Rear 5-Lug with 944 Parts, PART II, update & pics ... Options

[SirAndy]

so it looks like there's going to be some minor machining required after all.

turns out, the 944 Turbo CVs are 4mm thicker than the 914 CVs which means the 914 axle shaft has to be machined down a bit for them to fit.

see pictures below ...

3 - 4 mm needs to be removed from the 914 shaft to accomodate the 944 CV

Dimensions:

914 Shaft, dia. = 25mm, length = 514mm
944 Shaft, dia. = 26mm, length = 540mm

914 CV, dia. = 94mm, width = 31mm
944 CV, dia. = 100mm, width = 35mm

what if i have 911 hubs that fit the 914 wheel bearing and i use 911 stubaxles and halfshafts and change the drive flanges on the transmission to 75-76 911,
whouldn't that work just fine ???

Only if the c/v's are 100mm and the 911 axles are supposed to be too short anyway. The earlier 108's require the earlier stubs and output flanges. With Cays config the 944 c/v's have the 914 (VW) spline and you could use the 914 axle shafts.

You don't have to change the axle shaft if you use the 944 axles. The 944 and 914 axle shafts are the exact same length.

If you are a cheap bastard, you can buy a 944 stub axle and one CV joint, and put it on the 914 /4 axle. Then use the 914 inner CV and drive flange.

If you want to do it right, use the 944 axle complete, and the 75-76 911 transmission drive flanges.

Oh, and using a 911 axle is asking for a failure. They will bolt up, but if you EVER hit full droop or full compression you WILL bind the CV joint and damage it.

Then you will be out the cost of the 911 axle parts, and your 914 will be back home on the jackstands.

Here, Clay says the 914 & 944 axle are the same length. But Andys pic, shows the 944 axle is longer, is it the right year?



For a 4 cylinder teener, this would be a cheap way to do a 5 lug conversion, once everything is worked out?

For a V8 teener, I wouldn't do the axel and CV upgrade, unless you have a 915 or better tranny.

WHY?

It's cheaper to replace CV's than it is to replace 901's, especially if you've spent money on a intermediate plate and or H gear.
If, you beef up the CV's and axels, to handle more HP
than the week link becomes the tranny.

This is my 500,000 cents, the price of a nice tranny. (IMG:http://www.914world.com/bbs2/html/emoticons/happy11.gif)
