So it the afternoon before I got to work on the 914 again. First I started to look at the gearbox side UJ. It took me 15 mins to get the clip off! Then another 10 mins to work off the UJ. Strange because it's meant to be looser so can be removed by hand. Looks like it needs replacing because of wear but I'm struggling to find a source of UJ with 33 teeth.

Here is a very good video and how to rebuild the UJs

Then I when to removing the hub. I used a combination of M12 bolts and nuts to slowly move the hub. Then the hub hammer did the rest.

I was so excited when the bearing from the freezer went in with only finger pressure but it was shorted lived. The inner race separated when I was cleaning the frozen off it. Perhaps I didn't wait long enough but the hub was reluctant to go into the bearing. I tried to tap it in but should of used an installer like in the picture. I've decided to get another bearing. Doesn't anyone have a suggestion other than Design911? Unfortunately, the car is now on an axle stand. Exactly the situation I was looking to avoid.

Here is a very good guide. I should of read completely before guessing.

The rumour was that using 914 parts would be the answer. Andy (Lightweight_911) had kindly supplied me with some 914 Output shafts, and I picked up some 914 C.V's and Driveshafts on Germany Ebay. The 914 Driveshafts are 47,0cm long, the magic number I needed was 41.5cm , so after considering having the 914 shafts shortened ( don't really know how this would be done without he things snapping when in use ) I looked again at the original Driveshafts that came with the car.........41.5cm!!! and these have the same splines as the 914 C.V joint !!! Can it really be that straight forward

So long story short....I believe that this is finally the correct combination:



All the C.V's are currently in a friends Ultrasonic Cleaning Bath, so I can check the condition. HOWEVER, I do need another 901 driveshaft if anyone has one lying around....the other Shaft that was fitted looks like it came from something else.

I believe that this is the original, and what I need:
- 41.5cm Length
- 27.0MM Across Splines
- 33 Splines

Not sure if this is of any use.....But I remember having my own battle with 33 spline driveshafts.

I used these on the 912, surprisingly good:

Should be interesting - it’s 996 3.4 with a 40% odd power increase over the outgoing 2.7. I will have to learn how to drive around a few new problems, like traction!
