Some of you may recall that I've had diff noise problems that are not yet resolved. Well, I am at the point where I am ready to remove the diff and install one that I bought from salvage but upon examination, I found that the passenger side halfshaft is NOT fully engaged. I can move it in and out with a small screwdriver. It doesn't click into place, so the question is, could this be the source of my noise? I haven't examined things to find the reason yet (broken snap ring?) or something in diff is worn, etc. I would sure hate to change the diff if not necessary but also would be unhappy if I replaced the snap ring, put it back together and still have the noise. Here a few pics, any opinions?
