Hi Jon
Thanks for the heads up on the power steering. I will be paying close attention to this and will check it when I get a spare five minutes. Definately not something you want going wrong.
Me being me I kept hunting last night and came up with what it might be. I strongly suspect it is the wheel bearing. Going by what Wikipedia says.

I think the CV joint will need replacing too though as the gaiter is on its last legs and that will leed to further problems
