Frank, Is it common to hear a knock in the lower end of a 2009 F150 4.6 ???? Think I got one here..... @Tooljunkie

They all kinda knock.dont know if flywheels crack on them.
Check your belt.and crank end play. If its a high miler,10w30.

Took your suggestion and bypassed the ferrite coil. Soldered the four strands and bridged the circuit.
