Simple task, but much easier if you take the blades off and do it on a table. I didn't see a way to take the rear blade or arm off easily, so I pulled the rubber out in-place.
Blades come off easily, lift the tab and slide the metal blade along the arm toward the pivot point.
Less than two years old, late summer in Michigan, I've never had a wiper fail like this.
Rear wiper rubber, just bent it enough to clear the stop at the end of the wiper blade.
Not much to swapping the rubber, just slide it out. One end of each windshield wiper rubber has a formed notch to hold it in place. Lay the blade down, slide rubber out, lay it next to the new rubber with the notch at the same end. Swap the spring steel exactly as in the original rubber, they have specific curve and notches that need to go the right way. The rear wipers seem to have no notches or curve to the spring, I guess they go together any way.
Dealer ordered these for me, didn't know they would get a bag of each length. Now they have a lifetime supply they said, but I'll be buying a set every two years. Or less if they don't hold up. Under warranty, they would have put aftermarket blades on, no thanks.
