Hi Tomas,

you need your supposed "chock". There is a ring preventing the joint from slipping out of the gearbox. With a crowbar or a very big screwdriver you can apply the necessary force to remove the joint.

Cheers
Andreas

P.S. I have some spare axles if you break yours.

Hi again,

I have not been able to remove the CV-joint. This weekend I borrowed a really strong extractor. It got a good hold of the CV-joint, but was not the correct design to pull it off.
However, I used two(!!) hydraulic jacks, capable of 2 tonnes each, pushing on the extractor, which in a normal world would make the CV-joint come out with a "pop".

In my world, it just sat there. I pushed as hard as I dared, probably around 2-3000 kg of push, but it would not come out!

I officially have now given up trying to remove it, and will purchase "gasket on a tube" to try to seal the gearbox so I can finally drive my little Kewet 1993, version 3. At least I tried...!
