Axle Shaft Snap ring and O ring

Hey everyone... In the process of replacing my differential mount bushings I found that my passenger side axle shaft had some play in it at the junction of the CV shaft and Axle tube.

Pulled off the axle tube without paying too much attention and found that there was a snap ring and o ring that were still on the axle shaft.

Replaced the axle Bushing / bearing and the tube seal and everything is nice and tight so I'm good to go there.

Every diagram I can find shows the O ring being outsided the Snap ring and I just want to verify this if right before I get my new diff bushings installed and throw the diff back in.

The more I look at this there is no way the O ring can be outside the Snap ring... If I tried to insert it this way it would just push the O ring back behind the snap ring and might even trash the O ring...

Thanks,
--Tom--

Yea, looking at your pictures and reading your description, I have to agree that doesn't look right, the O-ring looks like it would get pushed past the locking ring as you push the CV shaft over the splines.
I'm assuming the O-ring is there to keep grease between the splines from oozing out and slinging as it spins.


Look inside the CV Joint case, that should fit over those splines, is there a groove for the O-ring to fit inside? Remember there should be a groove for the snap/lock ring to expand into and lock the CV joint onto the shaft, if there is an additional groove, perhaps the O-ring is suppose to be inserted in that groove before joining the two pieces together.
On the shaft in the photo, there seems to be a groove at the end of the splines, that might be simply left over from machining, but it does seem like a place for the o-ring to end up and seat.

Ok, after checking everything out the only place for the O-ring to go is behind the snap ring in the pics I took... Not sure why the diagrams show it differently but mine is back together and doing fine!

A lot of diagrams that are easily available tend to be more for parts identification purposes than technical schematics of fitment any assembly.

You can get good diagrams through subscription services for service facilities, but not a lot of non-techs have access.

I totally agree that o-ring should either go down behind the snap ring, or inside a groove on the female end.

I cleaned out the female end and there was no groove made for the o-ring... I even tried to put the ring in there and it wouldn't fit.

I have the Alldatadiy subscription and it didn't have anything about the parts at all... Not even sure why I'm paying for it!
