i was googling and such and i found this link

now my question is your pic it seems it would slide over gear and the right wheel would get power... but if that didn't work the Left side should always spin no matter what as it differential housing number 35 right... so if that fork doesn't enage. the right side should always spin if the front drive shaft is in gear and turning right?? and since it isn't turning
would that mean that differential housing is broken?
