Thanks for the info. I put the XC90 on stands and ran it. The grinding sound is definetely coming from the driver side axle. I really can't tell if it's the bearings or the transmission and I don't see any leakage whatsoever. I won't be able to isolate the noise without removing the axle. So, my next move is to remove the axle and determine what has been damaged...axle bearings, transmission or something else. Hopefully, I won't have to deal with Volvo USA.
Thanks again. I'll keep you all posted!
