Pull the wiper insert out past  
the stopper on the wiper blade,

is completely removed.  
Lightly grasp between the claws of  
the wiper blade to allow the wiper  
insert to lift up, making it easier to  
remove.

Remove the 2 metal plates from  
the old wiper insert and install  
them to the replacement wiper  
insert.

Insert the wiper insert starting from the claw at the center of the  
wiper blade. Pass the wiper insert through the 3 claws so that it  
sticks out from the stopper, and then pass the wiper insert through  
the final remaining claw.  
Applying a small amount of washer fluid to the wiper insert can make it  
easier to insert the claws into the grooves.
