Do I have to replace the whole spindle ?

What is your question?

Do I have to replace THE WHOLE SPINDLE to a front wheel, to just replace the front wheel bearings.... for a 1993 Ford Thunderbird 3.8L LX ! ? ! ? What is the size socket (probably metric) to remove the center spindle nut... which appears to be not a solid piece but segmented...anyone know where the procedure to this nut removal might be? Thanks.
