How to remove wiper arm?

[IndianaTravis]

The plastic piece under the wiper arm on the driver's side of my car is warped a bit and no longer seals against the windshield.

I'd like to replace it (it isn't terribly expensive) but it seems I need a 'special tool' to remove the wiper arm from the splined shaft.

Has anyone found a way to do this without having the special tool?

IIRC, mine is just an 8 or 13mm bolt. Pop the black cap off with a screwdriver then turn the bolt.

I don't remember doing anything special when I was adjusting the sweep.

The bolt is 13mm, is under black plastic cap at the end of wiper arm, until you take off it push the wiper arm close to the hole in direction to the front glass and the arm go off easy, to install (i recomended that mark the wiper position with tape or some other thing nin the glass)put the wiper arm in the marks , when you thig the bolt the arm go to position without any problem. To take off the plastic cover under the wiper is necesary take off the two wipers arms. I paint mine, look super cool.I hope you understand my write because i'm spanish...

Also buy replacement fasteners since the old ones may break and be discolored.
