Hello. My truck has recently started doing this and my dads 2000 does the same thing. The rubber flaps that go over the arms on the hood (right in front of the windshield) on both sides of the truck "rattle" at speeds over 50mph. Do these flaps come untucked from inside there or do they get old and start flapping in the wind? I dont remember this problem happening earlier. Are replacements the answer? I dont know the exact name for these things either...I tried doing a search but it doesnt help if you dont know what they're called for sure. Can anyone help?
