The actuator part has very little to do with it. The only load on the actuator is from moving the clutch to engage but that doesn't change whether it is locked or unlocked.
I will be taking mine apart to upgrade to the larger spline gears and axles. I have the parts now but I am thinking of referring to 5:13 when I do it. I will need to pick up gears. Is there any parts I should pay attention to while I’m in there?
