My LR2, which automatically repositions the side view mirrors when reverse is engaged, has gotten very jerky in its movement.

I imagine it needs a simple cleaning/lubrication. Ant tips or tricks on how to access the internals?

 

see attached on how to remove mirror from the RAVE (factory name for the shop manual set, download entire if you like below).

 

I'm sorry, I don't know about this topic. I'm learning a lot here as well.
