New Tahoe owner (with problems) Help!
 

I just bought a 2007 Tahoe LT as a second vehicle (for hauling guns/targets to the gun range) and at idle while in park, neutral or any gear there seems to be A rattle or jackhammer sound coming from the front of the motor.

Here is a video... Car has 141k miles


Thoughts?

Thanks for the welcome!

Alternator? Pull the belt and try it again.
