I have issues with my Baker hand wings too. I must be screwing up on how they are assembled because the main bolt that threads into the bottom of the mirror keeps loosening up when I make adjustments. That is supposed to stay locked tight and only the bottom part is supposed to turn with the wing itself.
I have everything put together the way it the diagram shows. I have extra white plastic washers and I have tried using them and not using them. Still not right.
