A humming or howling can be cause by a dry, worn out wheel bearing. Also tires that aren't worn evenly across the contact surface of the tire will cause a wheel bearing like noise.

on this type of vehichle, you have two axles in the front; one going to each side. Chances are that the boot at the axle joint was torn and that is why you are having problem. In teh past people used to replace the boot, this day and age its actually cheaper to replace the axle. So you would need to replace that side of the axle (the half shaft).

You must replace wheel bearings in pairs to avoid loading the old bearing and, in time ruining your new bearing hub it is possible that you have already damaged the new hub

Could be either a loose belt or you are low on power steering fluid,or the power steering pump could just be worn out.

When you turn right - you're taking weight off the right wheel.
If the noise dissipates - the passenger side wheel bearing is most likely to blame.
Thanks
