Power folding side mirrors not extending all the way

Just like the title says.

The mirrors are not extending all the way, seems to stop short. Not by much, but some. Hasn't been a problem for me but now that my daughter is driving(Good Lord!)she has a hard time adjusting them to her liking.
Anyone have any experience with this? 2008 Tundra Limited 4WD, heated glass with turn signal, power folding.

Thank you in advance for any helpful advice, Henrik

 

I had to lubricate mine when I had them because sometimes they would not unfold completely.

 

Thanks for quick response. Did you do any disassembly to lubricate or just spray lubricant of choice around the pivoting area?

I just very carefully Sprayed Chain Lubricant in all the pivoting areas and Hand worked them back -N- forth at same time did not take apart I used Chain Lubricant because it thickens into a light grease VS using something like WD 40 that will wash everything out and overtime it may not be good.
