The arm keeps falling off the splined shaft. I have hammered the damn thing back together; it works from 3 weeks to 3 minutes. There is not enough room to groove the thing and put a circlip on it, or even to shove a push-nut on it.
The van is old, it's ready for retirement in April, when the sticker expires. But it's winter and I need wipers! Any suggestions to limp it through another 80 days? I have even run a bolt and drilled out the top of the wiper arm, and that didn't work either!
Thanks!
