It looks like your passenger side control arm inner ball joint is shot.

Jack both front end up, swing front right tire to full extend left and right, use a flash light careful to examine the rubber cover of the inner ball joint (one that mounted to the brake assembly, not the middle one), you may find it cracked and grease is leaking, this is the indication of a bad ball joint and will give you the clunk when go over sharp bump or road crack.

A loose or bad right sway bar bushing may also contribute to the clunking, check the bushing mounting bracket to make sure it is tight as well.
