    When I get back from vacation I'm going to look at a FF14 bolt out of a mid 80s van. I know I'll have to relocate the perches and shock mounts but I have a question about IDing a gov-loc. I know they have 3 cross pins but does an open dif have 3 also? Does it look simular to a 12 bolt gov-loc, big chunk, lil springs and stuff? Never been into a FF before, will the same hub socket you use on the front work on this axle? Do you need a hub socket to get into the brakes? I'm so ignorant. /forums/images/icons/confused.gif If this thing turns out to be a gov-loc is Chevy the only place I can get an open carrier to run a detroit? Any body know the cost on that?

    You don't need a hub socket to work on a rear axle, but if you swap in a 3/4 front axle, you will need to buy a 3/4 socket.

    Gov-loc has 3 posts open has 4.

    If it is a gov-loc get a gear set + carrier from the jukyard (after inspecting it). What ratio do you want?

    To pull the hubs you will need the hub socket - mine was the 6 point socket (not hex).

    I can get the KD tool number for you if someone doesn't post it ...... Anyone have it memorized?

    You can buy a new open carrier from 4 wheel parts for about 160.00 or so. Make sure of the gear ratio you are going to run as to get the correct carrier, 4.10 down or 4.56 up.

    For some years you do need a hub socket. My 14-bolt came out of a '74 GMC pickup and has 6 slots on the hub nuts, instead of the 4 slots used on the front. I've got a neat socket from Mac Tools that fits both the front and rear. /forums/images/icons/cool.gif
