Solution

1. Preparation

Gather tools: tire pressure gauge, jack stands, impact wrench, torque wrench, wheel alignment tool.
Ensure the vehicle is on a flat surface and securely supported.

2. Tire Pressure Adjustment

Sub-steps:
1. Remove the valve cap from each tire.
2. Use a tire pressure gauge to check the pressure against the manufacturer’s specifications (typically found on the driver’s side door jamb).
3. Inflate or deflate tires to achieve the recommended pressure.
4. Replace valve caps securely.

3. Suspension Inspection and Replacement

Sub-steps:
1. Jack up the vehicle and secure it with jack stands.
2. Inspect shock absorbers for leaks; replace if found defective.
  - Use an impact wrench to remove the bolts securing the shock absorber.
  - Install the new shock absorber by reversing the removal process and torqueing bolts to manufacturer specifications (refer to service manual for torque values).
3. Check coil springs for fractures or sagging; replace if necessary.
  - Remove the lower control arm bolts and disconnect the coil spring using a spring compressor.
  - Install the new coil spring, ensuring it’s seated correctly.

4. Wheel Alignment

Sub-steps:
1. After any suspension work, perform a four-wheel alignment.
2. Use a wheel alignment tool to adjust the camber, caster, and toe settings to the manufacturer’s specifications.
3. Test drive to verify improvement in handling and stability.
