Backing out of the drive at the office on Xmas eve I heard a loud snapping sound from the right rear of the car. I managed to move the car forward a few meters and heard another snap though not as loud and decided that I probably shouldn’t try to continue without checking out the source of the noises.

Got underneath and found the outer, righthand side CV had come completely loose but with all six of the bolts still there.

Got it home on a flat bed, up the jack stands and dropped the axle to find 2 of the bolts had snapped off but only one of them with the broken end still in the drive flange.

Checked the other threads in the drive flange for damage and other than the one that has a piece of the bolt in it, one other thread is damaged. There is also a small burr on the recess in the drive flange where the paper gasket mounts between it and the CV.

I’m pretty sure the drive flange can be repaired but wanted confirmation on the removal procedure.

If I undo the big castle nut on the stub axle should I be able to drift the drive flange out through the back of the trailing arm and is re-intallation the drive flange the reverse?

Stubs are 911 5 lug and the drive flange is 6 bolt. I also have a spacer between the CV and the drive flange. The spacer is the outer ring of a CV and compensates for the difference between using the original 914 driveshafts.

I’ll post some pics later which should help. Thanks.

Thanks for all the replies and advice, I’m off the jack stands and back on the road.

It was a lot easier than I thought would be. The hardest part was making the paper gasket accurately! The only other problem was lining up the bolt holes in the flange to the bolts in the CV. After frigging around for about an hour trying to get one in I had a brain wave and put the jack under the trailing arm and pumped it till the driveshaft was level and bingo it was buttoned up in minutes.

Thanks again.
