got the 12 bolt torn down this weekend .
needed 2 new carrier bearings/races ( set36 timkin ) the originals had some water damage from sitting for years in 1 place. the races had some spots were the finish was poping up . pinion bearings and races looked great .
got the seals for the pinion / axles and yoke off the old 10 bolt and found a chewed up seal surface. every place in town over $35.00 my cost and order in for the repair sleave for the yoke . rock auto to the rescue $15.50 shipped to the door
also found the cross pin bolt was broken on the 12 bolt open diff.

common every day on this style . ( if you need to remove and save try this place
http://www.fabbriassociates.com/index.html ) mine was broken past the threads but with magnet and wiggle jiggle still wouldn't come out . so I got heavy

metal on it with a punch & 4lb hammer and drove the cross pin out sheering the broken pin off since I was installing a posi unit in the open diffs place anyway .
also beefed up the carrier bearing caps with ARP main studs . had to grind down the tops a tiny bit for the washers to sit flat. but anyone who has installed a ARB unit will have to have done the same on some model axles for the retainer plate on some models .
test fit of the new BIG THICK BEEFY diff cover
then I was going to swap over to the 11 5/8" x 2 3/4" brakes off 1 of my other 10 bolt junk rears till I found out all 3 sets of brakes from 12 bolt and 2 10 bolts were the small 11" x 2"

so I posted up a wanted ad in the sale section for brake parts .
