i just started noticing tonight when my come to a stop i hear a loud tapping noise coming from my rear end (maybe brakes), maybe u joints? it will sometimes do it when i am driving down the road also but it's the loudest when im stopping. the tapping sounds like metal on metal.... my possible guess is broken brake pads. i havent switched brakes and i have had the truck for 40,000 miles. i am just wanting some opinions before i take it into the dealership.

thanks for your time

 

Just a thought, my wheels are aftermarket and one of the caps was just a little loose but enough to make it sound like something was coming apart. The screws that hold it are barely long enough to tighten, safety feature I guess but I tightened it and it was fixed.
