CV Joint Help.

[awdbandito]

So I am rebuilding the CV joints on a '75 911. It has the later style axles on it.

When I took them apart I didn't realize they aren't symetrical.

The outter race has a groove machined in the outside of it, and I figured out the race is offset towards the outsides of the axle.

The inner race looks symetrical, but the outter edges have a differrent edge on them. once is thicker.

The washer on the edge is domed, which way does the dome face?

Any info, or better yet, a diagram would be great.

Every other CV I have repacked can't be reassembled incorrectly.
Maybe this one can't either, but now that I've noticed these items I want to make sure it is correct.
Thanks,

Usually the groove on the outside part of the CV is outward. The inner part of the CV (when assembled) has a relieved part of the splines. This goes inboard of the axle. The conicle washer faces outboard from the center of the axle. The ball bearing grooves (when assembled correctly) are opposite of each other. Meaning, when you look at the assembled CV joint, You will see small groove mated with wide groove. If you assemble them small to small and large to large, the CV will not articulate. Sorry no pictures.

I have not run into problems ignoring which way the outer race faces, nor which way the inner race faces. Groove and bevels notwithstanding.

Of course, if you get the relationship of the outer and inner wrong in terms of rotation, you get the locked joint.

The conical washer is obvious. One way its outer edge has something to push against (the center race), the other it doesn't.

However, I am unsure if installing the conical washer wrong would matter. Or leaving it off entirely would matter. I had an aftermarket set of axles which were made with extra long splines and no lip where the splines ended toward the center of the axle. The idea here was to let the CV and axle slide freely on each other. This notion came from Baja 1000 and the like cars, with their huge amount of wheel travel. You might think letting th8ings move this much might cause trouble, but it did not. These axles worked just fine on my track car (although, being hollow and a tiny bit under strength, they broke, which was not just fine). Easier to install, too.
