Vibrating Wing Mirror

[Northencampervan]

My drivers side wing mirror vibrates to the point where I can barely use it on the Motorway.

I've seen a few things saying it could be the glass needs regluing, and a few saying the arm which attaches it to the car.

Obviously I need to dismantle it, but do I need to be aware of anything in particular, DAB Radio, nasty bolts, a quick fix so I shouldn't bother dismantling it!

The glass isn’t glued.
There are 3 screws securing the mirror to the door, accessible with the door open, easily checked.
The screws for the hollow pivot are only accessible with the mirror shell removed.
If I were stripping the mirror I’d do it off the van, you’ll find the procedure on the forum with the Search function.
