CV Joints, Available again? Options

[914Sixer]

Originally the early 911 CV's had 6 bolts. Then they changed to 4 and 2 roll pins on the large 108 stub axle. When they switched back to the 100mm axle they went to 6 8mm bolts. After that they went back to the larger 108 again with 6 10mm bolts. My guess is the extra clamping force is need from the 6 bolt application. The VW Thing, 411/412 and VW bus all used 6 bolt 8mm bolts. They all used 100mm CV's with different angles of departure.

Bloody hell!!! (IMG:style_emoticons/default/headbang.gif) I just went to pull the trigger on a pair of cv joints on the Sunset Porsche site and now those joints are listed at $150 apiece. Two months ago they were listed at $75. (IMG:style_emoticons/default/WTF.gif)

No comment. Clay will give me a time out.

Wait till next year.

I have decided I am just going to use lobro type 1 CVS and just machine the gasket area .. It will be pretty straight forward and fairly inexpensive..

[bbrock]

That's what I'm going to do now too, but as of two months ago, it would have been cheaper just to get the correct joint. I just don't understand what kind of games they are playing with these joints that are clearly still being made but they don't want to share.

[ChrisFoley]

I stopped offering modified Type 1 CVs precisely because of the availability of Porsche 914 axles and CVs. Now that they've skyrocketed in price I may have to reconsider.

I'd be down for a pair of joints.

just one person's experience

I put new type 1 joints (x4) on the racecar.
granted it might be an extreme environment
but with limited hours of use... 20?
I noticed much more wear than original joints

so this could be due to my application
but I am also harboring the belief that the type 1 (modified) joints do not hold up nearly as well as original specification joints used to.

I'm not a fan
I'm going to upgrade to 944 CV's and add real weight to the racecar in exchange for longevity.... and I hate adding weight!

I have the same opinion after about 4 years since replacement. MAYBE 10k Miles on them?

I haven't inspected them yet....just a mess I'd not get into at the moment.

@914 teener are those the ones I. sold you when I converted to Subaru? If so, they didn't have more than 600 miles on them, IIRC. (IMG:style_emoticons/default/beerchug.gif)

@bbrock the type 1 one joints are about $45 each..

I guess I was comparing the Genuine joints with the Lobro kits that include boots, bolts and other goodies; and then factoring in additional machining costs. Not exactly apples to apples comparison.

[ChrisFoley]

I was selling the modified Lobro T1 units (with boot, gasket & installation hardware) for $110 each, so not all that cheap compared with new 914 ones @ $150.
Quite a bit of work goes into making them fully compatible & easy to use.

Yes they are. I haven't inspected them yet. I may though if I keep the car for now.

Have a spare trans and I may swap it in if I don't sell the car and I'll do it then.

I've probably put those miles on them Kent since I got them from you. I'll assume they were Lobro's?

One thing for sure with the type 1's I've experienced is they will sling grease if you don't have the gasket recess that Foley used to sell. It is a real pain but I got mine to finally seal with some high temp silly cone. I had to clean the faces really well and when you bolt up the joint it is near impossible to keep the joint and the flange grease free when installing them.

AND if you use the gasket without the recess the bolts will back out.

So if I'd to go that way again I'd definitely get a set with the recess.

My two cents.

Now the price for Genuine Porsche is down to $134. Are these things tied to pork belly futures? (IMG:style_emoticons/default/WTF.gif)

Not quite that easy, the CV material is hard as hell. Might be easier to send it to a crank grinder and have them grind the recess in.

Sales would be my guess.. I am going to machine some of the Lobro type 1 in the next week or so.. Plan on using the 2 914 ones that I have that are good and the 2 lobro ones in the less stress area.. Now where would the least stress area be?? Ultimately I am sure I will end up with something else but for now this will be the best solution.

Yes. Yes, that is how they are priced.

Sorry Rob, I missed this earlier. Yes they are Lobro.

A sharp carbide tool bit will cut them just fine. The body is only moderately hard, and the ball track area is flame hardened.

Today I assembled driveshafts with four of the modified Type 1 joints that Chris
marketed in the past.
The modifications were done beautifully. They're going in my project car with a
fresh 2.0 6 cyl.
I hope the reports of early wear prove wrong.
Has anyone ordered or purchased the available 914 6 assemblies ?

[dr914@autoatlanta.com]

we are very lucky to have stripped so many 914s in years past that we have many many many many cvs that we can rebuild, so make them into ready to install axle assemblies. Makes it easy and non greasy for the mechanics
