[Vwdiesel] '84 Quantum: wiper linkage adrift again

[Andrew Buc]

~7 months ago I posted about the wiper linkage coming unhooked. Someone 
guessed that the nut had backed off, and this turned out to be true. As 
of a couple of days ago, I find myself again with the wiper motor 
running and the wipers not moving. I haven't dug into it yet (will 
probably do that tomorrow), so at this point I don't know that the same 
thing has happened again. If it has, I'm wondering why it would.

I mentioned to the counter guy at a local fastener store that I'd used 
blue Loctite on the nut last time, and he said I should have used the 
red stuff. I said it was my impression that if I used the red stuff, 
I'd have to apply heat if I ever wanted to get the nut off again, and 
he said that if I used a very small drop of the red stuff, there 
shouldn't be a problem. I'm also thinking of adding an internal tooth 
lockwasher this time. Any thoughts on all this? Thanks.
