How to Disconnect the Windshield Wiper Transmission

Video Transcript

In this clip we're going to talk about the proper way to diagnose, remove and replace a faulty windshield wiper motor. In this step we're going to talk about the proper service procedure for disconnecting your wiper transmission from the wiper motor arm itself. The wiper motor transmission, this is the end of the bar, for your trans. What the transmission does is takes the rotation of the motor to the back and forth movement of your wiper arms. In order to remove this, I use a set of large needle nose pliers. What you have is a socket and a ball stud on that, on the wiper motor end. Just squeeze down like so and apply pressure outwards and inwards, just like that. Take and slide the rubber boot off. That's the proper way to remove the wiper transmission ball socket. Don't use just a flat blade screwdriver or pry bar and pry on one side. That may cock the transmission ball socket and damage the fitting. You're going to want to use a device that can pry on both sides evenly, like the needle nose here, just like so. We're going to slide that off. You're also going to not want to attempt removing the nut on the wiper motor stud. You can get the nut off that's not a big deal, however, the elbow is pressed on and made of steal and the splines mount together. The only thing you'll do is waste time by taking the nut off, then having to reinstall it. That's the proper service procedure for disconnecting your transmission from your wiper motor.
