Yes. There are further steps to remove the actual diff from the housing once you have it on the bench.

pull driveline. unbolt the housing. pull off. sometimes the diff stays in the trans and you pull it out. sometimes it comes out with the housing, and you pull it out. slides in and out. be careful of the shims inside on the output end.

also, the flange removal is what i think requires special tools, not the diff proper.

wow thats a lot of weld :) mine has just an inch or a little more on three sides on the worm gears only, and holds my 800+ AWHP and drag launches, etc just fine.

i run Motul Gear Competition http://www.motul.com/us/en-US/products/108 in mine, but thats because it is recommended by the manufacturer of my dog box.
