it's been a while since i started this project. i had all the parts, but i was waiting for the right time to redo the complete rear suspension ...

yesterday, i went up to McMark's and we took out the old trailing arms and axles and shocks and prepared my new trailing arms and the axles.

McMark finished the job today, and now i have:

- new (unbend) trailing arms
- new mueller roller bearings
- new koni adjustable shocks
- new axles with brand new 944 CVs

Andy

PS: for the axles, i used, tranny to wheel:

915 (911, '75 - '79) coarse spline 6-bolt 100mm outputshafts ->
944 100mm CV ->
modified 914 axle shaft ->
944 100mm CV ->
911 ('75 - '79) 6-bolt 100mm stub axle ->
911 ('69 - '73?) hub
= real 5-lug!


on top, the stock 914 axle, bottom, the new axle using 944 and 911 parts:

and installed:

the main benefits of doing this, IMHO:

- 944 CVs are still readily available brand new for reasonable prices.
- 944 CVs are slightly bigger and wider than stock 914 CVs.
- real 5-lug hubs instead of redrilled 914 hubs.

Nice work, Andy!
What did the mods to the axle shaft consist of?
Pat

not andy,

but you have to turn off a "bump/lip" on each end of the shaft where the stock dust boot sat iirc

I think you will see the yellow through your wheels.
sweet.
Looks pretty fast on those jackstands!

Nope. The 944 CVs are wider, so they need more room on the axle splines.

ahh yeah. i lied. LOL.


that makes it mo betta

OMG. That's delicious.

That is exactly what I did to 914-6 axle shafts to make 911 CV joints fit on them

What model and year did the stub axle and outputshafts come from?

Where is the 100mm measured on the stub axle?

I have one large four bolt stub axle and one six bolt. Not sure or the origin.

The outputshafts I have are from an '86 915 and are also four bolt.

Thanks

Eddie

915 output flanges and 911 stub axle came from a mid to late '70s 911 (~'75 - '79) and the hubs came from a early 911 (~'69 - '73?) ...

100mm is the dia. of the CV, so the flages and stubbies fit a 100mm CV ...
Andy

PS: and yes, stubbies and flanges and CV's are all 6-bolt ...

Andy, your avatar looks weird. Did you have some work done?


Oh, and cool suspension stuffs.

yeah, i spent about an hour in front of two mirrors with a clipper and razor blades trying to get the hawk straight and centered ...

not perfect but gud enough for me ...
Andy

If you decide to sell those other parts, I think those spacers I made for you will need to be trimmed down a bit hieght wise....

Kind of look like Sting when he was young, like in Quadraphenia, but without the

mohawk.

I like the upgrades, looks bada$$.

Actually, Mike they were about 0.25mm too short. Completely usable (IMHO), but visibly short. Not your fault, mostly Andy's. We need to buy that guy a digital caliper.

dragging up the old posts here ... which 944 cv joint did you use ? 944 s2 turbo ? are they all the same ?

thanks

No turbo, just yer plain old 944 ...

Very nice Andy. Have you had a failure in the past or was this a proactive move on your part?

Tony

I wanted real 5-lug in the rear, not re-drilled hubs.

The slightly larger CVs were an added bonus.

FYI
Last time I was by Garold Shaffer's house he had about 20- 110mm 915 output flanges and 911 stub axles

thanks - am specifically interested in the outboard side - the setup I have on the shelf is 110 mm (I think) stub axle.
I have one of these on the shelf too of which the CV joint fits the stub axle ...
my plan was to have made an axle with 911 on one end and suby DOJ on the inside.

...you probably have a 108mm CV on the outside. You will need the 5-lug early 911 hub as previously mentioned as well.

Tony

Andy, what did you do with your rear brakes?

Me too - I'll be following this thread with great interest!

Andy do you have a 901 or 915 I did that conversion and finding the 911 stub axle which slides right into the 901 was difficult. HC

I went with vented rotors and Boxster brakes, neither of which has anything to do with the axles ...

Stock 901, the coarse stub axles are somewhat rare but not impossible to find.

yep - I have the matching pair of suspension arm hubs, including the 5mm spacer required from Patrick motorsports.
I bought a single 930 turbo axle - has the same CV's as far as I can tell on either side (inner and outer).
I pressed off the cv joints (didn't need much pressure) from the shaft and have bolted them up to the inner side of the hub - all seems to fit ok ...

Sorry.

Thinking ahead...
