5. Reinstall the wheel and lower the vehicle.

4. Inspect and Replace Wheel Bearings

Sub-steps:
1. Remove the wheel and brake assembly to access the hub.
2. Use a pry bar to check for play in the wheel bearing.
3. If worn, remove the hub and replace the wheel bearing, ensuring proper seating.
4. Reassemble the brake assembly and wheel.

5. Inspect and Replace Suspension Components

Sub-steps:
1. Check control arms, bushings, and struts visually for any damage or excessive wear.
2. If any component is worn, remove it using appropriate tools and replace it with new parts.
3. Reassemble all components securely and ensure proper torque specifications are followed.
