992 YJ Ujoint?

[NASH-TY-AMC]

I was going to change my rear DS ujoints, btw my yj has an 8.8 with slip yoke still. I pulled the shaft and the 2 caps connected to the slip yoke spin freely and basicly took no effert to get them out, but where it connects to driveshaft the caps fit like normal as does the diff end of DS. Is their something wrong with the yoke or did it have wrong joint to begin with?

i figured it out the ears where ujoint caps go one side is wallowed out and there is stress crack where the yoke meets the slip,weird.
