Custom half shafts for VE diff in Perth

[PeterAllen]

On the VZ diff I'm using the CVs are a universal type known as Porsche 930 CV. They are very popular in off-road buggies.

On the Holden they usually have one fixed CV (27 splines), which does not allow lateral movement, and one 'plunge' CV (28 splines) which allows for the differing length require of the axle as it swings through an arc. I can't remember which goes on the inner and which goes on the outer end of the axle. The high performance Holdens have plunge CVs on both ends.

You can buy 28 spline chrome moly axles from the US for around $200 (around double that for 300m) in a range of lengths (be careful as they also do 33 spline axles). In my case I have to buy the shortest ones 15 5/8" and chop 25mm off each end. They come with up to 3" of spline and with the extreme axle swing on off-roaders the CV not only has 'plunge' but they also slide on the splines. For our application you will need to cut two circlip grooves into the spline to lock the CVs into position along the spline.

Here is an example of a supplier:

axles | 930 axles | race axles | racing axle | 934 axles | 300m axles | gun drilled axles | IRS axles | VW axles | racing axles | drive shaft |

Having stated all that I think the VE axles/CVs are the same. The prices I was quoted to have them made here in Oz was $1000.
