hey man as slip said rears r a quick job the fronts on the other hand r a little bit harder but if you have a vice & a f**king BIG shifter your should be right as the fronts are an insert not a mcpherson strut, I am assuming that u know how to get the spring off here so once u have the bearing cap off & the spring off take the bump stop off & there should be a large hex nut on the top of the shock body undo it & nemove the old insert clean any oil out if your old inserts have been leaking & fit the new one's
Make sure you do the Nut up F/T as they can come undone over time & just do the reverse of taking it apart hope that helps mate
