Clicking noise when driving

More then likely this is a brake caliper that is clicking and when you apply the brakes it puts tension on the caliper and it stops clicking.

I would remove the caliper and inspect it for being loose or binding. I am pretty sure you will find your issue in doing this. If you want to, you can lift the vehicle and spin the front tires in the air and see if you can pinpoint it assuming you can get it spinning fast enough. If not, I would just remove the calipers and inspect it.

Let me know if you have questions. Thanks
