Hi all,

For the tightening of the Propshaft to the rear differential am I right in thinking this relates to tightening torque 4AZ?

If so, when on that page which is:

I assume I have the:

“ZNS screws and nuts, shiny zinc coating
All versions with universal or constant-velocity joint*

But there's 3 different e90 bolt sizes listed for an E90 and I have no idea how to differentiate one to the other, the propshaft simply has 3 E-torx and 3 bolts with nuts

Update:

It seems there are two ribbed torque specs on that list, one for the E90 and one for the E92 M3 so I'm pretty sure by ribbed teeth it means the E-torx bolts so that means the e torx from the donut to differential is 40nm+40 leaving the bolt and nut to figure out.

If I'm not mistaken, BMW frustratingly references the size of the shaft of a bolt and not the head? So M10 (10mm) isn't the size of the head we would put a socket or spanner on, it's the body size of the bolt.. Like what is the point

So back to the torque figures my nuts and bolts are either the M10-10.9 or the M12
