Solution

1. Preparation

Gather tools and park the vehicle on a flat surface.
Ensure the vehicle is securely lifted using jack stands.
Tools required: Jack, jack stands, socket set, torque wrench.

2. Inspect Suspension Components

Sub-steps:
- Remove the wheel to access the suspension components.
- Inspect struts and shocks for leaks, dents, or cracks.
- Check control arms and bushings for wear or deterioration.
- Tighten any loose bolts to manufacturer specifications.

3. Replace Worn Components

Sub-steps:
- If any components are found to be faulty, remove the affected parts:
  - For struts, disconnect the upper mounting bolts and lower mounting bolts using a socket set.
  - For control arms, remove the bolts securing them to the frame and the wheel hub.
- Install new components in reverse order of removal.
- Use a torque wrench to tighten all bolts to the specified torque values found in the service manual.

4. Reassemble and Test
