What's missing from under both of my wipers??

 

Looks just like my '12 in the same area. I don't think anything is missing; just left ugly.

 

Actually, i 'think' they changed them
because the 05~09s were super tight;
my 2006 squeeks when its even a little dry
& my bolts are loose as possible;
they just added more slack
if they are tight
& work properly, its ok

but check other 09+ cause i'm not 100% sure
