Balance shaft or not??

[Marty'70]

Ok, so I have an 04 with a 4.0 that had over 160,000 on it. The timing chains rattled then and still do so it's time to do the nasty. My question is as I was looking for parts , some places (Rock Auto) has an option for with balance shaft or without. Do I have one or not? I have never dove into a 4.0 other than simple things like hoses belts and thermostat. Also was wondering if someone had a step by step instructions so I could look at before doing the old " well shit I didn't have to do that!" Like most other jobs you do for the first time as a learning curve. Any suggestions for other things to do while the engine is out would be cool as well. Thanks guys. This place is awesome for info.

Buy the kit for the one with a balance shaft. The price difference is usually insignificant, but the only sure way I have found to know is to pull the front cover off.

Also be aware of several other things.

1) The engine pretty much has to come out to do the rear chain, which is probably the one giving you trouble.

2) You will need external torx sockets.

3) Some of the bolts, particularly the ones at the rear of the engine, are left-handed thread.

4) The cams are not keyed. You will need special holding and alignment tools to do the job correctly.

For what it's worth, there's an active thread over at Explorer Forum where users are testing out manual chain tensioners on the SOHC. Might be worth a look.

Wasn't aware of the tools required. I do have torx sockets both internal and external, but where do I get the timing tools?

Is the 4.0l SOHC timing chain tool kit, look on craigslist or ebay for "used" kits, people buy and sell these because they are a use once type item unless you are a full time shop mechanic

You can also check local tool rental places, there is a larger kit that has the alignment tools for multiple Ford engines, I think its the OTC 6690

The description of this says for 97-02? Is this the right one? I don't think they changed anything.
