Somehow, I was picturing the inner green cup as being ON the CV axle. I thought it must be the inner "bulge" on the CV unit. IOW, I kinda thought you were talking about the non-accordian inner rubber sleeve/protector that's held on by bands.

Cup sounded more like rubber than metal.

Now that I understand that, I assume the CV axle simply slides in the cup -- which sits at the outer end of the axle housing. How often do people worry about pulling the outer axle bearing for replacement or service?
Not to split hairs ... but ... it's what I do.

The green cup is part of the Constant Velocity (CV) Joint. A CV joint is in reality a bearing on steroids & the green cup is the outer race.

Part of the problem with talking about CVs & half shafts is that there is so much mis-use of terminology and slang terms that it all gets very confusing.

There was a thread a couple of years ago called "CVs for dummies" that had a drawing & the correct terminology. Also, last time I checked, wikipedia had a pretty cool animated graphic of a CV joint.

I've been told that the term "half shaft" really means the entire assembly (from splined shaft entering 3rd member to splined shaft entering hub). More commonly, the half shaft seems to mean what the pros call the "center shaft" which is the solid shaft between the two green cups and includes the "star" (inner race), Ball Bearings, & Cage.
