I'm sorry that none of these jack holes took the time to even let you know or even have the decency to give you a courtesy reply.. I realized alot of the guys on this forum is kind of just like that, so I might move to another forum. Anyway, From what I know the mirros are suppose to be seal tight from the factory. You have to take it to the dealer to get the original part, it's not something you can use locktite and other crap with.
I hope this helped some what. Mine is getting alittle loose too on the left side, So i have to take it to the dealer.
