> Inner cv came completely off of the trans output flange, a mile or so from home.

Just when you get the thing running great... bam! CV joint comes off! Completely seperated from the trans output flange. I rolled it all the way home to just around the corner from my house. Shar helped me push it from there to the street in front of the driveway. Danny's due over in a few and together with help from my youngest son and Shar, we can get it up the driveway and onto the side of the house.

I got lucky in that the shaft just fell down on top of the HE and didn't do any damage. Pics later...

Did the joint actually fall off, or did the axle fall off? How? Did someone not torque the bolts?

Repeat after me: "New bolts, new washers, proper torque." As the crush on the gaskets has been questioned as a potential problem, you have my permission to clean the jount and flange up and use a bead of RTV instead. The Cap'n

Back in 1971 I did a clutch job on my 67 911S. I forgot to torque the cv joint bolts properly. It was a long time until someone came along out in the open country of West Texas. The old cowboy reminded me I was driving on of those "furen" cars.

But I will be tomorrow...

I've got parts, thanks for the offers. I have a set of Dr. Evil's drilled CV bolts around here somewhere too. I wsa planning to save those for the /6 though.

Like I said, the joint separated form the trans output flange. It would appear that all of the bolts came loose. And I've never taken them off since I've owned the car. The holes don't appear to be stripped, but I haven't gotten a good look yet. I'll do that tomorrow. When I get under it...

Seriously when is your luck gonna change? Let me know if you need anything. If they output flange is hosed, let me know, I'll go you know where and see if I can work my magic to get one cheap.

DOH! You have developed the fecal touch. Everything you touch turns to shit (IMG:style_emoticons/default/wink.gif)

You can reuse my bolts dude, no need to wait on a /6 transplant. (IMG:style_emoticons/default/rolleyes.gif)

If you need a flange I am sure I have one.

CV failure is a rite of passage for the 914 owner. It happened to me twice, and then I safety wired them on and it hasn't happened since. (IMG:style_emoticons/default/biggrin.gif)

I have NEVER had a CV bolt that I've installed EVER come loose or off. Only once have I safety wired a set of CV bolts, and only then because the fool was willing to part with an obscene amount of money. I buy a LOT of CV washers. Many of the cars we service at the shop don't even use washers, BTW, and they STILL don't come off. The Cap'n

I am in agreement with the Capt'n. If you put the CV bolts in with the proper backing plates, the proper schnorr washers and use the proper torque spec they will stay on.


I tried all sorts of fixes for this over the years, then I went to the book and followed the directions of the engineers. Thems some smart guys.. (IMG:style_emoticons/default/smile.gif)

Just for reference, what is the torque spec?

Preliminary investigation by just reaching under the car with a bolt and trying the holes indicates that the output flange may have two bolt holes that are stripped. At least the bolt won't start in two holes.

I'm going to have to do the "move everything out of the garage" thing so I can use the lift. I'm still not ready to use jackstands just yet. I'll put the joint back on with the two good bolts and roll pins so that I can run the car enough to get it up my steep driveway.

You do realize that two of your holes are for roll pins and not for bolts?
