Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, wheel bearing puller, grease, and safety glasses.
Safety Warnings: Always ensure the vehicle is on a flat surface and securely supported on jack stands before working underneath.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and support it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Wheel Bearings

Inspect: Check the wheel bearing for signs of wear or damage. Look for rust, pitting, or abnormal play.
Remove Hub Assembly: If replacing, use a socket set to remove the bolts securing the hub assembly to the knuckle.
Use Wheel Bearing Puller: Employ a wheel bearing puller to extract the old bearing from the hub.
Clean and Grease: Clean the bearing housing and apply a suitable high-temperature grease to the new bearing.
Install New Bearing: Press the new bearing into the hub using the puller until it is seated properly.

4. Reassemble

Reattach Hub Assembly: Align the hub assembly with the knuckle and secure it with bolts, tightening to the manufacturer's specified torque.
Reattach Wheel: Place the wheel back on the hub, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to the manufacturer's specification.
