2000 Altima front bearings

Hello ..
I have a vibration problem that I think in the left front bearing.
Has any one done the bearing replacement themselves ?
I need a diagram of the wheel & shaft so I can figure out what needs to come off to get to the bearing. Does any know the part number also?
Any advice will be greatly appreciated. I have done the front bearings on a Mazda Miata but that is rear wheel drive.
I am new to the front wheeel drive cars.
Thanks in advance
