I ask for repair at a professional store and they told me that it is gonna cost 250$ to replace my trackpad because " trackpad is in one piece with the keyboard " for me it doesn't make sense at all , I order tools at IFIXIT to verify my doubt and I was right , trackpad can be replace without changing keyboard , logic , so I order the piece from IFIXIT and with the Guide on line , I made the change without any problem . I save $150 box and had a great time doing the work , I was very proud of me .Thank you Ifixit .
No problem at all , guide very clear , step by step .
Take your time , don't rush , be methodic to be shure you don't get lost with all those tiny pieces .
