I am getting a high pitch whining noise that i notice around 60mph and it gets more noticeable at higher speeds. The pitch changes at speed, and when I lift the throttle, it disappears. I suspect it may be a rear end ring and pinion that has developed a wear pattern that makes noise with torque from throttle and disappears without the torque. Seems to make noise in 5th and 6th gears. Thoughts? Anyone else get this noise?

I had an 1st gen RX7 that made similar noise that was the ring and pinion wear, so that was where my speculation came from. Thanks
