Loose Rearview Mirror
 

The arm on my rearview does not seem to be fully seated in the mounting plate. While it doesn't fall down, it does shake a lot when the car hits a bump.

I tried removing and re-installing but can't get it any better. Is there a trick to snapping this all the way into the mounting plate?

Also, the mirror swivels a little too easily on the arm. Is there a way to tighten this?

Two ideas:


1. I've not looked on my Jaguar, but past cars had a set screw. Just tighten and that part is snug. The female side of the ball and socket has worn. Gently tap it down tighter. A little peen process


2. Get a better one from David Boger at Everydayxj.com.


Wiggly mirrors are a distraction


Carl

wiggly anything is a distraction! :)

there is a metal bracket behind the black cover, it could be broken as it is designed to break in accidents.

The factory service manual describes whacking the end closest to you (rear) with a rubber mallet to seat it into its recess. I just can't see my self whacking anything hard enough with a rubber mallet so close to the brand new windshield that I just installed. Any thoughts?

Blu-tack

Not sure what anjum meant about blu-tack, but I figured out an ingenious (I think) way to install the rear view mirror that does not involve whacking it with a rubber mallet.

Find a relatively small Allen wrench and a matching diameter drill bit.
Using the small(ish) bit, drill a hole in the mirror base approximately 23mm back from the rear (end closest to you).
Depress the spring loaded keeper with a flat screw driver or other implement (wear gloves in case your tool slips).
Insert the Allen wrench into the hole and all the way through, detaining the keeper.
Offer the mirror up to the base that is screwed to your roof and simply pull out the Allen wrench!!
I figure using the Allen wrench for this is good because it is hardened, though I suppose you could use the drill bit, though bits tend to be brittle.
And yes, you'll have a very small hole in your mirror base, but it's a whole lot better than risking cracking the windshield!!
