These specialized tools often include:
* A bearing race and seal puller: This is designed to grip the inner race of the bearing and pull it out without damaging the surrounding components. A generic puller might not have the right grip or reach.
* A hub nut socket: You'll need the correct size socket to remove the large nut holding the hub assembly onto the spindle. This is often a very large and specialized socket.
Trying to improvise with generic tools can easily damage the hub, spindle, or other parts of the suspension, resulting in more costly repairs. It's best to consult a repair manual for your specific Aztek model to see exactly what tools are recommended and to avoid damaging your vehicle. You can also search online for videos showing the process; seeing the tools used in action will give you a better idea of what you'll need.
In short, while you *might* get away with it with some ingenuity, using the proper puller(s) will significantly increase your chances of success and prevent damage.
