I also had a loud noise coming from my front right. Popping sound. It was my front brake caliper. You could move my caliper about one inch up and down. I tighten the bolts and the problem was fixed. Check the backside of the brake calipers. The calipers have two bolts on each that might be loose. Have someone walk next to the car and look at the caliper with the car moving slowly. Stop and start,turn the wheels, backup. If it's the caliper being loose you will be able to see it move. Hope this helps.
