Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure; engage the parking brake.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench.
Sub-steps:
1. Check tire pressures and inflate to the manufacturer's specifications.
2. Remove the wheel covers if applicable, and loosen the lug nuts slightly.
3. Jack up the vehicle and secure it with jack stands.
4. Remove the lug nuts and take off the wheels.
5. Inspect tires for bulges, punctures, or uneven wear; replace if necessary.

3. Suspension Component Inspection and Repair

Tools Required: Wrench set, socket set, torque wrench.
Sub-steps:
1. Inspect shocks and struts for leaks and damage; replace if they show signs of wear.
2. Check control arms and bushings for cracks or excessive play; replace as needed.
3. Tighten any loose bolts or nuts to the manufacturer’s specified torque settings.

4. Wheel Bearing Inspection and Replacement

Tools Required: Bearing puller, grease, torque wrench.
Sub-steps:
1. Remove the wheel and brake caliper to access the hub assembly.
2. Inspect the wheel bearings for wear; if they are noisy or rough, they need to be replaced.
3. Remove the old bearings and replace them with new ones, ensuring proper lubrication.
4. Reassemble the hub and caliper, tightening all components to specified torque values.
