Once I tried finding some locally sourced cv joint bolts (for my 5-speed, after realizing after tearing into a suspension servicing project that some of the original ones that came with the car were buggared up by the previous mechanic) and the best I could locally source were a lower grade steel, in stock at a local independent auto mechanic. Those lower grade steel cv bolts (I think they may have been grade 10.9) could not take the full Porsche torque specs before yielding. New ones of the proper grade (12.9 grade, for the 5-speed bolts) could take the full torque, so these things really do get torqued right up to their yield point, and that's also probably why Porsche recommends replacing them with new each time. With proper torque, you won't need to use thread locking compound. Really sorry to hear about this issue; best of luck fixing!
