Clicking sound from front when suspension unloaded

I am experiencing a clicking sound from the front of my xc60 when I drive over crests which cause the suspension to unload. I’m not sure if anyone else has experienced this but I have changed sway bar links, figured they were cheap and easy, and that hasn’t helped. There are no clicking sounds from the front for normal driving or when turning. Only happens when I go about 30-40mph over small hills and the suspension unloads and wheels are likely at the top of their travel. Maybe it’s the sway bar bushings or more likely the wheel bearings since the clicking sound seems to be synced with wheel rotation.
Any thoughts would be appreciated.
