Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, wheel chocks.
Raise the vehicle securely and support it with jack stands.
Remove the wheel using a lug wrench.

2. Remove the Wheel Hub Assembly

Remove the brake caliper and bracket (if necessary) by unbolting the caliper bolts.
Suspend the brake caliper using wire to avoid strain on the brake line.
Remove the rotor if it obstructs access to the wheel hub assembly.
Unfasten the wheel hub assembly retaining bolts. Use a socket set for this task.

3. Inspect and Replace Bearings

Pull the wheel hub assembly off the spindle. Inspect the inner and outer bearings for signs of wear, such as pitting or discoloration.
If bearings are damaged, clean the hub assembly and replace the bearings with new ones.
Use bearing grease to pack new bearings thoroughly.

4. Reassemble Components

Reattach the wheel hub assembly to the spindle and secure it with retaining bolts. Torque to manufacturer's specifications.
Reinstall the brake rotor and caliper, ensuring all bolts are tightened properly.
Reattach the wheel and tighten lug nuts in a crisscross pattern to the recommended torque.

5. Lower Vehicle and Test Drive

Remove jack stands and lower the vehicle to the ground.
Test drive the vehicle to ensure that the noise and vibration have been resolved.
