SHYNE - it is a do it yourself job if you have the ramps, the right socket and a torque wrench. Make sure you remove the fill plug first and make dog gone sure that it is raised securely! You do not want to put your body underneath and be torquing something that could possible roll off of a ramp or fall off of a jackstand. Take a long hard look at it and make sure it is SAFE to crawl under before crawling underneath.
