Which axles to use with al 944 arms?

[Alex]

I need to know which axles I need to use with my early 944 Turbo aluminum trailing arms. I am concerned about the length of the axle.

Do I need to get 944 Turbo ones or can I just take 944 ones?
Is there a length difference?

Thanks a lot,

Alex

I don't know if the early aluminum trailing arms and the late aluminum trailing arms have the same axle lenght but I think they do. I am using a set of 1987 944-S axles with my stock type 1 tranny and 1987 944-S late aluminum trailing arms. The axles are 21-1/4'' long. They do not bind or bottom out at any point of the suspension travel. They use the VW spline so type 1 and type 2 cv's will slide right on. They are a little thicker in the middle but you can still get the type 1 cv boot over the axle. Hope this helps.

boygenius,
what is that rear wheel, and what offset?

Alex,
The early 944's used 16" axles, same as type 1.

Porsche 18" turbo twist. 18" X 10" -ET65. Part number 993.362.140.04

No wheel spacers needed. Plenty of clearance with the tires on with late aluminum trailing arms. Hope this helps.

looks good on there, thanks.

So I need Turbo or S axles that were on a car with the al arms?

Hi Alex,
I used the 944t axles on the 86 944turbo trailing arm fits just right. Cheers.

well i can confirm that '87 944S axles are 25 splines and not interchangeable with VW CVs.

silverbullet, i just came back to this post and saw you had info i am requesting in a different one (i am way to scrambled at the moment ). looks like you have the info i am looking for with the T181 outputs, porsche axles and ali arms. follow-up though:

are the axles 21" (measure CV mounting surface on the output flange to the stub axle)?

Hi Zen,

I just came back with the measurements under the car, I can't exactly measure the axles accurately but with the measuring tape, yes its about 21'' from output flange to stub axle. Hope it helps The car has been on the road for about a month plus and everythings seems alright. I'm happy

[zen]

exactly what i was looking for. there was just concern over the added length of the T181 CV. sounds like it is a non-issue.

alex, i can't seem to find it, but several months ago we had a very detailed thread on options in this area including output flange and CV options. i still have yet to fit mine up. that will be happening in the next two months though.

I use www.pelicanparts.com as a cross referance manual.

They are showing that these axle assemblies are the same.
Manual transmission only.
1. 1985 1/2 - 1987 (944 and 944S)
2. 1987-1988 (924s)
3. 1986 (944 turbo)

1987 and later turbo axles use a differant spline pattern than VW so you would have to use only porsche cv's. Hope this helps. If you need any more specific measurements let me know.

genius, what about axles from an '88 944NA? seems outside of what you have above. i am mostly interested in the ight length. i will switch to Porsche CVs if i need to. i have to check if these are the wide arms too.

[boygenius]

I don't really know if they would be the same. The differance in years might be as simple as a different spline length or something like that. If you find a set for sale just ask the seller to count the spines and measure the length. if they are the same as the earlier ones they should work.
