Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, wheel alignment machine.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery if any electrical components will be accessed.

2. Tire Pressure Adjustment

Sub-steps:
1. Remove the valve caps from all tires.
2. Use a tire pressure gauge to measure the pressure in each tire.
3. Inflate or deflate tires as necessary to match the manufacturer's recommended pressure (typically found on the driver's door jamb).
Safety Warnings: Ensure the vehicle is securely positioned on level ground when working on tires.

3. Wheel Alignment

Sub-steps:
1. Use a wheel alignment machine to measure the camber, caster, and toe angles.
2. Adjust the alignment settings according to the manufacturer's specifications.
3. Tighten all adjustment bolts to the specified torque values using a torque wrench.
Safety Warnings: Follow safety protocols when using alignment equipment.

4. Suspension Inspection and Repair

Sub-steps:
1. Visually inspect all suspension components for signs of wear or damage.
2. If any components (e.g., tie rods, ball joints) are damaged, replace them with OEM parts.
3. Reassemble any removed components and ensure all fasteners are torqued to specifications.
Parts Required: Tie rods, ball joints, or suspension bushings (as needed).
