unexpected behavior.

megalodon · 11-04-2022, 04:44 PM

I just had an MP LSD installed on my 2021 M240i (manual). Right away I noticed a low hum between 50-60 mph. Is this normal for new, non broken-in LSD? Also I have a steep turning driveway. I always go slow up it and never loose traction. After the LSD install my inside tire always skips a little. Any ideas how this can happen? I have done the 20 circles in each direction and have about 50 miles on it. Will theses issues go away with milage?

Installed lsd in my 2019 many months ago now.
That hum certainly doesn’t seem normal.

I reckon the tight turning uphill driveway could cause the inside rear wheel to skip with lsd.
Someone else can correct me if I’m wrong headed about that.
