FYI, while you are lubing and maintaining your wiper system, you might want to put a little grease on the spring detent that hold the wiper arm off the window. This is the detent that allows the wiper to remain off the window while cleaning the windshield at a gas station. My 87 got very stiff and I was afraid I would break or bend something when pressing the wiper back against the window. A little lithium or silicon grease works great and will last for another 10 years!
