Mine WILL do it on every slow sharp turn. Very easy to reproduce ANYWHERE.

Correct. That's what I posted.

limited slip and tires was my 1st thought

Yea, Im pretty sure its the diff. Mine does it when I move the car after being parked.

It's the differential just doing it's thing. You are only noticing it on slow sharp turns because that's when you have the greatest difference in relative speed between the inside and outside rear tires (and also, a lack of wind and road noise to mask it). A slight "rumble" is fine, if it changes to "WTF is that ungodly clunking?" then you might have a problem... or just a cam and pawl diff.

Thank you for the feedback... It is comforting to hear, but strange no one else is really bringing this up. I have never felt this in any of my previous cars, a few of which had LSD

My 2001 IS300 did this. Was an automatic too.
