    Ok it was POURING rain today here in Michigan and my wiper pretty much blew apart. How in the heck do I get the arm mechanism off of the shaft? is it tapered or what? I tried for an hour in the pouring rain and finally gave up! It is a 2000 Kenworth, I HATE the wipers anyways but I kind of need them.

    find a truck stop with a shop or just a shop in general of anykind and they can probably help out. Without charging an arm and a leg. If you are a company driver contact breakdown and see what they can tell ya.

    Should have a little lever that pops up right where the assembly connects to the blade... Use a flat head screw driver

    Thanks....it isn't the blade.....it is the arm that the blade goes on. I need to get the arm off of the shaft that it is mounted to.....I thought maybe it was held on by like a set screw.....but there is nothing that I can find....it almost looks like the shaft is tapered....but I tried with ALL my might to get it off there, i just don't want to break more stuff. I am going to call around tomorrow, and see if I can find someone to look at it. Like I replied to Trooper......I am my employers only employee, he is based 2 hours away from me and I will add that he also drives another truck and is TOO busy, he told me to fix it right now. I am calling him in the morning if I still can't figure it out and I'm gonna tell him I am taking it somewhere to get it fixed. He NEEDS to hire a mechanic :)

    I am curious as to why you need to remove the wiper arm. If it is just a bad blade, the blade unclips and slides away from the arm. Unless the spring in the arm is broken, then a blade replacement should take all of 5 minutes (for both sides).

    The arm is usually held on by a small tab. To release that, you pivot the arm away from the windshield like you were going to change a blade, then pull the base. They stick if the arm has never been removed, or hasn't been off in a while...aluminum drive mechanism and steel(pot metal) arm causes bi-metal corrosion.

    The wiper arm has a tiny hole in it near the pivot point at the bottom. Align the hole on both pieces and pin the wiper rigid. This relieves the side load on the stud where the arm goes onto the stud. You might be able to wiggle the arm off if it isn't badly corroded.

    The hole by the pivot at base of arm. It is the size diameter of a medium finish nail.
    Pull the arm away of windshield, put the nail in the hole.
    Pry the base of arm away from the stud. I'm not sure if your truck has a nut that holds wiper arm on the stud that rotates the arm.
    If you can't pry the arm off. I have applied heat to the stud to help break the corrosion. Not much heat, just warm the area a little.
    Also don't forget to disconnect the rubber hose that feeds the washer fluid up the wiper arm. Good luck.
