Is it the sun gear that the driver side splines of the out put shaft go in to? I'm 21 trying to teach this stuff to myself, so sorry for my ignorence. Soon as the it quits raining I plan on starting on it again. You shouldn't be able to pull the output shaft through with out removing to c clip right? And when you shove it back in it should grab something correct? I'm looking at diagrams trying to figure it out.
