Wiper arm linkage bushing FRUSTRATION!

You need to install the bushings into the arms first. You need access to a vise and a socket large enough diameter that the side with the tab can go inside it. Hold the arms with the bushings installed and sticking into the socket. Place it all into a vice and clamp it down until the bushing flattens against the arm, instead of sticking out of them as they currently do. Do the same thing with the other arm. Then, use a pair of vice grips and the same socket to push the arms onto the bracket and pivots.
