its hard to explain but look at pics 7-9 u hold the trigger by the rod with the spring angled a certain way and there is a section on the controller were the spring sits on you have to angle the trigger with the spring to meet up there then u just snap the trigger into the grooves it takes a couple of trys but wen u learn how it works its can be done on the 1st try

u should of never thrown out ur 6 axis thats wat u should use to practice thats wat i used and perfected my way of taking these things apart wen you take the back cover off the ds3 dont touch anything take a look around to see how everything works b4 messing with it u'll have a better idea how to put it back

I will be watching plenty of videos and reading these steps here before I commence with the "operation".

If it is a success I know I will be one happy S.O.B.
