if you have a manual, and you are well organised, you should do fine. ohh you will also need space. Do you have tools. not just your basics!!! you know sometimes it just easier to pay someone to do it. main reason, the problems that can arise!!! its an easy job that can become a pain in the ass in the blink of an eye. the one thing you want to rember is to be and stay as clean as possible, your tools also. good luck!!!
