Hello all,

BLUF: I need some help identifying a grinding sounds when i'm above 50 mph and only when off the gas, when I am even slightly accelerating or just slight pushing on the gas pedal sound goes away.

Car is 2011 5.0
Basically car has full suspension and it all started after the installation.
Watts link went in first as my first ever suspension mod everything...

Needs some help and idea identifying a possible issue/noise. VIDEO attached.
