Ford Focus Mk1 1.4 16v Zetec 3dr

Any one no what size the hub nut is?

I'm geussing it will be 30 or 32 and are the front and rears same size?

One more i got front passenger wheel bearing gone if i keep driving it (The noise is very loud when driving and when car is jacked up and wheel is spun) could the wheel lock up??? People says it does and others say it don't

Thanks Joe
