I have a 2005 F150 FX4 w/the 5.4 motor. I have been noticing a knocking noise when i go over bumps but can't figure it out. The same noise occurs when I grab the top of the front right or left wheel and push in and out. The truck will rock back and forth and this re-creates the noise. For some reason the noise sounds like it is coming from the engine bay area. Any help would be greatly appreciated. I can also get a video of it if you would like.
I checked them and there was no play in the lins.. I felt no play in any suspension parts. Like I said before it sounds almost like the sound is coming through the fender wells. I can push up and down on the suspension and no knows. I only get the knock when I am rocking the truck from left to right via the wheels.
checked the coils and they are fine. I also noticed if i have my wheels turned I can rock the truck with no noise. The noise only occurs if the wheels are straight..... This is driving me crazy. Nobody can seem to figure out where the noise is coming from.. :-(
