Hello.
How to remove the rear wiper blade section only, not the arm ? ( Separating the wiper from the arm )

 

Solved. Brute force pops out. Replaced the rubber only. All OK.

 

Technically if you're doing it "by the book", on a D2, you need to remove the rear spare tire to pop out the wiper blade from the arm... But I've done a bit of bending and made it work.

The issue with bending the arm slightly ... is... often after you do so, the wiper stops touching the window for its length. Just that slight bend in the plastic wiper arm gets it away from the glass a bit and you'll not be happy with the wiping performance, new blade or not.
