I'm in the process of replacing my left differential seal. I finally got the old seal out, but before I put the new one in I was curious about something I'm seeing on the splined output shaft. It seems like there is a snap ring or some other small piece of metal hanging down below the splines, situated in a groove on the shaft. I was wondering if this was normal or if possibly I messed up or moved something while trying to get the old seal out.
Yes, it's suppose to be left in place.
If you look into the hollow spline end of the shaft, you will see the slot in it to receive the cir-clip, when slid over the differential shaft.
It holds the diff end of the 1/2 shaft in place. Without it, the diff end can slide in and out on the stub. I'm not really sure it would cause problems but it could work fine or it could make the car vibrate or worst case it causes a break because it's not seated.
Interesting. I guess I'm just not seeing how the absence of that little piece could cause the whole half shaft assembly to come out or break or whatever.. :/

Gm uses a similar circlip on the outer cv joint of the axle end that goes into the hub.
That clip holds the swiveled joint to the shaft
If you ever need to chage the outer rubber boot you will become familiar, real quick..
Maybe you don't understand that the half shaft is not a fixed length shaft that is held in place by the suspension. The inner CV joint is built to allow the half-shaft length to change as the suspension moves. I personally don't want the shaft assembly sliding in and out of the diff as the suspension moves. It's possible it could break or cause a leak if it's driven while partially pulled out of the diff.

So there's ANOTHER one on the opposite side? I never saw it..

No understand how the shaft works.. I just couldn't see how it would pull out enough to cause any damage..especially with the spindle nut tight and keeping most of it from moving much at all. I know there's "some" play, but don't think it would be enough to cause any damage in/near the diff side. I'll keep an eye and ear on it though just in case...I just remember talking to a reputable forum vendor who works on these all the time and said he didn't think it would matter.
I could be wrong, but I think this "cir-clip" is keeping me from getting the half-shaft back in the differential. I can't get it to slide onto the spline shaft more than a bit, and I think its because this clip is hanging down in the way.
If I manage to 'tighten' the circle of the clip, is that going to keep it from doing its job once the shaft is back in?
Or is there another reason I can't get the shaft to go back on?
Make sure to clean the shaft splines in both the shaft coming out of the diff & the hollow end of the half shaft sliding over it
Make sure there is no rust on either part.
Spray some type of light lubricant onto both mating areas, including the clip.
You shouldn't have to close the clip for the shaft to slide over it.
Have the half shaft free at the other end, and not being hooked up to anything at this point, & see if it will slide in..

I had that exact same problem when doing mine. I wound up talking to a corvette shop/vendor owner who agreed that it probably wouldn't hurt to take it off and leave it off. I was doing it by myself so couldn't have anyone there to help push it up as I pushed the shaft in.
Did you actually try moving the inner CV joint hub to see how much play there is or did you just assume there won't be any play???
I understand your point. However, do you really think it could come out far enough to cause any binding or damage?? Like I said, I'll keep an eye/ear on it and play around with it tomorrow to make sure there isn't much slack..
I am looking for snap rings for the differential pinion shaft on my 81. I am not finding them anywhere. I purchased a new shaft and the snap rings are shot. Any ideas where I can get them?
