How do I replace the wheel bearing hub assembly on 2000 Buick Lesabre? Any special tools required?

I purchased the parts new online to save about $800, and am having trouble finding a mechanic to do the job. They all want me to purchase the parts from them. I am somewhat mechanically inclined, but could use some guidance before I dive in and do it myself. Thanks.How do I replace the wheel bearing hub assembly on 2000 Buick Lesabre?
