A clicking noise from front wheels.

What is your question?

Yesterday, my car has been replaced front brake drums and pads. After that, I could hear a clicking noise from front wheel at lower speed on bumpy road(never heard before). While I did test-driving with a mechanic, he told me they loosened some part, but another guy come to me and told me that I have to replace a shocker. Please help me, Do I have to replace shocker?
