* Wheel bearing press/puller: This is often the most crucial tool. It's designed to safely press the new bearing into place and remove the old one without damaging the bearing or hub assembly. Improper removal or installation can easily ruin a new bearing. A generic press might work, but vehicle-specific adapters are often needed for optimal fit.
* Torque wrench: Essential for tightening the axle nut or other fasteners to the manufacturer's specified torque. Over-tightening can damage the bearing or axle, while under-tightening can lead to premature failure.
* Hub nut socket: The size and type of socket needed to remove and tighten the axle nut can vary widely between vehicles. Some are standard sockets, others are special impact sockets designed for this high torque application.
* Bearing race installer/remover: Some vehicles require these tools for the inner and outer bearing races, depending on design.
* Other specialized tools: Depending on the design, you might need tools for removing the brake caliper, cotter pin removal, ABS sensor removal or other components before you can access the bearing.
In short: While you *might* be able to get away with basic tools on some older, simpler vehicles, it's highly recommended to have, at minimum, a wheel bearing press/puller and a torque wrench. Attempting the job without the proper tools significantly increases the risk of damaging components, leading to a more expensive repair later. Consider the cost of renting or borrowing these tools versus the potential cost of damaging parts. If you're not comfortable working on your car, it's always best to consult a professional mechanic.
