I had to get mine taken off by a man with an airgun, just on too tight and it's a strange shape nut.

From front to back mine is sprocket adapter, UJ, splined slider, UJ, centre bearing, rear UJ onto diff. Get Autoprop out near Crowborough to shorten it for you and weld on the splined slider.

If this isn't too late to be any help this is how I did it.

First, I locked the sprocket with a piece of ali between the teeth and the engine to hold it still, then I spent 3 hours with a three foot breaker bar and various sockets on different parts of the nut trying to loosen the thing while I stood on the engine to stop it going all over the garage floor. Finally after rounding off all the corners on the nut mild panic set in. I then put an open ended spanner, 5/8" AF I think, on the square end of the nut that the sensor uses to read the speed and hit it with a club hammer, two minutes later the nut was loose.

I had a similar problem, the material seems to be very soft, using a standard socket just rounded off the corners. I bought a deep impact socket which is a true full hexagon. After locking the sprocket it then came off easily.

Thanks guys in the end I just put it in gear used an open ended spanner and a club hammer and with 4 or 5 bashes it loosened
Thanks for all the advice
