944/951 stub axles? Aaron Cox? Andy?, Which 944/951 are needed for 6 bolt CVs? Options

can you just use a 944 dust seal rather than make a spacer, even if the seal wont be sealing anything?

by 33 spline pre 86.5 cv, do you mean turbo, or it does not matter ?

Why not use the 100mm 911 stub axle? It doesn't need the spacer. Also, you can use the later 911 hubcentric hub if you make up a 5mm spacer (Difference in bearing width) or machine it to the old length.

Ok.. I have been driving around on this setup for a year now......

From the outside to the inside......

1. pre 74 911 hub.

2. 914 wheel bearing.

Here's where things get varied...

3a. 944 stub axle (find one with aluminum trailing arms.. it has the right one)

with spacer the same thickness as the step in the stub axle. This is to hold the inener race of the bearing in place.

3b. Alternate method. Take the 911 hub and cut the same thickness off the back of the hub as the step in the 944 stub axle.

4. 944 6 bolt cv joint on the outboard end.

5a. 914 /4 axle shaft. You have to cut it behind the splines to accomodate the 944 CV.

5b. If you did 3b, then you can use the 944 axle shafts. The difference in length of moving the stub outboard will allow you to use them.

6. 944 6 bolt cv joint on the inboard end.

7. Paper cv joint gasket from a 76 911.

8. 76 911 drive flange from a coarse splined 915 transaxle. It will bolt into a 901, and has the same bolt pattern as the 944 cv joint.



That is the parts and modification list.

Any questions???

It's not the 944 dust seal. The spacer holds the inboard race in the wheel bearing. Without it you will have some very excessive play in the rear bearings. You will know this because you can't get the brake pedal to pump up due to pad knockback, and the wheels will wobble around.

Why not use the 100mm 911 stub axle? It doesn't need the spacer. Also, you can use the later 911 hubcentric hub if you make up a 5mm spacer (Difference in bearing width) or machine it to the old length.

The 911 hub uses the wrong sized cv joint. It won't match the 944 cv, and the internal splines of the 911 cv are different from the 944/914-4 cv. Also, the 911 axle is shorter and wont' work on a 914 without a bolt-on spacer. And that adds another point of failure.


Wes Hildreth and I came up with this setup over a year ago.. and I am the first person to actually run it.

The 911 stub axle comes in 108mm 4bolts 2 roll pins (this is the one you don't use) and 100mm 6bolts - this is the one you can use. I didn't say anything about using the 911 c/v's or axles.
