Or the cv joint bearings? if the boot is split water and dirt get it and wear the bearings out.

You need to jack this up and spin a wheel can you hear any noise?

Any play? have you checked the gearbox oil level, any leaks?

Try cornering fairly hard and see if the noise is louder in one direction, if so a wheel bearing will be the problem If its a wheel bearing the noise will be consistent with road speed, if its the gearbox it would likely be consistent with engine speed.

could be a bearing rumbling, or it could even be just tyre noise, try swapping the tyres front to back and see if the noise goes, it's the first thing i'd try, and it's free.
