I got down to the part where you start using the J 28733-B and got scared.
They don't tell you to remove the 3 bolts that hold the bearing/hub on.
When and how do I remove these bolts and are they ones they must be replaced?

The step after installing the special tool involves removing the three bolts. GM recommends replacing the bolts, but it is perfectly fine to reuse them if you apply some loctite to them.

Good to know about the loctite.
The step after install but not using the tool?
How to I get at the bolts I cant get a tool behind the thing the hub is mounted to.
The only thing I can think of is to disconnect it from the shock while using to tool and to comply remove the entire assembly that's shone in the last image you have.

Use a long handle 3/8 ratchet with a 3" extension and a 13mm 6point shallow socket.
