My 2004 XC90 2.9 started making a weird screeching/grinding noise and it sounds like it is coming from the drivers side rear. I jacked up the rear of the car and the drivers side rear tire does not spin freely however the passenger side does spin freely and I'm wondering if this is normal? I took the wheel off on the side that I think the noise is coming from, I removed the caliper and the wheel still does not spin freely. The vehicle has about 230K miles and I have replaced the rear wheel hubs once or twice in the past but the symptom was always a loud humming from the wheel which I'm not getting now. These hubs have lasted longer the prior hubs and I'm wondering if their was a new design on these hubs and the symptoms have changed when they are at the end of their life? I'm hoping it's not the rear end...
