I've put this off since August. The last thing on the car to do is to remove this hub nut to remove the driveshaft - I bought the car with drive shaft still stuck in the hub because the previous owner couldn't remove it. Three breaker bars broken, and a snap on breaker bar bent. This procedure nearly ripped the desk off the wall. Everything either bends or breaks: I've drilled out half of the hub nut, it just won't rotate around the shaft! What could possibly prevent this from coming off? I've tried everything!

It's not a left hand thread is it?
Try some heat
|

I may deserve a slap for asking, but have you got it hot?
|

Yes, oxyacetylene, air chisel, hammering, etc. It's not reverse thread either - it's a mystery. The solution is buying another strut, but would like to know what is holding this on following this much abuse?

Have you tried an 1" air gun?

I was going to suggest a beefy rattle gun. However, this may not be cheap or handy .

3/4 drive socket onto a breaker bar. Add 6ft of scaffold bar as a lever. Heat nut till seriously hot and then apply leverage
Last one I had like that I was rocking the car it was attached to before it gave way
|
|
If it can be fixed with a hammer, then it must be an electrical fault
|

Usually much easier to do these when it's all still attached to the car.
3/4" breaker bar and socket or a big rattler gun. If that won't do it, cut your losses and get another complete corner from a scrapper. When "picking my own" corners I always try and undo the hubnut before removing the rest from the car - it gives alot more to lever against.

It was attached to the car - one of the fellow garage owners borrowed a kit off the coach place up the road, the ones they use to remove nuts from trucks. As said 'we've tried everything'. I give up now, to the bin with you (after I've taken all the bits off ).

Can you not get the grinder in and chop a quarter of the nut off to reieve the pressure?
|
|
|
|
|
|
|
Have you considered splitting the nut with a cold chisel?
|

As said above, take it to a bus or truck workshop. A proper 1" drive gun will undo it.
Borrowing said 1" impact gun wont work unless you have an air line and compressor big enough to run it.

It was a 1" drive gun we tried. I can't fit anything (angle grinder) in the hole without destroying the hub. I've drilled 1/2 inch out of the hub nut in the hope that it would release some of the hold the nut has, but it made no difference - the nut is no longer six sided now, so there's not much I can do - struts are only about 20 - 30 quid anyway.

can't you drill down the other side of the nut too, so it comes away in 2 halves?
this worked for me on my VW T25 camper, those rear nuts are at 500Nm, which broke my 1/2" breaker bar, so drilled both sides of the nut, and hey presto!

Could you try a dremel type tool with a small cutting burr on to cut through the nut and relieve the pressure?
|
|
|
|

|

I tried with the dremel, but it was taking absolutely ages, and the space is too small to get it all the way in - a drill took quite a while as well. I might try doing the other side as well.

One way to go through a piece of steel like a nut in a timely abut controlled manner is with a carbide burr in a die grinder.

to get the max effort in the nut you need equal or more leverage restraining the hub itself
most successful way i do it is to refit the brake disk, bolt the disk to the hub using all 4 wheel bolts, refit caliper carrier, slip a stout screwdriver or allen key deep into the viens of the brake rotor, turn brake disk until that item is locked against the caliper carrier. then apply prodigious amounts of torque to the nut with the strut laid on the floor
