I have a 2010 FX4 SPCREW with the standard 5.4 and I hear this weird strange clapping sound, not too loud but noticeable. Follows the rev of the truck, the higher the rpm, the faster the clapping. The truck has under 5000km (Yes I am Canadian) anyone knows what could cause this?

And I am also looking to find some tail light guards but having a hard time to find some for the 2010, looking for the metal ones, would match my Westin grill nice. Anyone knows where I could find them?

Thx!

 

Not sure about the noise. The truck should still be well within warranty, jsut take it to the dealer and explain it to them.

Westin makes a set of matching Tail Light guards for the 2009-2010 trucks. Westin Tail Light Guards

 

Is it a clap or a ticking noise? I know the modular motors have an injector tick that is normal, but I have also heard about the cam phaser making a similar noise. Let the dealer ceck it out.
