Guys, can someone point me to any thread which talks about linkage repair especially how to take apart the part where the wiper arm screws in. Both of mine are stuck. There was a small lock pin round one which I was able to take off. After that nothing moves!!! do i need to hammer that thing out? These pivots are now officially welded!!! how do u even move them. You cannot even hold them and hammer. As you can see the frustration - i have beaten them well but no success.
