Hello,
While trying to remove the rear brake (I have an S2 so drums), I tried to unlock the big 41mm nut with a long ratchet, I heard a loud CLICK and since, the nut is moving but not coming out...
Should have used a blowtorch I know
is it possible that I broke the thread ?
it's the rear-left, so I think I should buy a new hub... is it from a Sierra ?
Thanks

Sorry to hear that. Using a blow torch would not have been a good idea at all, never heat a heat treated item (the shaft) unless you really know what you are doing. You say the nut is turning. Is it only the nut? Is the shaft staying still? Is the brake drum held tight so it wont turn?
If it just the nut turning then it looks like stripped threads, in which case cut the nut off carefully (using an angle grinder with a cutting disc if you can and then careful use of a chisel to split the nut). See if the nut thread has gone and the shaft thread is OK, if so a new nut is probably all you need.
If the drum is turning then a bar carefully positioned against two studs and the ground should hold it.
I have to say however that I wouldnt expect a thread to go with a sharp sound.
Let us know what you find.

Thanks for your answers.
How did you removed the drum hub on your cars ?
My nut was blocked and my handbrake is not tight enough...
So I used the spare wheel (it has a hole big enough to allow the socket to be inserted), so wheel on the ground, with a short ratchet, I was making the wheel roll ! (Our cars are quite light, I am not that strong ! ) so with a long bar I could un-bolt it slowly (until the big CLIC).
So now, nut is loose and the shaft is still (made a mark on it , turn and the mark is still at the same place)
Of course I looked at the thread to see how to turn the nut (a friend warned me about this could be a left or right)...
I think I will try to cut the nut carefully and hope for the thread to be intact and if not, hopefully a new one should not be that expensive ?

This is a very big nut with a high torque setting. It is quite usual for the nut to be on so tight that the brake, even with the wheel on the ground, will not hold it. It is common to have to put a big bar across studs to hold it, you ought to get ready to do that when you put it back.
It does sound like the nut thread has stripped. If the shaft is still but the nut is turning then it cannot really be anything else. Cut it off carefully and look at the threads, see if it is the nut thread (likely) or the shaft thread (unlikely) then I suggest you report back.

There is no need to undo the hub nut to remove the brake drum.The drum should pull off as long as the brakes are not binding.
( Sometimes a heavy rubber or hide mallet can help it on its way.
)
I can't tell you the full story, it would make you laugh for years...

Go on ! It's a Friday, we could do with a laugh.
If it makes you feel better I spent several hours trying to get the rear drums off my old VW...then realised I left the handbrake on. Felt pretty stupid.
Hello all, totally forgot to follow my thread, sorry :/ If it makes you feel better I spent several hours trying to get the rear drums off my old VW...then realised I left the handbrake on. Felt pretty stupid.
So here it is for the good laugh:
I decided to change the rear drums brakes and so, looking at the thing (not even reading in Steve's bible), "okay let's un-bolt it"
Measuring the size of the nut with a ribbon (any foot slide available), 40mm okay ! let's go buy a 40mm socket !
visiting 5 stores "40 mm ? that's and odd size"
... Finally ordering a 40mm socket online, about 10£ and 7 days after trying to unbolt it, good guess, everybody knows it's a 41mm nut
Re-buying a new socket (keeping the other as a souvenir to prevent me from being too confident) 41mm pretty standard and easy to find.
Trying to unbolt, impossible (torque of this is 350 Nm for the recall), wheel was even moving with the car on the ground... I found a big spanner, CLIC "yeaaah", and shortly after, the spanner broke down (Facom tools are not solid anymore), finally found a longer spanner and victory! : now the nut is loose, you know the rest...
So I broke my car by trying to unbolt something perfectly fine, buying 2 useless sockets to perform this.
All I wanted to do was change the drums pads, which do not require to unbolt anything except the wheel...
You can mock me
Actually I am trying, opened a new thread here :

best thing to do would be to cut the nut and see if the shaft is damaged, but my car cannot stay not movable where it stays right now...
So i plan to order the whole part if I can find one and only replace what's broken and send the rest back or keep it as spare...

You need a big version of this

They work really well
The nut is fairly easy to source - ford garages used to have them not sure if they still will - you are supposed to fit a new nut when replacing the wheel bearing - some kits came with the nut.
Just had a quick look - loads on ebay.
Note early sierras had all right hand nuts, later had left and right. I can't remember which went where so won't comment. Presumably they changed when they lost a few wheels
