question axle fitment

[Stuart]

I've got the axles of a 944T 1986 porsche to mount in my 1303 beetle with early alloy arms. I've dismanteled one side(inner side) of the 944 axle as i want to bold a 90 mm bug CV to it. The bug CV fits with a little hammering but know i have a question. As the bug CV is a little smaller as the 944 CV, so when i drive the bug cv over the 944 axle the splines on this axle are just a bit wider. Is this a problem? It seems that the bug cv sits really thight on the axle or should i shim the CV out on the axle side? I hope my question is understood by you all because my english is not all to good. Greets.

Stuart, Are you arms like these:


These arms need the axleshafts of the same car.
What length axle shafts have you got? Are you using the 1303 axles or the longer ones from the same car as the ali arms?


Is your intention to use in this order:

Porsche hub
Porsche arm
Porsche hub flange/stub-axle
Porsche CV joint
Porsche axleshaft
T1 CV joint
T1 output flange

If the splines are not exactly the same profile, they don't fit and may break under abuse.

If your Porsche axleshafts are the same length as the 1303 axleshaft you can do:

Porsche hub
Porsche arm
Porsche hub flange/stub-axle
T2 CV joint (needs clearancing for T1 circlip)
T1 axleshaft
T1 CV joint
T1 output flange

T181 output flanges are the holy grail of this conversion and it would be a doddle, Porsche strength everything!

Do you have a digi camera? That would be a great help to get help.

I've got the axles that belong to the organ spender. They are the long axles from the 944T (+-53 cm). My intentions were to bolt the setup you mentioned in your reply(the first setup). The VW CV and porsche CV differ about 4 mm from each other in tickness. I've got the early arms(I believe the same as on your photo)

Yesterday evening searching the web I discoverd a few VW 181 gearbox flanges. Probably I will buy these baby's what will make the setup very easy(I think). The flanges are I believe 50 euro + a piece + shipping, not very cheap but he, buying the othet parts to make it all work will probebly cost the same.

As to the shock absorbers. I've bought a pair ao yellow konis for the back. I will drill the bottom hole for the larger bolt. I can live with this because I won't race with my convertible. And yes, the shocks are not complete paralel as with the original steel arms. I's only 1 or 2 degrees of so it can't be a big problem. For the rear I will bolt the 18 mm porsche sway bar as the convertible is at the rear a lot heavyer then the "normal" bug. Keep yp the good werk Matt, it's verry apriciated. Greetings

PS: I've got a digi so let me know and i will photograp it for your judgement.

Any picture of any VW project is worth a good look!

5 good pics of your verts progress good sir! Please Post 'em up or email them to myself.

I'm very interested in the T181 'flanges I found some in the states at $35 each plus shipping and duties. A very similar price I suppose.

I don't forsee a problem with drilling the bottom bush, I did this and I now have 14mm shouldered bolts in my steel arms. On your ali arms use the 951 washer.

Have you considered the possibility of redrilling the top shocker mount hole out to M14? This could in theory compensate for the mis-alignment but would be tricky to drill.

Note, the steel in the bushes on the 951 shockers have a wall thickness of ~4mm.

I've bought the yellow koni's for the bug and not the ones intended for a 944 because I understood that the 944 ones are to big for the bug.

if you guys could identify sources for T181 flanges and such, that would be greatly appreciated. i am getting ready to step through the same thing.
