Replacing the wheel bearings on a 2002 Ford Explorer is crucial for maintaining vehicle safety and performance. This guide provides comprehensive information on the types of wheel bearings available, the replacement process, and essential tips for ensuring a successful installation.

Understanding Wheel Bearings

Wheel bearings are critical components that allow the wheels to rotate smoothly while supporting the weight of the vehicle. Over time, these bearings can wear out, leading to noise, vibration, or even complete failure. Signs of a failing wheel bearing may include:

  • Grinding or humming noises while driving
  • Vibrations felt in the steering wheel
  • Uneven tire wear

If you notice any of these symptoms, it’s essential to address them promptly to avoid further damage.

Types of Wheel Bearings for 2002 Ford Explorer

When replacing the wheel bearings in a 2002 Ford Explorer, you have several options:

  • Front Wheel Bearings: Typically available as individual pieces or as part of a hub assembly.
  • Rear Wheel Bearings: Similar to front bearings but may vary in design depending on whether they are for the driver or passenger side.

You can find various brands and price ranges at auto parts stores, with prices generally ranging from $22.39 to $227.99 depending on quality and type.

Replacement Process

Tools Needed

Before starting the replacement process, gather the following tools:

  • Socket set (including 14mm, 15mm, 18mm, 19mm, and 21mm sockets)
  • Torque wrench
  • Pry bar
  • Hammer
  • Copper anti-seize compound
  • Liquid thread locker

Steps to Replace Wheel Bearings

1. Lift the Vehicle: Use a jack to lift the vehicle and secure it with jack stands.

2. Remove the Wheel: Take off the lug nuts and remove the wheel to access the brake assembly.

3. Detach Brake Components: Remove the brake caliper and rotor. Ensure you hang the caliper securely to avoid damaging the brake line.

4. Remove Old Bearing:

- Locate and remove the bolts securing the wheel hub assembly.

- Carefully pull out the old bearing from the knuckle.

5. Clean and Prepare: Clean the mounting area where the new bearing will be installed. Apply copper anti-seize to prevent future corrosion.

6. Install New Bearing:

- Position the new bearing into place.

- Secure it with bolts and torque them to manufacturer specifications (typically around 83–84 foot-pounds).

7. Reassemble Components:

- Reinstall the rotor and brake caliper.

- Replace the wheel and torque the lug nuts.

8. Lower Vehicle: Remove jack stands and lower the vehicle back to ground level.

9. Final Torque Check: After lowering, perform a final torque check on all critical fasteners including axle nuts (typically around 184 foot-pounds).

Important Tips

  • Always use new hardware when installing wheel bearings to ensure proper fit and security.

  • Avoid using impact tools for final torquing; this can lead to improper preload settings which may cause premature bearing failure.

  • If you are unsure about any step in this process, consider consulting a professional mechanic.
