[Healeys] Rear Axle Nut

[britishcars at shaw.ca (PG)]

I'm trying to remove an axle nut so as to replace the seals and bearings.

 

I have a 2 3/8" socket and try as I might, I can't get the nut to turn.  In
fact, I've damaged the but a little trying and I'm worried about rounding
the nut and being really screwed.

 

I don't understand why it would be so tight or difficult to take off.  

 

Any ideas
