I seem to be getting a popping noise right at the end of my stop when braking and then again when accelerating from a complete stop. I replaced the rear U-Joint and had done the brake fitment / adjustment a few weeks ago so maybe I went to loose on the pad adjustment? The sound comes from the rear and seems to be getting louder - hopefully not my rear end differential. What is the best way to diagnose and where should I look first? I appreciate any feedback...
