Anyone else experience this? I have a 2011 QX56, just bought it, 93K miles, no accidents, but on the rare occasion I’m exiting the highway via an off ramp while accelerating with a sharp right turn, it makes a kinda loud low growling sound. Any ideas? It sounds like it may be coming from the right tires, but then again, I've made many sharp right turns in many different cars and it's never made that sound.

Sounds like a right-side wheel bearing or drive axle failing.
