* Wheel bearing press: This is arguably the most important. It's used to carefully press the old bearing out and the new one in without damaging the hub assembly or the new bearing. Trying to do this with a hammer and punch is strongly discouraged.
* Hub nut socket: The hub nut is usually very large and requires a specialized socket.
* Bearing race installer/remover: While sometimes you can get away without this, it's highly recommended for safely removing and installing the inner and outer bearing races. Improper installation can lead to bearing failure.
* Torque wrench: Essential for tightening the hub nut to the manufacturer's specified torque. Incorrect torque can damage the bearing or lead to premature failure.
* Possibly a slide hammer: This can be useful for removing some components, especially if they are stubborn.
While some very experienced mechanics might be able to improvise, attempting a wheel bearing replacement on a vehicle like a Silverado without these tools significantly increases the risk of damaging the hub assembly, the new bearing, or even injuring yourself. The cost of these tools (especially a good press) can be significant, but the potential cost of a botched job far outweighs it. Consider whether the cost of having a professional do it is less than risking damage and the time involved in acquiring and learning to use the tools correctly.
