Applied chisel and hammer to hub dustcap and pried it off.
Applied 36mm socket and 18" breaker bar to hub nut and then stand on bar to crack the nut.
So far, so good.
Remove remains of old backing plate - also simple.
Use the bolt removers to extract the old backing plate bolts and put a pound coin in the swear box.
At this point it all went horribly wrong.
The backing plates, which are allegedly correct for an ABS-equipped car, don't fit. Put another pound in the swear box.
Re-fit the hub to the stub axle, and discover that it will not rotate at all. The hub bearing has collapsed, thereby preventing the hub from turning. Much industrial language, albeit under my breath, follows. Empty wallet into swear box.
Re-assemble front end, have a brew and couple of biscuits and give up for the day.

You should be able to reassemble the hub bearing, i've had to do that a few times - find the right spot and they go back with no pressure, wrong spot and no amount of pressure will get the inner races back in!

Then hold them together while refitting on the stub axle. Use a long tube to push the inner race onto the stub, nothing else or you risk popping them out again.
