Looking at the gear without the paste on it, you can tell they are used. It is a crap shoot with a used set especially not knowing the history on the rear end. You can run it and see if it makes noise. More than likely it will. But increasing the BL could also create a noisy rear. Having the carrier fall out due to no preload on the carriers is a little wondering. If it were me while this is apart. I'd spring for a new set of gears and bearings and not worry about it--OR run it and see what you've got. It may be fine. How's that for being non-comittal?
