I have spent alot of time on the f4ael / f4eat,,, they are not the easiest ones lol ,,, I have found went putting in the last drum .. (forward) you really have to turn the axel spline while pressing on the drum then clunkit moves in ... sounds like you are locking up one friction yes ??? also oneway clutch can be installed in both directions make sure the smooth side (without the tabs) faces towards you or else it will bind !!!
