Power mirrors on 89-91 subs and blazers

[3car]

I have noticed that everyone of these mirriors i've seen is loose and sloppy(never good) at the pivot.
Has anyone ever taken one apart and tried to tighten it up? My mirrors look great, but I dont appreciate the vibrating around too much.

it should be 90 or 91 only for the mirrors. and its die cast pot aluminum in the inside. mine was fine on my 96 truck same style. and i hit it one day by axident and it fell right off. lucky me i had a spare set off a nother truck.

there are three screws on the bottom side that attach the mirror head to mirror mount try and tighten those.
