I have a 10 bolt 8/5 inch rear end. I don't know if it's a semi-floating axle or a full floating axle. Does anyone know what type of rearend I had, or how I can determine it. The bearing and seal replacement procedures for the semi-floating is easy, while the full-floating is a long pain in the *ss procedure that I think I'd leave to a pro. Something tellms me I probably have the full-floating, since that's my type of luck, but could anyone help me figure this out? Thanks

after an hour of searching various search terms, I think I may have found my answer on this page: http://www.offroaders.com/info/tech-corner/facts/axles/axle.htm#GENERAL MOTORS (Chevrolet/GMC) .

1983-87

According to this page, I have a semi-floating, which means tons of happiness. However, can someone still confirm this?

Well, to update everyone, I have a semi-floating axle, and I replaced the seals on the rear axle with little problems.. I'll edit this later for a more thorough write-up of what I've done, but I'm tried right now...
