3. Inspect and Replace Damaged Steering Components

Sub-steps:
1. Lift the vehicle using a jack and support with jack stands.
2. Remove the front wheels to access the steering components.
3. Check tie rods and ball joints for play; replace any components that are worn or damaged.
  - Torque specifications: Follow the manufacturer’s specifications for tightening.

4. Examine and Replace CV Joints

Sub-steps:
1. Inspect CV joints for boot tears or grease leakage.
2. If damaged, remove the axle from the hub and transmission.
3. Replace with new CV joint or axle assembly as necessary, ensuring proper alignment and securing with the specified torque.

5. Inspect and Replace Wheel Bearings

Sub-steps:
1. Remove the brake caliper and rotor to access the wheel bearing.
