Haynes and Chiltons manuals are too general and attempt to cover too many models and model years to be completely accurate for any one particular model year. The only manual worth having is the FSM (Factory Service Manual). While it's a lot more expensive, $80-90 or so, it'll quickly pay for itself with specific detailed information and help for your exact model year TJ. You can get the manual from the dealer or on eBay. Caution that some of the "manuals" for sale on eBay are nothing more than a CDROM copy of the FSM that is a PITA to use in the garage. I have the hard copy FSM in my garage and it gets used a lot, my CDROM copy stays upstairs in my den and rarely gets used... and usually only for forum help.
