Hi coolgasbi; I checked the blade grips & one is real smooth & the other scrapes & drags!Are they bad? If they aren't then done force them. Till your feathering shaft in the blade grip and see if they are notchy. If they aren't you are fine and don't fix what ain't broke
As far as if they are notchy they are bad already, you can use a small screw driver to get in there and tap them out. Of course that'll hurt the bearing a bit. But if they are bad then they need to come out anywaz.
Hope it helps
Fly safe!!have fun!
