Please, don't order just any brand.
FAG bearing is the OE and is the one that lasts.

The Volvo workshop way and also my way to do it is:
Remove wheel, undo tie rod, undo driveshaft bolt, remove brake calipper and disk, put penetrating oil between the hub and spindle, separate ball joint from the control arm by pulling the control arm down with a ratchet strap attached to the other side control arm (both sides close to ball joint), separate the driveshaft, undo the hub bolts a few turns, knock the bolts from the back and see if hub starts coming out, just keep undoing the bolts and knocking the hub out and it should come.

Fairly simple job, no special tools.
