I don't know what year your F150 is, but the Mustang 4.6L (3V) had two piece plugs that can come apart upon removal up through some time in late 2008. Do the 4.6's in the trucks have this issue as well?
No jack, it was fully unloaded.

That year truck should have a 4.6L 2V which does not have the plugs that break in the head.
Okay, Ill go with the upper balljoints being bad, with this one worse than the other side.
And yeah, Romeo 4.6L 2V is whats in it. I happen to have a spare one sitting from my '04 CV in case it blows too.
