Driveshaft

I'm replacing my u-joints and when I removed them this ring of either compressed oil or plastic broke off. Does anyone know the significance of this? Should it be there or is it trash?

Should be considered trash and there should be a solid ring that goes in its place.

Factory injected plastic to retain the caps, replacements will have metal clips.

As a guy that has never had a new vehicle I've rarely seen that, and the ONLY time I have seen the oem U-joints with that plastic has been on CUCV's and they have been some of the oldest vehicles I've had, kinda odd.

Likely lowest miles per year though if you got them fresh from Uncle Sam
