06 sierra 4x4 front wheel bearing removal

My dad has a 06 sierra 4x4 1500 with a bad front left wheel bearing assembly.

He is doing the job and wants to know if there is anything special (tools) that he will need to remove the hub/bearing assy?

Already have the 36mm socket, does he need a gear puller?

What Ft/Lbs torque is the axle nut?

Thank you

Ted
