Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, torque wrench, OBD-II scanner
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Pressure Adjustment

Check Tire Pressure:
- Use a tire pressure gauge to check all tires.
- Inflate or deflate tires to the manufacturer's recommended pressure found on the driver’s side door jamb.
Inspect Tire Condition:
- Look for signs of uneven wear, cracks, or bulges.
- Replace any damaged tires.

3. Suspension Component Inspection

Visual Inspection:
- Check for leaks in shocks or struts, and inspect for any physical damage.
- Ensure that all suspension bushings are intact and free of cracks.
Shock/Strut Test:
- Push down on each corner of the vehicle to assess rebound. The vehicle should settle back without excessive bouncing.

4. Wheel Alignment Adjustment

Alignment Check:
- If the vehicle pulls to one side or if tire wear is uneven, perform a wheel alignment.
- Use a professional alignment machine or consult a specialist for precise adjustments.

5. Suspension Replacement (if necessary)

If any suspension components are faulty, replace them as follows:
- Shocks/Struts Replacement:
  1. Lift the vehicle and secure it on jack stands.
  2. Remove the wheels to access the shocks/struts.
  3. Unbolt the upper and lower mounting points of the strut/shock assembly.
  4. Replace with new components and torque bolts to manufacturer specifications.
- Bushings Replacement:
  1. Remove any components obstructing access to the bushings.
  2. Use a bushing removal tool to replace old bushings with new ones.
  3. Reassemble and torque all bolts properly.
