Shake and rattling mirrors on a 2020 Freightliner

If the glass is moving I have seen gladhand rubbers slid in between the glass and the housing. I thought it was slick.

obviously not a permanent fix but hey if it works…….

 

Check the "break away" if it's lose you'll need to replace it

 

I could be mistaken, but I don’t think you can replace just the glass or “insides” on that truck. I had one at Ozark with shakey mirror and the entire assembly had to be replaced. Thats another thing that sucks about newer trucks and cars. Stuff is made as an assembly. Can’t just rebuild or replace parts like older stuff. Also makes it much more expensive to repair a small issue.

 

This is what the one on my prostar looks like, your should be simular...
It's the end of the brace that pops lose to allow it to move if hit...

 

Cascadia is totally different.

 

There is a break away funtion in that arm so to speak.
