Query: haynes lightweight information

I found the information for a 1988 Jeep Cherokee to be vague, superficial, and many times, incorrect. This might be due to production changes in the 1988 year. In looking for information on automatic transmissions, ignition system, engine control computer, or transfer case dissasembly or repair, the book says that this is beyond the home mechanic. Well, few other repairs even require a book for anyone with reasonable experience. I believe they are copping out. It was not worth reading.
