Hi. I'm Mike from 1AAuto. We've been selling auto parts for over 30 years!
To remove the rear wiper, we start by removing the trim cover. Kind of separate it on the sides and lift straight up. You're basically separating it and pulling it off of those pins out of here. I'll put this aside.
Better use some rust penetrant on here. This bolt is pretty rusty. This nut is pretty rusty. Use a 10 millimeter socket and ratchet, and loosen it. You might have to hold onto the wiper arm. Take that off, put it aside.
Now for this, we might get lucky or we might have to use the puller. We lift up the arm and then rock it back and forth. Sometimes you can wiggle it off. This one doesn't want to come off, so we'll have to get our wiper arm puller.
I’m going to reinstall our nut, just lightly. We've got a wiper arm puller. You can get this from 1A Auto. Just slide it underneath, and then I'll thread it down. The reason why I put the nut on there, I don't want to damage the shaft that this rides on, potentially mushroom it out. Just kind of get it lined up on here, best we can. It's a 3/4 end on this, and I'll tighten this up. It shouldn't take too much force. Pop this off just like that. Remove the puller. Remove the loose nut, and with the arm right off.
Reinstall the wiper arm, we can see the dirt line where it was sitting. Let's get it started. Thread this back on. Tighten it back up. You might have to hold the arm. Once you feel it get tight, that should be fine. You don't want to break it off. Reinstall your cover, just slide straight down. Clips into place. And there you go. It's installed.
