Thanks G, after we looked at the gears we figured they would work but we had a heck of a time figuring how to support the truck, until we remembered our jig from our cam repair last year, it seems to be a universal jig/jack for everything!!!
Everyone knows the Triangle is the strongest geometric shape known to man. Look at how the pyramids have stood the test of time. And yes, never doubt a clown....
A good trick for seperating the 225 lb third member (chunk) is to take a couple of nickels (yep, five cents) and place them in between the top of the stud and the bottom of the casting under the pinion side of the chunk where it overhangs the studs that hold it into the axle housing. As you unbolt the nut, once it gets even with the top of the threads it will jam up against the several nickels above it and it will cause the chunk to seperated from the housing enough to get a couple of big screw drivers in and keep seperating from there. One person can pull chunk, but two are better...or if you have a forklift available, you can put the axle upside down on the chunk and lift the housing off of it. After it's drained, of course-
From there it's cutting the lock wire and attacking it with an air gun. It is possible to get it apart and leave the large diameter side adjustment nuts (round with holes) in place in the housing. I've always backed each side off an even number of turns, like 2...then pulled the differential or even taken on side off then pull the diff. Helps make sure that after you put the locker in and are going back together with it (why else have one apart that far- ) that everything is going in as closely to original as it can.
