How do you remove a windshild arm on a 1992 Mitsubishi truck?

To remove the windshield wiper arm on a 1992 Mitsubishi truck, start by lifting the wiper arm away from the windshield. Look for a small retaining nut at the base of the arm and use a socket wrench to loosen and remove it. Once the nut is removed, gently wiggle the wiper arm to detach it from the splined shaft, being cautious not to damage the windshield. If necessary, use a wiper arm puller for added leverage.
