Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, wheel bearing puller, grease gun, shop manual for specifications.
Safety Warnings: Always ensure the vehicle is on a flat surface and use jack stands to secure the vehicle after lifting. Wear safety glasses and gloves to protect yourself.

2. Remove Wheel

Loosen the lug nuts using a lug wrench.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Wheel Bearing

Locate the wheel bearing hub assembly attached to the wheel hub.
Check for any visible damage, such as rust or pitting on the bearing surface.
Spin the hub by hand to ensure it rotates smoothly without any grinding or resistance.

4. Replace Bearing (if necessary)

Remove the axle nut using a socket set.
Disconnect any brake lines or sensors if obstructed.
Use a wheel bearing puller to carefully remove the old bearing from the hub assembly.
Clean the hub assembly and apply new grease to the new bearing.
Install the new wheel bearing into the hub assembly using the puller.
Reattach the axle nut and torque it to the manufacturer’s specifications (typically around 150-180 ft-lbs for Highlander).

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands.
Torque the lug nuts to the specified value (usually around 80 ft-lbs).
Test drive the vehicle to ensure the noise or vibration has been resolved.
