2014 Dodge Ram Hemi 5.7 Vibration Noise

[CoachLL]

Good morning
On my 2014 Dodge Ram 5.7 Hemi 74,000 miles when I start vehicle when engine is cold, I can hear vibration noise through l/f wheel well. Goes away after a minute or so. Just when engine is cold for a while. Don’t think it’s a shield. Any help ? Hopes it not the lower end ?

Check your exhaust manifold heat shield ,it’s also your gasket . If it moves when you grab it ,that is a sign of broken bolts or studs. Search thru this site for exhaust manifold leaks for more information. Search is in upper right of page.
