Solution

1. Preparation

Gather tools such as a jack, jack stands, tire pressure gauge, and basic hand tools.
Ensure the vehicle is on a level surface, and gather safety equipment (gloves, goggles).

2. Tire Inspection and Adjustment

Check Tire Pressure:
- Use a tire pressure gauge to measure the pressure.
- Inflate or deflate tires to the recommended PSI as per the manufacturer’s specifications.
Inspect Tires:
- Look for uneven wear patterns, bulges, or punctures.
- Replace tires if any significant damage or wear is found.

3. Suspension Component Inspection

Visual Inspection:
- Raise the vehicle using a jack, secure with jack stands.
- Inspect struts and shocks for leaks or physical damage.
Check Springs and Bushings:
- Look for broken or sagging springs.
- Inspect bushings for cracks or deterioration.

4. Repair or Replacement of Components

Replace Damaged Shocks/Struts:
- Remove the wheel to access the suspension components.
- Unbolt and carefully remove the damaged shock or strut.
- Install the new component, ensuring all bolts are torqued to manufacturer specifications.
Replace Springs or Bushings if Necessary:
- If springs are broken, remove them while ensuring proper safety measures.
- Replace with new springs and ensure proper seating.
- If bushings are worn, press out the old bushings and install new ones.

5. Alignment

After all repairs, take the vehicle for a proper wheel alignment.
Use a professional alignment machine to ensure all wheels are properly aligned.
