Default Wiper Arm, a pain in the neck

So, the Bentley says "it may be necessary to gently rock back and forth to loosen arm from shaft." Well I rock it...even to the point of slight abuse and still won't budge. Any other hint anyone can offer? I am replacing the cowl cover and have unscrewed all nuts leaving it like that. Every now and then I turn the wiper on hoping to loosen...ever sprayed lubricant.

I had this exact problem the other week when I replaced my cowl, one arm came off the other wouldn't budge. Here's what i did.
  1. Cut the old cowl off, this gives you better access to the underside of the arm.
  2. Spray penetrating lubricant from the top and the bottom.
  3. Create a constant pressure from the bottom, I used three open ended spanners and stacked them up and really jammed them between the arm and the the (other) arm it's connected to. I think I used three spanners but whatever you have.
  4. Walk away for two hours.
  5. Come back and try again, mine popped right off.

Of course if you have a puller then just use that!

You used a wiper arm puller or 2 arm jaw?

The arm is spring loaded so you have to wiggle the arm back and forth(you may find putting the wipers up so the spring doesn't constantly interfere) to find that spot where it doesn't resist against the splines. But if all else fails you can pick up a wiper arm/2 jaw puller as previously stated.

Actually it is really easy once you understand where to rock it from. No sprays or nonsense required.

See the pivot point where the arm lifts up from the glass? Push down in the center there, pull up, push down, pull up. Only takes a few goes and it will always release for me. Leverage is key here and working smart will yield quick and easy results.

^ BMW has a special tool specifically because your method doesn't work in every case. Don't be so absolute.

Says who? I've never had an issue on any E36 I've needed to remove a wiper on.

You also live in the land where there isn't salt everywhere for 5 months out of the year.

That being said just keep on wiggling, it'll come off.

I've had the displeasure of dealing with cars from rust belts.

I never stated my method as an absolute either. It was directed at Ralston who typically has success with most guidance I have offered him.

OP PM me if you can't get them off. Another forum member and I had to resort to extreme measures to get mine off, and it's been a CA car all its life. We managed to get them off but in my case it was much more than finding the correct leverage point.
