Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, mechanic’s stethoscope, torque wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.

2. Remove the Wheel Bearing Assembly

Sub-steps:
1. Disconnect the brake caliper and hang it aside (do not let it dangle on the brake line).
2. Remove the brake rotor.
3. Remove any retaining clips and bolts securing the wheel bearing assembly.
4. Carefully slide the wheel bearing assembly out of the hub.

3. Inspect and Replace the Wheel Bearing

Sub-steps:
1. Inspect the old bearing for damage, such as pitting or roughness.
2. If the bearing is worn, press out the old bearing from the hub using a bearing press.
3. Clean the hub area thoroughly to remove any debris.
4. Press the new wheel bearing into the hub, ensuring it is seated properly.

4. Reassemble Components

Sub-steps:
1. Reinstall the wheel bearing assembly into the hub.
2. Secure it with the appropriate bolts, tightening to the manufacturer’s specified torque.
3. Reinstall the brake rotor and caliper.
4. Reattach the wheel and hand-tighten the lug nuts.

5. Lower the Vehicle and Finalize

Sub-steps:
1. Lower the vehicle to the ground and torque the lug nuts to the specified value.
2. Test the brakes before taking the vehicle for a road test.
