When I do maintenance on the rear end I've replaced the stopper ring but in reading in the manual (Clymer) there is a note "Do not install the stopper ring in the groove in the end of the drive shaft splines. It is used only during manufacturing and does not need to be replaced".
My interpretation is they mean the pinion gear end of the shaft. That doesn't seem right as omitting the ring the shaft it doesn't "snap" in place.
Am I on the wrong end of the shaft?
What end is supposed to do the bulk of the in and out travel?
It seems that the circlip and spring seat could be left out.
Sorry but I can't find any info on this, I'm just confused.
