This is a simple procedure that anyone can do as long as you have access to axle stands, ramps, car lift etc.   I'm writing this guide to pull together all the tools needed and steps required to carry this out. This was my first time and I spent more time going back and forth looking for sockets etc than actually doing the work!   Required: torx head screw driver (screws that hold plastic under tray) 14mm socket (bolts that the under tray) 1/2" drive preferred
