Could someone tell me the toque specs for the 3 bolts that connect flex disc to Transfer case output flange on a 09 E61? There are bunch of specs for that on BMW TIS which is confusing. Realoem shows hex nuts while mine are E-torx


thanks

 

Depending on your bolt size and thread pitch. You probably don't know the pitch, but what's the bolt size?

 

Have to check on that, remember using E12 socket on those.

Another question, do you have to really replace all those bolts that goes with flex disc? I know BMW says to replace every bolt even for non aluminum ones. Mine are super clean and no rust at all.
