1997 JGC. Hearing fast clicking noises when rolling

Hi there I have a 1997 Jeep Grand Cherokee, very well taken care of by previous owners. Though what I have noticed is when im maybe going through a drive through and you can hear your car better from the sound bouncing off the walls, well I hear a fast clicking noise when my car is "rolling" or idling. The sometimeswhen im just coasting up a driveway I hear it as well. It seems to be coming from my front pasenger side area but im not sure what it could possibly be im not the smartest with cars. But it will go away when I accelerate. Have any suggestions on what this might be?
