I have a noise coming from underneath my 07 Silverado 5.3L w/ 110,000 miles on it. Sounds like a bolt rattling around inside an aluminum case(only way I know to describe it). Any suggestions?
May be in the exhaust? check exhaust...
Sounds like the heat sheild for the catalytic converter....
A baffle in muffler or converter has come loose.
