Ive taken the Gearbox out of my Subaru Brumby. and have removed all bolts necessary to separate the three sections of the box, however I am unable to actually get it apart. I have a small amount of movement in the back two sections but they will not separate. I need to overhaul the front diff. Any trick to getting them free . I cant find any info on actually dismantling the box itself on Youtube /or Gregory manual. Just need to get the two rear sections off. Any info would be greatly appreciated.
