07.5-10 LMM Duramax Powertrain
This might be a dumb question and hopefully this is normal. When I turn my truck off and get out, I can hear a noise thats wierd. It does it 3 or 4 times and it sounds like a spring when you flick it? Kind of like a vibrating or "eehhhhhh" (buzzing sound)? Is this normal and what is it?
