This 2010 Volvo XC70 came to us with about 96K miles, and a loud noise coming from the rear of the vehicle. The noise was noticeable at low and moderate speeds while driving, and sounded like a loud whine or hum depending on vehicle speed.

We’ve seen this before, both on the later model Volvo and the Land Rover LR2 vehicles, and it’s […]
This is a problem we see much more on Saabs than Volvos, in fact in the last 7 years I’ve seen this but 3 times.
