It is a messy job. I'd have 1-2 rolls of paper towels and a fresh box of latex gloves. I pressure washed the knuckles before I started. I hate working through dirt and grease.
I used a brass drift and hammer to hit the studs and loosen the cone washers to pull the hubs off. It can take a few strong hits to dislodge them.
Besides the large socket for the adjusting nuts you'll need something to measure the preload when tightening the adjusting nuts. I used a small hanging scale.
Here's a link to a decent walk through. Goes well with the video SkaWAdoosh provided:http://www.off-road.com/trucks-4x4/tech/toyota-4x4-front-wheel-bearing-servicingreplacement-18322.html
He mentions tightening the adjusting nut, rotating the hub several times clock-wise/counter clock-wise, backing off and retightening,rotating, etc.
It's a very good point. And especially when seating in new bearings.
