Thanks for the info, gives me something to investigate. I will pull the boots off and have a look. Always handy to hear from someone with expertise in such things.
Cheers,

Subject: [Syncro_T3_Australia] 930 CV upgrade
Date: Mon, Feb 11, 2013 9:35 AM
I am running genuine Lobro Porsche 930 CVs on my offroad T2. The vehicle is only lifted 25mm above stock height but has an extra 50mm of down travel. I went with the 930s because I was worried about them popping out on full suspension droop.
My thoughts now are that I really didn't need them.
Unless you run an offroad style boot that goes over the whole CV outer, you don't gain much travel because the standard boot flange has a small hole which fouls on the shaft at large angles. I run aftermarket boots that go over the CV Outer. If you did this with a standard VW joint I think you would get good travel.
This may be happening with your VW ones. You need to jack the vehicle up so the wheels are dangling with the boots off to see whether the shafts are clearing the outers and that the balls are tracking within the edge of the joint.
Also timing the joints could net a little extra travel.
Having smaller CVs could be an advantage in that you want them to fail before internal gearbox parts and the 930s are much stronger. I have never known a VW CV to fail anyway,
Neil.

Hi,
Finally got my off-roader up in the air where I wanted it,
but now on the limits of the CV’s. Took it for a drive and the CV’s were
noisier than I would like, could be the balls just running in a new position
but would not like to push it off-road and get stuck. So looking at 930 CV’s and shafts and 16”
front outers for more articulation. Is anyone running them and how do they find
them?
Cheers,
Michael Roberts
