It was extremely easy. I was expecting a rough DIY, but I didn't even need a hammer. You take the wheel off, then the drum (just the drum, you don't have to take your brakes apart at all) you undo the safety notch on the nut and then remove the nut.

I do recommend that you use an impact wrench, air or electric. I used and electric, not very powerfull, yet it took the nut off in less than a second. After removing the nut, the wheel bearing assembly simply, really simply, just slid out. I was amazed for such an important part was so easy to remove.

I used a the impact wrench tool tighten the bolt almost to where it was, the I used the torque wrench to finish it.
