2001 Pontiac Montana 6 cyl Front Wheel Drive Automatic 100000 miles
We have a loud noise coming from our minivan - It starts at about 35 mph and goes away at 60mph - it gets really bad when turning to the right. We have already replace the wheel bearings - front and back. My tires on the drivers side are worn on the outer edge and the passenger tires are worn on both edges, but decent in the middle - rear tires are fine. I realize noises are hard to diagnose without hearing them, but with the way it only happens at certain speeds and that it gets worse turning right I thought maybe it would strike up some ideas. Also, if I hit a dip in the road and the noise is worse when the car " bounces" shocks feel fine so don't know if bounce would be a good term. The noise sounds like mud tires until turning right - then it's more like a grinding noise.
What condition are the brakes/rotors? It's possible there is rust on the inside of the brake rotors. Also check sway bar links. It is comon for them to brake then the sway bar can rotate upward and rub on the half shaft.

THanks for the reply - when we changed the bearings we also changed all the brakes as well - also cleaned everything up. I will check the sway bars next.
