CV Joints

[910Esprit]

Esprit CV Joints appear to be 108mm diameter, 40mm deep, 28 Spline, 10mm bolts with 94mm PCD.  (Originally manufactured in Germany by Lobro).   These dimensions are the same as the Porsche '930' CV joint used on many 911 variants of a similar age.

If the Porsche item is not suitable, I can only assume it does not articulate through enough degrees (doubtful) or perhaps the internal Spider somehow has a different offset, or there is something else I have missed?   

What's puzzling me is that if it was that straightforward, the Specialists would be selling them....   Had anyone else used the Porsche spec items as a replacement?

Aren't they standard GKN dimensions?  These are readily available.  Also available in lightweight versions.  Search for MS3N044.

It certainly looks that way.  It just seems odd that PNM & SJ dont appear to list replacement CV joints, which made me wonder if there was something odd around the Esprit versions

Yes I saw that and it was the price that sent me in a different direction!

They likely rarely need replacement I would think, the joint is running pretty much straight most of the time apart from a small suspension movement unlike a front wheel drive application where they are often running at tight angles.
