Buy the Haynes. A disappointment the new Hayes/Chilton Repair manuals are from Haynes publishing group (compared to their older guides and detailed content). My wife bought both for me as a Christmas gift and she thought they were different. I have used many of the Haynes and Chilton repair guides over the years from older cars I have had and the new ones are pretty poorly written when it comes to actual repair guidance to specifics and content. In regards to content, the Chilton version "published by Haynes Publishing group" is basically larger print and a different font of the Haynes guide. On top of that it appears that the Chilton guide uses photocopies of the Haynes photos. You pay $5.00 more for Chilton. As for repair info, on removing a rear disc on a 4x4 F150, it says to see illustration for removal. The illustrations show you nothing but a retaining clip some of the models may have. Nothing in regards to whether the disc pulls off or if stuck on how to remove. That is not a hard repair but the info on 4x4 suspension and other more detailed information is vague in regards to instruction. Haynes does a good job in engine tear down but how often are home mechanics doing that. It is when you're trying to do a brake job and you have problems that explanation and clear instruction would be most helpful. There are many other examples but I think if your looking for very detailed repair manual with complete break down of parts, get the book from Ford directly which may cost over $100 but worth its cost. If you're a novice home mechanic and want to change your oil, fix an internal wiring problem, or replace a water pump this will give you reference if you're knowledgeable in auto repair, so get the Haynes manual and if you want to spend $5 more and have poor eyesight buy the Chilton guide. Not to say this is a bad guide to get but the older guides from Haynes publishing they were pretty detailed for the value.
