Is there anybody experiencing a knocking noise on Tesla SDU?
This only happens when in reverse and foot off the accelerator - slow down. The motor is still on the test bench - no cooling. Youtube video link
There's a pump in there that lubes in drive, not reverse. That's the only thing I can think of that's different other than a parking pawl, which I don't think Tesla has. Not having axle stubs in there might be what's making the sound in the diff. All guessing - you gotta troubleshoot it.
