We own a 2010 FFH. We purchased it used in 2012 and it's worked great since then. Only thing we have done so far are replace the under the hood battery and the spark plugs (twice), cabin filter, and of course engine oil when it tells us to.
We initially the thought the vibration was coming from a bad spark plug, so we ordered new MotorCraft ones and the vibration is still present with the ICE is running at low RPM and up to about 60mph you can feel it. We also thought bad gas or something, but we have been through a full tank and vibration issue still persists.
A couple of days ago at very low speed when the brakes are applied, I hear what sounds like a rubber hose rubbing against something on the passenger side engine compartment. We are thinking engine mount on the passenger side, but not sure how to check it.
Anyone have any ideas on how to check if the motor mount is bad or maybe what else would cause this issue. There are no lights coming on in the dash and the engine seems to be running fine, sound wise, it's just the vibration from the engine that causes the rearview mirror to vibrate and whatever is loose in the dashboard area, mainly that compartment door on top of the dash.
Ideas or thoughts?
