Ok so I couldn't figure out why my rear diff kept popping. I thought maybe the auto locker. Well I got underneath it just now. And where the yolk connects to the rear diff the plate on the diff is loose. What do I do?!

If I understand you correctly: there's a big nut holding the flange (?) to the diff (or something to tighten up), need to drop the shaft first to access. Maybe change u-joints since you're there and they've been taking a beating with those pops.

Are you talking about the dust cover? just silicon it, weld it , jb weld it, or just tear it out of there.

ok that makes sense. Ive never messed with the axles before. ill try that first. then if nothing else ill try mrfuelish idea.

if it's the flange your talking about that's a whole different story,do you have some red loc-tite ,an air impact, and a punch, a floor jack, and a couple of jack stands?

what exactly do you mean by loose, and what component is moving in which direction?
