The right side mirror on my 97 f150 kind of sticks a little when I adjust it. Are there some gears or something that I could use a dry lubricant on, before I replace it? thanks

 

There are cable pulls that move the mirror.
Yes you could use spray lube to try to get to the pivot points.
Move the mirror by hand so there is space between the housing and the glass.
Work the system till it's free, then hand adjust the mirror position until it able to move full range in all directions.
The mirror will slip the gears to make the adjustments in both directions.
They are a plastic type composition.
The glass is replaceable.
Good luck.
