Clicking, especially while turning, is often symptomatic of
a failing CV-joint. One thing you can do is get under the
car and inspect the CV boot. If torn, that's more evidence
the CV-joint has seen an ingress of dirt and water and so
has likely been damaged.

http://www.aa1car.com/library/2004/bf100434.htm is a good
article on this. It talks about a clunk being a symptom,
too. Googling for {"CV-joint" symptoms click clunk} turns up
more consumer articles.

Keep checking back. I haven't actually repaired a CV-joint
but am just aware of the symptoms and inspect my CV-boots
regularly.

I do not suspect the wheels but just to eliminate them: Is
the tire wear even? Are the tires kept to the correct
inflation pressure? Have the wheels been balanced fairly
recently?
