I don't know your mechanical skills, but this is not an easy job for a DIY. I strongly suggest to get a manual and study it before you start to work on it. You can find great repair manuals with step-by-step instructions, diagrams, parts locations and other important information here: http://bit.ly/mitchell_repair_manuals_online Or here: http://bit.ly/AllData_Repair_Manuals_Online Zee
