A couple of points....

The wheel bearing might not be worn, it might have just gone "dry" and hence the noise and the grease at the back. In either case you need to renew it. You should also grease the splines.

The strut to hub bolts and nuts are special items - intended to locate the hub precisely so when you re-assemble it the geometry is not affected. Note that the nut has a locking surface on it so often it's easier to undo the bolt rather than the nut. I forget the sizes but the nut is bigger than the bolt - 18mm and 21mm I *think*.

Sticking bolts apart - changing the bearing is usually easy... Much easier than on the FoMoCo derived chassis.
