Sock down the nut tight

Windscreen Wiper Issues and Maintenance

How to Tighten. [Tip from Don Foster] If your wiper arm is loose, remove it (the nut is under the cap), clean off the metal chips from both the arm and the splined shaft, reinstall, and add Loctite Blue to the joint and stud. Then sock down the nut tight. Volvo recommends new nuts, but Loctite allows you to reuse the old ones.

So, how much torque is that?

I had a loose nut on each wiper....how loose you ask...well they didn't work, and semi-trucks on two lane road would re-position wipers when they passed.
