Update 9/13/19*** problem solved!!!

The rumbling noise I was getting was not normal. The drive shaft bearing housing was installed upside down, throwing the alignment of the driveshaft off by a few millimeters causing that rumbling noise.

Finally got the m performance LSD installed on my 2014 m235i.
LSD had fluid that leaked onto the box it came in. Shop cleaned it up and didn't really see any issues so they went ahead with install. After install fluid was added and the 20 figure 8s at idle speed in either direction were completed. Then per BMW recommendation I've been taking it easy on the car and plan to do so for the first 500 miles.

Unfortunately I'm getting a chatter or vibration that is seemingly coming from the LSD only on acceleration in 1st gear from 2.5k-3k rpms on heavier acceleration (talking about when the car is going straight or turning).

Any thoughts on what this could be? Normal during break in? Should I change the fluid?

Please help ripping out my hair over here
