A little grease above and below the spring could be your cure.
This is typically caused by a faulty upper bearing binding.

As stated, the vehicle needs to be raised and the suspension needs to be shook down to determine the source of your noise. Tie rods are found by grabbing the wheel at 3 and 9 and firmly shaking back and forth, wheel bearings are found by grabbing at 12 and 6 and shaking up and down. You can sometimes feel the lower ball joint while shaking for tie rod play. Ball joints are confirmed by grabbing 730 and 130 and shaking back and forth. And by 730, I mean the lower front corner of the front wheel. The best way to determine ball joints is to raise the vehicle and load the suspect corner suspension at the lower control arm as close to the wheel as you can get and using a long pry bar and lifting up on the tire while observing the ball joint for movement. Other components such as bushing need to be done with the vehicle raised and a pry bar trying to move the component away from the chassis. Sway bar end links are a common knocking noise that can be mistaken for ball joints and are sometimes a little harder to observe.

As previously stated, check everything till you find the faulty component.
