Rear wheel noise !

Have a 96 grand caravan with right rear noise it is front wheel drive and is louder when making a left turn. Thought it was the wheel bearing but it was not already changed it, also rotated tires.. If anyone has any ideas please help, thank you!:banghead:

On my '96 i had a grinding sound (usually when braking) and it turned out to be a leaking wheel cylinder that was contaminating the brake shoe, retaining dust, and giving me the sound.

please discribe the noise grind,squeal,knocking etc.
