My wife (seriously) backed my 2003 Expedition into a mailbox, causing a deep gash in the liftgate. I think my best bet is to replace the liftgate and found several available on eBay. However, I am not sure what it takes to remove the existing liftgate and replace it with a "new"one. Does anyone have a step-by-step guide as to how to do this? Much appreciated!!
