Hey everybody, we just did a quick video on how to replace your rear wiper blade itself,
but upon inspecting my wiper blade arm, I flipped up this back cap here, and noticed
that the plastic itself had cracked around the brass bushing that's underneath this nut. There's
a lot of corrosion there so I got a new arm assembly off of Amazon- it comes with this cap,
it comes with the arm, and the new blade, so I'm going to show you how to install that. For this
procedure, we have a new wiper arm assembly, a new blade, from a company called Auto Boo on
Amazon. Here's some green painters tape, some PB Blaster (penetrating oil), a rag, and wire brush
for cleaning, a 13mm socket, a little red tube of blue Loctite thread lock, and then an inexpensive
pulling tool in case your wiper arm gets stuck with corrosion. What I'm doing here, is I'm
putting a rag underneath the nut so that I don't get PB Blaster spray all over the car and I'm just
gonna spray it a little bit where the nut meets the threaded post... and let that penetrating oil
seep in between the threads and just give it some time... and as that PB Blaster continues to soak,
I'm going to take our green painters tape roll.... just a little visual ... I'm just going to put
this on the glass right there- it's pretty simple, but it's just an indicator if your window is
really clean and if you don't have a dirt line, you can tell which angle the wiper blade is,
so when you put the new one on you just match up the tip of the blade to where this tape is and
you'll be good to go. Alright, so after letting this sit for probably three or four minutes,
I'm going to take my 13mm socket, put it on there, hold the wiper blade firmly with my other hand...
and start taking this nut off... so it's getting considerably easier which tells me that the
nut did break free so that PB Blaster did its job! Now we've pulled the wiper arm, and it's
still stuck pretty bad... before I try anything else I'm gonna give it a little bit more blaster
I had the penetrating oil sitting there for a long time and it wasn't releasing the bushing
from the post there's a lot of corrosion in there I've heard of people still ripping
the plastic off because it's cracked and then cutting the bushing loose... I'm not
interested in getting metal shavings all around the paint and around this seam... I'm also not
interested in yanking on this thing and putting a lot of axial misalignment on the motor behind
the wiper arm itself. You can save yourself a lot of heartache if you just go I went to
your auto parts store (or Amazon link below)... this puller tool was maybe ten dollars and it's
a really tool. It's a little wonky, so you got to have some patience with it, but basically how
this works is you sneak these two clamps behind it... so make sure it's it's clamped and behind
the actual metal of the bushing itself and not just the plastic.... and then as you screw this in
it will eventually lift this thing off and that's how I got it off!
So these are our three pieces for a wiper arm... it's like the regular OAM brand wiper it snaps
right in, good pivot like that, and then the underside this cap has two pins right there that
go in these holes. Alright- now that functions as the old one did... now let's install it on the
car. Okay, so here is my piece of green painters tape that we had before. I'm going to take this
protective covering off... pop this up... slide that onto the shaft and just have that generally
pointing towards the painters tape where it was. That's the easy part... that's in place. Now,
we're going to put the nut on... This part is pretty straightforward.... before we put our nut
on I have this blue Loctite (number 242)... it's just thread lock, so we're going to put a drop of
that on here... get the new get the nut started... again put one hand in place hold the wiper arm so
we don't put any strain on the motor... and that's it! Close your cap- you're done! So if
