In this clip we are going to talk about lubrication of the hinge bin on your wiper arm. It is part of the trouble shooting. If you have trouble with your wiper blade not performing correctly and you have replaced the blade, it may be possible that it is not held tight any more. If you pivot your wiper blade up into its lock position, you will see on the inside of it that you have a couple of different components. You have the turn spring and there is a hinge pin and joint mechanism. This hinge pin and joint mechanism is made of actually a couple of different kinds of metal. You have a cast aluminum, a stamped sheet metal and a steel pin. Over time, they may corrode together. If that corrosion resistance exceeds the significant portion of the spring rate on this return spring, the wiper won't be held in proper contact with the windshield. If there is some bug debris or chunks of ice or slush and that wiper blade will skip over it instead of scraping it off, it will leave that big streak all the way up your windshield. In order to avoid that or if you already have that problem, you pretty much just pivot the wiper blade up like I've shown you, take some WD40 or brake oil. I like to use this heavy duty silicone. Give it a little shake, Spray it inside in the crack and work it back and forth. If you can hear, that spring is already beginning to work a little harder. Once you work it back and forth and its got a good snap to it, the job is done.
