front wheel hub on 2004 Saturn Ion

my 2004 saturn ion makes a very LOUD rumbling noise when driving. The front wheel hub on the driver's side has been replaced but it still makes this unbearable noise, it sounds like it's coming from the front driver's side. What else could be the promblem?

Tires could be cupped out or scalloped (alot of hub bearings have been replaced because of tires) would be the first thing to check.
Does the noise worsen or get better while slowly making a sweeping turn when the noise is there?
