I think my transmission just exploded.

Have you thought about replacing just the CV joints and not the axles?

[Kroggers]

Yes I have, but as the axles are now rather old (30+ years), and have some rust on them I fancy replacing all of it for new.

I did make a note when I reconditioned them last time that I would replace them some time in the near future as they were starting to look old - looks like that time has come

[Kroggers]

Any one traveling over to Europe some time soon and fancy bringing two axles in their bag for me

CV joints are either good or they are not. I am assuming you are repacking and reassembling the old units until you replace them. If you get them together and they are silent, they will be good indefinitely.

Replace the faulty bolts and make sure you torque everything to spec. No need to throw the baby out with the bath water.

Hi Daniel, I will assume based on your posting that you have not read threw the complete discussion...

I already have Stage8 locking bolts on order. They should have been here by now and will have prevented this from happening, but they have been delayed.

I will patch things up to get to a already booked corner weight and alignment session on Thursday. With two small children and a full-time job, I do not have time to remove the axle, clean it all up and pack the CV joints again before Thursday + the centre where I am booked in has a VERY long lead time, and I want the alignment done asap.

The CV joints and the axles are old. When I last did the CV joints, there was substantial rust and corrosion on the axles - enough for me to decide I would change them soon. The CV's were also starting to show their age, but I decided to try and get at least one or two more seasons use out of them.

I am using this as a reason to install new axles with Stage8 bolts. I will probably clean up the old ones and keep as spare...

Interesting thread.
I will be replacing the CV bolts soon in my '80 SC.
Where do I get the Stage8 bolts you will be using?
Thanks in advance.

Where are you located - US or Europe?

I replaced all four rubber boots last Summer and installed new bolts from our host but after reading this post i'll put the odds on my side ... lol

Cheers !

What are the torque specs for the axle bolts?

[James Brown]

M-8 30 ft/lbs, M0-10 60 ft/lbs. For a 78-83SC.

[dpitman9]

I am in Florida, USA
Also, what advantage do the Series8 offer?
Thanks

[Kroggers]

As our host does not stock these, I am sure it is OK to list suppliers?

In the US, you can get these from here, and in Europe from me.

The benefit of the Stage8 bolts is that they integrate a locking system that prevents the bolts from backing out once installed, like this -

[dpitman9]

Got it !
Thanks very much for prompt reply.

If new CV joints are properly serviced and maintained (like....once per year cleaned and inspected and repacked using high quality hign pressure moly grease), then I'd guess they could last a LONG time. But unfortunately, most joints have not been properly serviced. I've looked at a fair number of CV joints from 911's, and they are rarely in the condition I would call "excellent." I'm not sure I've ever seen one in that condition. I've seen a few "decent/useable" condition ones, and a LOT of "unacceptable" ones. Very few "good" or "excellent."

I know that, and you know that. But the Porsche dealer in Stockholm would like us to think different...

Agree 100%, and mine were usable the last time I serviced them.

My new axles arrived today

[Kroggers]

Took some time during lunch today to have a closer look at my new axles. In all, they look nice and new and shiny, but I was not 100% happy with the way they had been packed up for shipping.

There was just some paper used at each end, and that was not good enough to keep them in place, so when I opened the boxes, the covers had come off the CV joints and there was grease everywhere



I gave them a good clean and inspected them for damage. They look good and ready for installation...

But I have one question, and I have had the same problem the other times I have installed the axles - how in hell do you install these and make sure every bolt is clean and has no grease on them

I am not really willing to clean the CV joint holes with anything as I do not want to contaminate the grease in the CV - so there is no real way to make sure there is NO grease in the mounting holes (especial now after the crap packing done by the factory!!!

[DW SD]

I would spray the bolt, once penetrated the CV with brake cleaner. Use a rag to make sure it doesn't mix with the grease.

Doug

[Kroggers]

I am sorry Doug, I am having problems visualizing you suggestion. Could you elaborate a bit further?

[Kroggers]

I actually have one more question. When I look closer at the new axles, I noticed that one of them is not the same as the other one - they both have the same part number, but on one of the axles one CV has s different end with a gasket already installed into a slight recess, which is not on any of the other ends.

What is this all about





These axles are to go on my 1978 SC, is one of the not correct? I have also received 4 gaskets separately in a bag. If the end of the CV does not have a grove in it, should the gasket still be used?

It is such a long time since I had my other axles off the car I can not remember what they look like - I do know I had to use gaskets to install them!

[pete3799]

What i did was install the axle and all bolts (just snug them up for now) then remove them one at a time, spray some blake clean in the hole, clean the bolts and reassemble.
The gaskets should fit in the wheel/trans. flange and also between the CV boot and CV.
