A drum rear axle bearing noise changes or goes away when the brakes are applied because the brakes support some of the load on the bearing.
A bearing noise that comes and goes depending on turning left or right is pretty much always a front wheel bearing (and the outer bearing at that) because that bearing is the one that the load varies the most on during cornering.
Just remember this.
Quieter with brakes on is a rear bearing, and changes when corning is a front bearing.
This almost always the case.
