There have been several near misses on S cars, myself included!
First lesson, NEVER use the star bit bolts. (those joints are now supplied with 12 point star socket heads). Those are designed for speed in manufacture by robotic machines which load them axially and at precise torque. They are not designed for taking out again or for hand fitting!! I did manage to get mine out using an impact driver (the hand hammer type not electric).

Take the trouble to source Unbrako 12.9 hex socket head bolts in the web. I would not now trust anything else now. And then use an Unbrako or similar quality allen key. They are supposed to be 32 ft lb (43Nm) which isnt that easy to get with the space available, so it is an Allen key with tube job! Clean threads and loctite! I haven't wired mine but I have paint marked them and do check them.

Thanks for the advice Richard but I've stuck with the Torx bolts..



My 18V impact driver comfortably delivers 32 ft lb plus lots of thread lock plus lock wire so I think I'll be OK.

Back on four wheels at last.

There was nothing wrong with the bolts it was just my driving.

Actually I only drove it down the hill.

It was something to do with the quality of the inferior replacement cv joints and we found out afterwards that the inner bolts have a different tread (on the Griff anyway) to the outer ones. Probably to do with the obscure diff from a Maserati. On the plus side we got 38 to the gallon on the way back, not bad for a V8.
