I have an 87 2wd Westy with a manual transmission and am in the process of replacing my CV joints with new german ones. I did my pax-side axle no problem. When I went to do my driver's side axle, I discovered I somehow have a completely different axle with 24 splines (if I counted correctly), and the new CV of course won't fit. The new CV is also a few mm less in depth but the same diameter.

What kind of axle am I looking at here? Is this a 930 axle that a previous owner swapped in but only on one side? And if so, I'm guessing it'll have different stub axles too?

'87 - up Porsche 944 turbos had 25 spline axles with 100mm CVs. The axle length is close to that of the Vanagon, so I'm pretty sure that's what you have there in your hands.

Thanks for the response, and yep, it was apparently a 944 axle, or perhaps some aftermarket axle with 944 CVs. Anyhow, I was able to hook up with one of the local vanagon gurus and get a standard VW axle and all is well with my new CV joints.

Thanks again guys!

Internet lore is the 944 CV is better for lifted vans. It makes no sense since the 944 has a lot less cv angle than the vanagon. I believe the balls are smaller ID which may be why. I’d take those 944 cvs apart, clean and inspect. They would have some value if original and in good shape, not pitted.

the porsche axle he had l believe was a cheap nasty chinese part.
it's on the floor in my garage currently
l gave mr run8stud a genuine vw axle.
he's back up and running
l expect next time l do a dump run, that's where it'll end up.

Another consideration is it could be an aftermarket axle, and nothing else will fit on it.

I had the case with an Audi 5000 Turbo chinese axle to fit the Syncro 16" style outer cv joint.

It had 28 splines, but wouldn't match anything Lobro, weird sizing only matched their own crap... Evil or Very Mad
