Rear Wiper Arm replacement

[auggafj80]

Not sure if anyone has replaced the whole rear wiper arm or not. I looked and didn't see any posts. Just want to share my experience. Wanted to replace mine purely for cosmetic reasons, it was looking quite faded on my 08LC, and maybe a little limp! Looks straight forward, take the 10mm nut off, pull the wiper arm off, new one on, done. Not so fast. The inner portion of the wiper arm is metal and it had seized up pretty well around the center post (see photo, showing new arm on) After wd40 didn't help ended up doing some careful drilling of plastic / metal to get it loose. Also replaced the rubber grommet and got a fresh nut.

Put some never seize on it too. I will say this could have ended badly with a drill near glass, just before xmas. But if you're not living on the edge....

Be careful with that rear glass. It's a $1200+ part. Don't ask me how I know.

WD-40 is not really intended as a rust/corrosion penetrant. Rust Buster is much better, best I've found is Kroil. Might have made the difference for ya...

Would this have helped?

I use this on my 80 windshield wiper arms. Makes an impossible job possible.

Likely but I didn't have one of those tools and was in a hurry. I just went into destruct mode. Good to note for others attempting this.
