Here's a thread on another forum that details how to replace the cam sync. There are two methods to do this, this one is the harder one, but I believe it's the more detailed and exact one. Part one is the simpler one, and may be better for you. However, I can't find the link for it.

Here's a pic of the location. This pic shows the back of the motor.




As far as cost from Ford goes, it tends to be in a steep range, from $150-$210 for the CPS and the Cam Sync. This is well worth it as when the cam sync fails, the oil pump stops spinning, the truck loses oil pressure, and the motor goes boom.
