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.:D

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.:D

looks good on there, thanks.

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

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.

[boygenius]

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.:D

I think it was WHY TYPE 181 FLANGES.

I don't know how to make a link out of it, sorry.

[Alex]

Doh,

I should have used the search function.

Got the info I needed.

Thanks a lot guys,

Alex

[zen]

let us know how it goes alex. yeti sent me some axles off of a vanagon i plan on using.

i got my arms prepped for removal today. just have axles, trailing arm mount and spring plate and they are out.

[Alex]

Well I guess I will call some Porsche wreckers tomorrow or after new years to find some axles. I need 540-550mm axles from a 86 Turbo (I read so in the other thread). Those vanagon ones should work too.

Alex

[boygenius]

Try ebay for your axles. I got both of mine for $140 including shipping, from my experiences wrecker yards usually want double what the part sells for on ebay.:(

i found rear susp off a 87 944, axels arms rotors calipers ect. what is this worth? thanks!!!!

[Supa Ninja]

I got mine ('86) for $100 from some dude in LA.

[kiwivw]

Try partsheaven as well, i used them for some of the porsche shifter parts i needed.
Good service.

I paid about $300 for my complete rear suspension but that included torsion bars, spring plates, aluminum torsion tube end caps, trailing arms with new discs and axles.:D

Hi Alex, I just did the conversion with MBT's monoball setup. I used the 86Turbo cv and axle shaft with the 181 flange at the gear box. The setup with the torque bar setup is good. Its like running on rails!:)

[SilverBullet]

Oh yes I got the whole axle setup from PartsHeaven. Good service!:)

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. :)

[zen]

looks like these are 19" axles. :bawling:

can still use his arms, but now i have to look at hubs and disks again and make sure i have something that can work with my 951 calipers on late arms.

[SilverBullet]

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

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

[zen]

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 :rolleyes: ). 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)?

[SilverBullet]

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.
