Labor rate shows it is a 7.5 hour job for professional mechanic with axcess to prper tools. Autozone have some popular workshop manuals for free on line once you register (for free) on their website is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You get a one year subscription to year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual. or try and get an online repair manual subscription.
