Does a 2005 Edge 4.0 have a harmonic balancer? I have a vibration that I am trying to pinpoint and the symptoms of a bad balancer seems logical in my case. If not it may be a bad mount? Or seperate pulley problem? This vibration is present at all times but REALLY is evident when i hit 65 mph. I've ruled out tire issues, so its gotta be engine or suspension.

 

For the most part , all engines have a harmonic balancer on the front of the crankshaft.
If the vibration is generally when you are moving , I suggest removing the driveshaft and checking for a bound up u-joint.
If it is mainly at speed , check the shaft for a missing balance weight. They are usually welded toward one end of the driveshaft on the outside, they have been known to come off.

 

I think there is a TSB on this i'll look into it.

 

if your harmonic balancer has failed, the truck wont start. Atleast this is what happened to me. 500$ later, it worked -.-
