911 rear hubs with 944 stub axles ?, is anyone using this combination ? Options

Hi folks,

I heard rumors, that you can use stub axles from a later modell 944 (944 s2 or 944 turbo) in combination with early 911 rear hubs.
The trick is , that the splines of the 944 stub axle fits into the early 911 hubs. On the other side it should be possible
to use the outer cv-joints of the same 944 modell which provides splines for the 914/4 axles.

That would be a very cheap alternative to the expensive 914/6 stub axles ...

does anyone is using this combination ?

here's a small sketch of the proposed setup :

greetings ...

Clay Perrine from Rennlist wrote this a while ago:

"The rear hub used on a 914/6 is the same as the one used on the 69-73 911. The stub axle is a custom part. The CV axle is the same length as a /4, but it uses a different splined axle shaft and CV joint.

Here's a way to get a 5 lug conversion on the rear without ANY machining or finding the pircey 914/6 rear hubs. Get 69-73 911 rear hubs. Get the axles complete with the stub axles from a 944 turbo with the ALUMINUM trailing arms. The splines on the 944 turbo stub axles fit the 69 911 flanges, and they are the correct length. Remove the CV joints from the 944 axle and discard the axle. Put the 944 CV joint on to a 914/4 drive shaft. The 944 CV joint internal splines are the same as the 914/4 axle. Find a 915 transaxle from about a 75 911, and remove the drive flanges from it. If you got the correct ones, they will match the 944 CV joints and will bolt onto the 914 transaxle.

The extra bonus to this is you get beefier CV joints. This may benefit the V8 guys."

"911 half shafts will work, provided you NEVER let the suspension come to full droop or full compression. If you do, the CV joints bottom out at max extension and that WILL damage them. To make it work correctly you have to add a 1" spacer on one end of the axle.Wes Hildreth and I discussed this at length, and we measured a 911 axle and a 914 axle. He is the one that found the combo of 944 and 911 parts that I sent out, for that very reason."

I think you wind up with 100mm c/v's just like an SC+.

Does anyone know if the later hub centric hub fit into the 914 rear bearing?
