My drivers wing mirror has been knocked in the past and now when i drive it is a bit "wobbly". When i have examined it, it is not as sterdy as the passenger side.
Can i make it more sterdy by tightening some screws etc
you can try by removing the triangular plastic cover inside of car at base of mirror,need to prise it off.there will 3 screws see if you can tighten them.if no joy you may have to replace.
