Doc Gollum said I was insane to change the knuckle to replace a failed ABS sensor when I could so easily have whipped off the hub and popped in a new ABS sensor as in your guide. I acknowledged my error and agreed that my way I also had to reset camber and toe-in.

Would this reluctant inner race complicate the ABS job?

In a word .. yes ..

The ABS sensor lies behind the toothed section of the bearing hub, so to remove the sensor as in my guide you have to remove the hub/bearing .. if it fell apart like mine did it means a new hub/bearing which adds to the cost, and significantly to the time taken.

I, initially, thought the bearing failure may have been induced by the removal to allow the ABS sensor change ... but that was the other wheel ... so I still don't know why this bearing failed ... 

Nige, surely, if the bearing is being removed for ABS sensor replacement and the bearing is OK, the fact the bearing race stays in place matters not as you can get access to the ABS sensor with it still there?

Then refit the hub onto the race which is still present (as the inner race is a split race)

I see what you mean .. but I would have thought it was not good practice to refit a "split" bearing as it is not actually designed to come apart ??. There must be a high risk of some sort of contamination of either the ball race itself or the bearing surface which "might" lead to premature failure and require the job doing a "second" time ??

"If" I was doing the ABS sensor again (and I seriously hope never again) and the bearing split I would fit a new one....  but that's just me being over cautious perhaps ...

There certainly easy enough to take apart (you can probably pull the race from anew one).

I guess contamination is possible but, if your being careful then should not be a huge issue.

I suppose thinking about it this wouldn't be an issue if all u want is access to the abs sensor. Is there anybody out there who has removed a bearing hub assembly and then bolted it back on butted up against the old race that's stuck on the shaft?

I personally wouldn't. You're in there. Cut it. Chisel it. Remove race. Stick new bearing on.
