My 2010 5.4 Crew 32k miles has developed a "baby rattle" sound in the front end. Happens sporadic around 40-50 under acceleration only. Take your foot off the gas & it stops. Seems to happen after it's sat overnight most of the time. Haven't ran it in to Ford yet. Any ideas boys?

 

Mine dose the same thing but also there's a lot of other things messed up on mine. But dose you tranny clunck at low speeds like in a parking lot?

 

It has thumped coming to a stop then taking off again like it's not engaged

 

Same. Also dose it shift kinda hard?
