anyone have a parts diagram for a Nissan X-trail front hub?

story goes: friend was clamped and clampers damaged front wheel - friend drives over plank with nail - has puncture - AA man turns up and has to chisel off the stud which needs replacing.

Friend goes to dealer who says stud is a quid but labour will be £ 280 after looking at hub diagram saying there is something complicated about it.

I can't what more there is than removing 2 bolts for the brake caliper, the main hub nut and pulling of the hub.

what is the year and model of the Xtrail.

also the Xtrail uses a electric 4 wheel drive system, so it is most likely that there will be some dissasembly required for the hub to be taken out and have the stud replaced
