3. Check and Replace Wheel Bearings

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Remove the wheel and brake caliper to access the hub.
3. Inspect the wheel bearings for wear or noise; if they are damaged, remove the hub assembly.
4. Press out the old bearings and replace with new ones, ensuring proper greasing.
5. Reassemble the hub, caliper, and wheel, then lower the vehicle.

4. Alternator Inspection and Replacement

Sub-steps:
1. Disconnect the battery.
2. Remove the serpentine belt from the alternator.
