My windshield wipers seem to take too long of a sweep. Both of them slap the bottom hard and tend to even wipe down over the window gasket, and then do the same thing on the upsweep too. Just adjusting the the postion of the wiper arms on the shaft would not help so I'm wondering if the motor has some adjustment for the sweep length. I have not pulled the wiper motor out, but the book does not show anything like an adjustment on it. I did have the arms apart recently to grease the bushings on the wiper shafts and most everything seemed tight.

I do have another 86 I could pull parts from but I don't remember if it had simlar issues or not. I'm just wondering if this is a wear problem or there is some adjustment to be made.
