Re: Rattling/Tinging Noise - '99 Explorer
Check all the bolts.
I had a bad rattling sound that got worse on my Sprinter 3500 the other day! Turned out to be a loose/stripped bolt. There were 4 (two fixed and two adjustable), and this one bolt in particular was replaced previously as there were NO washers installed in it to absorb vibration so it was only a matter of time before it became a problem.
As you removed the belt, that rules out some of the accessory drives as well as the idler pulley as the source of the noise. If you can, get under the vehicle and check EVERYTHING you can see, touch, etc to make sure nothings rubbing against something it shouldn't.
