Wheel bearing -- front or back?

[gbuchana]

When my 1998 S70 T5 is going around a right hand curve, I'm noticing a bit of a hum. Doesn't seem to be there on left curves and slow driving in the garage around sharp curves doesn't seem to give CV joint noise.

I think I likely have a left-hand wheel bearing going bad.

Is there a way to diagnose front or rear? Is one more likely?

How hard is a wheel bearing replacement? Is there a writeup? I couldn't find much by searching, but I could be blind.

I agree, the fronts are much more prone to failure. A decent writeup is here:
