Thanks so far.
Here's the limited Withams description Land Rover Salisbury Front Axle Assembly 110HD/130 complete with Differential, Casing, disc brakes, Callipers etc. it came preserved and stamped with refurbished by Abro on a plate on top of diff casing.
Just checked and the axle has 24L00953 C stamped on the tube.
I have bought this item on fleabay http://www.ebay.ie/itm/271411595439 and took a chance on being able to do something with it. However on reflection I think I wasted my money and will instead refurbish it and sell it on.
As for needing a special tool, what was this used for? I am guessing it locks up the box so the retaining nut can be removed.
Blooming nightmare this has been :red:
