Went back and re-read what I typed. Didn't make sense to me either. Yeah...what HeadGuess said. Basically the wind pushes on the backside of the mirror and causes it to angle so far down that it's useless. Is there a way to tighten that up so it'll stay put? I looked at that ball joint and didn't see any adjustments externally. Maybe something inside the mirror housing?Thought I'd ask before digging into something for no reason.
I decided to take the mirror out of the housing to see what was inside and I'm glad I did. The joint is held together with a spring over a threaded bolt and a 10mm nut to adjust the spring load. A simple twist and I'm good to go!
The black rubber trim around the mirror is actually a "case" (per say) that not only surrounds the mirror edge but also covers the entire back. This entire assembly can be easily removed by inserting a thin flat blade (butter knife) between the rubber case and the metal housing and slowly moving around the edge to pry the rubber case house. To reinsert, press the butter knife in the opposite direction to flex the housing outward while pressing the mirror/case assembly back in.I did this to both my mirrors and never felt like the mirror glass was at risk of breaking.
