I bought an 04 4.0 like a month or so ago and I have been working on some of the problems.

When I got it it sounded like this:


I figured out that sounds was that my harmonic balancer is broke here are some pics: (they suck I have to wait till wife comes home from work with cam if better pics are needed)








My question is what years can I get one off of can it be any sohc or would a ohv one work? or does it have to be like 03 or newer?

 

get one of another 04...that is something that i would buy new from ford

 

Yes Buy a New one from ford. Mine was under 200 and they have revised the part so it looks slightly different. And also looks like its made better.

Just curious how many miles does yours have on it. my balancer came apart at 75,0m

 

It nice to see someone else has had this problem but my truck has 156k on it. And I bought it off a guy I don't know how long he was driving it like that.

 

Yeah I was surprised when mine did it. The outer pulley was spinning around the inner part.

 

If anyone is wondering a harmonic balancer from a 4.0 ohv will work on a sohc I got mine off a 99.

 

They are interchangeable. You can get the underdrive for the Mustang 4.0 if you feel like getting a little extra out of it.

 

x2 on that. I wish I had

 

I actually removed mine recently for the blower install.
