2001 Pontiac Montana Loud noise - already replaced wheel be

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.

Thanks!
