I seem to be plagued by windshield wiper chatter on every vehicle I've ever owned, and my '89 Grand Wagoneer is no exception. My wipers seem to be "loading up" and then springing forward as they wipe, which is putting all sorts of undue stress on the linkage and motor, not to mention streaking the windshield and making awful noises.
Does anyone have wipers that work smoothy, the way they're supposed to? Has anyone successfully fixed chattering wipers on a FSJ? Here's what I've tried so far:
1. Cleaned windshield with clay bar and Bon Ami.
2. Bent windshield wiper arms to apply more spring pressure.
3. Bent windshield wiper arms to achieve proper angle of blade on glass.
4. Removed wiper linkage (worst job ever) and checked for any slop (there was none).
5. Tried different wiper blades.
6. Removed one wiper at a time to see if they chattered individually; they do.
Nothing I've done has improved the wipers' operation. If the windshield is dry, the wipers do not chatter -- they glide smoothly and quietly. As soon as water hits the glass, they jump around all over the place. Oddly, all of the vehicles I've had chattering problems with have used pin-style wiper arms.
My last car, a Cadillac Eldorado, had this problem and I was never able to solve it. I replaced the linkage, arms, blades, and even the windshield and they still chattered.
