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 :

"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."

What exactly does this mean? I just finished my rear setup using 911 axels out to the hubs.

Does this mean that my CV's will bottom out on the trailing arm? I really cant understand a situation that would make this possible (but what do i know)

He means that when the axles are at max extension the C/V's are still being pulled apart beyond max extension. I have also read that this is not true as the 911 joints are thicker. Did you compare max compression and max extension lengths between the 914's and 911's before you mounted them? If not, jack the car up and see if the axle shafts have any play(back and forth slop) at full droop. Whatever you find there will probably be the same as when the shock at full compression.
