I'm not sure how you can test to find out which component which is attached to your belt is squeaking, but I had an issue where my alternator was making a squeaking sound, and a friend of mine had an issue where it was his A/C compressor which was squeaking. If your water pump is fairly old and you plan on keeping your jeep for awhile longer there is no harm in replacing the water pump, it will fail eventually anyway.
