One of the hardest tools to find when working on these is the tool you use down the axle tube to adjust the carrier bearing adjusters. I wound up making one. I found a bolt that the head was just a little to big. I wound up grinding the flat sides of the bolt til it would fit into the adjuster. I ground the flats at an angle so the bolt head wouldn't slide all the way thru the adjuster. I then welded a 1/2" drive 7/8" socket to the threaded part of the bolt. Now I can use a long 1/2" drive extension thru the housing ends to adjust the carrier backlash and set the carrier bearing pre load.
