2. Inspect and Tighten Suspension Components

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access suspension components.
3. Check the strut mounts, sway bar links, and control arm bushings for wear.
4. Use a torque wrench to tighten any loose bolts to manufacturer specifications (check service manual for torque values).

3. Replace Worn Components

Sub-steps:
1. If any components (e.g., struts, bushings) are damaged, remove them using appropriate socket sizes.
2. Install new components, ensuring proper alignment and fitting.
3. Torque new bolts to manufacturer specifications.

4. Reassemble and Lower Vehicle
