Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, OBD-II scanner, torque wrench, inspection mirror.
Safety Warnings: Ensure the vehicle is on a flat surface and use jack stands for safety when raising the vehicle.

2. Inspect and Replace Wheel Bearings

Sub-steps:
1. Lift the vehicle and secure it with jack stands.
2. Remove the wheel using the lug wrench.
3. Inspect the wheel bearing for wear by checking for roughness or play.
4. If defective, remove the brake caliper and rotor to access the hub assembly.
5. Use a bearing puller to remove the old bearing and press in a new bearing.
6. Reassemble all components in reverse order, ensuring proper torque specifications (typically around 100 ft-lbs for lug nuts).

3. Replace Damaged Suspension Components

Sub-steps:
1. Inspect control arms and bushings for wear or cracking.
2. If damage is found, unbolt the affected components using appropriate sockets.
3. Replace with OEM or quality aftermarket parts.
4. Reassemble and torque all bolts to manufacturer specifications.

4. Alignment Check

Sub-steps:
1. After replacing components, take the vehicle to a professional alignment shop.
2. Ensure that the alignment is within the manufacturer's specifications.
