    Where does the noise come from? It might be the wiper motor -- if so, a part of the hardware might be broken. If you look under the cowl, you might see the problem.

    But if the noise is elsewhere, and nothing is broken, your switch or wiper motor might need replacing.

    Sounds like your bushings may have rotted off or it just popped off the motor stud.

    I agree - without the linkage attached, the wiper motor sound is very different. It may be nothing more than the white plastic bushings, which are available in the help products. Inexpensive, but it can be a pain working on the linkage on some vehicles.

    You did not indicate specific model Dodge truck nor model year.

    Try this test. Make sure all accessories that generate noise / sound (radio, heater fan, seat belt chime, etc) are turned off. Turn ignition to RUN / ON position but do not start engine. Turn wiper switch to low speed and then high speed. Does the sound change? If YES then the wiper linkage under the cowl area has disconnected from the crank arm on the wiper motor gear reduction. You hear the wiper motor running without any load and it should be noticeable. As others have said there is a plastic bushing / grommet in the linkage arm connection to the wiper motor crank arm.

    I had them go on my 78 Powerwagon and they just went on my 88 aries sw.

    Cheap fix, but not always so easy.

    Somewhat related I replaced a couple bushings and both wiper arms when I replaced the windshield on the 92 Dakota. Dont buy the Dorman replacements. The are soft and the splines strip. I went through two sets in a couple months. Finally I went to the scrapper and got some OEM units and made em purdy.
