Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, mechanic's stethoscope, torque wrench.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Lift the Vehicle

Use the jack to lift the front or rear of the Highlander, depending on which bearing is suspected.
Secure the vehicle with jack stands.

3. Remove the Wheel

Use the lug wrench to loosen and remove the lug nuts.
Carefully take off the wheel and set it aside.

4. Inspect the Wheel Bearing

Sub-step 1: Check for play by gripping the hub and rocking it back and forth. If there is excess play, the bearing may need replacement.
Sub-step 2: Inspect the bearing seal for any leaks or damage.
Sub-step 3: Spin the hub by hand and listen for any grinding noises.

5. Replace the Wheel Bearing (if needed)

Sub-step 1: Remove the brake caliper and rotor for access to the hub.
Sub-step 2: Unbolt the hub assembly from the steering knuckle (typically requires a socket set).
Sub-step 3: Remove the old bearing using a bearing puller.
Sub-step 4: Install the new bearing and reassemble the hub, rotor, and caliper.
Sub-step 5: Torque all bolts to the manufacturer's specifications (refer to the service manual for exact torque values).

6. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and then torque the lug nuts to the specified value.
