Humor me here…



The paint on my wiper arms has faded/worn away and I decided to take them off, sand blast them and repaint them. The front ones came off in about 30 seconds, but I spent about 15 minutes trying to get the rear one off and I can’t. The nut has been removed and I tried applying tension to the spring and removing all tension from the spring and it won’t come off. Any suggestions would be greatly appreciated.



Spike

lift the wiper arm off the back window and gently rock it back and forth, it is a pretty tight fit.

A little BP Blaster.

A little rock side to side.

It's splined just like the front.



Mine were covered with rust, along with the outer window weather strips.

I took them off.

Wire wheeled them smooth.

Paint with rust inhibiting satin black (semi-flat).
