Go to
www.helm.com to order the factory Service manual if you can't find anything else. They cost $$$ but have pinpoint test and component info that can save you from replacing parts that aren't bad. Also have reference to ford part #s and very detailed breakdowns on part removal, inspection and replacement. They also have it in CD format if you prefer.
