I am not sure if my water pump or my fan clutch needs repair or replacement.

What is your question?

The cost difference is huge. The fan wobbles and I can hear a clicking sound coming from that area. When Iturn on the ac the sound is just a little louder. I have been told by some that there is minor leaking from water pump. I have been told by others there is no leaking. Timing belt and water pump were replaced 6 years ago and about 60 k miles ago. Visual inspection of timimg belt looks ok. I don't want to replace wp and tb if not necessary as the labor is much higher because of all that has to be removed. Is there a sure fire way to see what's causing that noise?
