Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the vehicle is in a safe working environment.

2. Tire Inspection and Adjustment

Sub-steps:
1. Check Tire Pressure:
  - Use a tire pressure gauge to measure each tire's pressure.
  - Inflate or deflate tires to match the recommended pressure (usually found on the driver's door jamb).
2. Inspect Tires:
  - Look for any visible damage, including cuts, bulges, or excessive wear.
  - Replace tires if any damage is found or if tread depth is below the recommended level.

3. Suspension Component Inspection

Sub-steps:
1. Visual Inspection:
  - Raise the vehicle using a jack and secure it with jack stands.
  - Inspect shock absorbers and struts for signs of oil leakage.
2. Damping Test:
  - Push down on each corner of the car and release; check for excessive bouncing.
  - If the vehicle bounces more than twice, replace the shocks/struts.

4. Wheel Alignment Adjustment

Sub-steps:
1. Check Alignment Settings:
  - Use an alignment tool to check the camber, caster, and toe settings.
2. Adjust if Necessary:
  - If misaligned, adjust the settings according to the manufacturer's specifications.
