I'm trying to fit a new airbag to the old strut, managed to get the big nut from the top undone by cutting old bag and putting damper shaft in vice, with protection,. any idea how i can tighten the nut up when the new airbag is in place.

Does this help ?

the problem is the whole shaft spins as you tighten the nut.

Is there not an allen key hole in the top of the shaft?

I can’t find the answer in the WM, but 90Nm is pretty tight, so it surely locks with a peg or similar?

There is an allen key hole on top of the shaft but the problem is then getting a socket on.

Use a ring spanner to hold the nut and a torque wrench on a hex socket.

Don't think the hex would be able to take 90Nm of force it would strip the corners off.

I've loosened then re-tightened mine with a ring spanner and an Allen key, checking that the nuts were tight.

All done, put the allen key socket in a vice then tightend nut with ring spanner. thanks for all the help.
