rear wiper clunk

[dano]

Hey everyone,
My 05 Expy started to experience a clunk from the rear wiper. It only does it at the end of the throw/cycle. About a week ago it did something that its never done, the wiper went about 2/3 the way across the rear window, made a loud clunk then went back to the rest position. The next time I operated the wiper, it traveled the whole distance, but made that clunk, and has been doing that since. ( I'm going to try and take a short video and post it later if I don't come up with an answer in due time). So, if anyone have any ideas as to what could be going on, please let me know.
Thanks for your help, time and suggestions,
dano

Freeway, maybe you should replace the blade once in awhile. Mine works great!

I use it all the time, always works great, and yes, for some reason, I usually have to replace that wiper blade like twice a year, I guess that's because I use it so much.

I use mine every time it rains or snows or the back window is dirty. I usually only run it back and forth a couple of times and then shut it off.
