Sideview Mirror Wobble - 2007 Tourmaster

[proost]

I have a good wobble on the right sideview mirror on my 2007 Tourmaster T40A coach. I want to pop it out and see if I can see what needs adjustment/fixing/tightening but unsure of the process. Would love to figure out the brand or procedure so if anyone has some tips, much appreciated. When I move the mirror right or left to the extreme I see the tabs in there but don't want to break them by lifting them if that's not the correct method.

Thanks a lot!
