Solution

1. Preparation

Gather necessary tools: jack, jack stands, wrench set, and a flashlight.
Park the vehicle on a flat, level surface and engage the parking brake.

2. Visual Inspection

Sub-steps:
1. Open the hood and visually inspect the strut assemblies for any signs of oil leakage.
2. Check the mounting points for rust or corrosion.
3. Look for any cracks or damage on the strut body.

3. Bounce Test

Sub-steps:
1. Stand at the corner of the vehicle and push down firmly on the bumper.
2. Release and observe the strut; it should rebound once and settle back to its original position.
3. If the vehicle continues to bounce multiple times, the struts may be worn out.

4. Noise Inspection

Sub-steps:
1. Drive the vehicle over bumps or rough surfaces.
2. Listen for any unusual noises from the strut area (clunks or rattles).
3. If noises are present, it may indicate a problem with the strut mounts or the strut itself.
