Question about 2010 Ford F-150 Regular
Posted by Anonymous on
This can be a sound made by "cam phaser" engines that Ford made for 4 or 5 years. Usually the noise quits above 2000 rpm as the phasers limit out in their travel. These engines are very sensitive to the correct weight oil being used and a Ford filter being installed.
The noise has been described as a muffled diesel rattle. Owners report stalling, hesitation, poor acceleration, but most do experience vibrations. What is happening is each bank of cylinders is suppose to be synchronized by the phasers. Imagine if half of the valves are firing several degrees earlier or later than the other half of the engine. Since these adjustments constantly change it makes trouble shooting difficult.
Other areas for rattles are the beads in the catalytic converters which may loosen and float inside the converter or even loose baffles in honeycomb design converters.
I have had terrible noises coming from gravel and rocks trapped in between the heat shields of catalytic converters especially if you travel gravel roads. Since you have "knock sensors" you can get driveability problems from the engine trying to misinterpete the knocks and rattles caused by rocks.

When you say "throughout" that would indicate that it is coming from the rear of the truck..
There could be a number things causing this..
It could be a bad tire or a broken belt on a tire..
A test for this is - roll along at 3 miles per hour.. If you feel a wobble - that is probably a broken belt in a tire..
Or maybe even a bent axle..
It could be a bad universal in the drive shaft..
It could be a broken shock/strut or mount or both..
Best of luck !
