Can you tell if that's threaded or crimped?
It's not threaded, but not quite crimped either. The nut has a bunch of fingers on it, that provide upward friction on the shaft to not come off. In a few YT videos fixing this, the nut was dislodged somehow, and all you had to do was press it back into place. I've tried getting needle nose pliers and screw drivers under the lip, but no joy. Thinking I'm gonna need to get a pick tool or 2, and pull on the teeth...
This is probably one of those "All or Nothing..." propositions when trying to repair what is more complicated as an optical device than we would expect.
These are my original mirrors, from before I did the power folding mirror mod. They're in great condition, minus one of the heating element tabs I yanked off when removing the mirror glass this morning
Luckily that's not needed down here. What I'm angling at, is taking them apart to put a 2 tone paint job on them. Same as the one I have now, but a better effort on the quality scale. Transfer the tinted lenses and LEDs over and have a better setup.
The PFMs are pretty much dead, and the driver's side has the dreaded twitchy mirror glass, so this could be a cheap mod to satisfy the mod bug. IF I can get the halves apart...
