Look for one hour labor to press the old one out of the hub and press the new one in (this is if you bring your hub in to a shop) plus the cost of a bearing (about $60.00...)
having it done is considerably more expensive.
Keep in mind that if you are going to pay anywhere close to $165.00 you can purchase a NEW OEM hub from Tousley Ford (steve) with a bearing already pre-pressed in it.. simply swap the old for the new at about 25 minutes of your time.
