Hello all, So just recently i have been hearing a click or pop sound when braking to a stop. It clicks once when coming to the stop but does not click or anything when giving it gas. Occurs at every stop. Im running stock 44 in rear, with RE long arm and track bar. Checked all bolts for suspension and it doesnt seem like it is the cause. Jeep drives fine and brakes fine, just have no clue what the clicking is. I searched and found a lot on multiple clicking and popping but nothing with a single click. Any ideas??
