I have no idea, but my strategy is to use safety wire to secure the bolts.

I've got the axles on the shelf but haven't installed them yet, though the bolts are drilled and ready to go.

Having read the various posts about the hassle of dropping the differential and snaking the axles out, my plan is to cut the axles off with an angle grinder, then they'll just slip right out without disturbing the diff. The two halves of the annular axles will then go in no problem.

I'll torque them by feel (or spec if known at the time) and then install the safety wire.

I'll document the installation with pics when done.

To put a couple of numbers to the concept of "feel":
If bolt threads are M10, torque = 70Nm.
If M12, 135Nm
Threads and under-surface of bolt head clean and oiled.

The FSM for the W126 shows 125-145 Nm for the Connecting Flange Bolts and 30 Nm for the Axle Shaft Flange (wheel end).

Also, put you model/year in your signature (user cp) to ensure you get correct information about your car specifically.
