Another possibility, remove the wheel, brake caliper and disc assembly, open half shaft nut and remove spindle, bring to auto machine shop let them press in and out the bearing then reassemble.
There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate

yes. there is a big nut around 32 mm that has to be loosened. it is torqued at about 180 ft lbs.

once the hub is removed, the bearing has to be pressed off and on. best left to a shop to do this for you.

it takes a shop around 2 hours for this operation.

You do need special tools and if you do not want to purchase them then let a shop do this.
