You put the car somewhere quite, have the car jacked up, crawl underneath and listen for the leak. Also have a spray bottle of dish soap & water mixture and spray onto anything that involves the air. Bubbles will form around the leak.

Mix up a spray bottle with 20% Dawn dish liquid and water. Spray it on all the suspension lines, connections and parts. Any dish soap will work, but I found Dawn is particularly good at locating small leaks. Small leaks will create bubbles. The mix is called snoop and mechanics working on compressed air and other compressed gas lines have used it for well over a 100 years to find leaks. It is the best way to do so if a visual shows you nothing.
