63K on XB 2,hearing a pulsating sound at between 1500-2500 RPM, manual trans, 35 MPH, very slight and have had the wheel bearings, tires,inspected, and noise is still present. Had a driveline boot replaced at 60 K under warranty. I’m running Redline MT 90 for gear oil, smooth as silk shifting, and the car drives well. Any ideas on what this could be ??
Thank you.
