Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake.
Disconnect the battery if any electrical components will be serviced.

2. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor.
Check and adjust the tire pressure to the recommended PSI as indicated in the owner's manual.
Inspect the tires for any visible bulges or punctures.

3. Wheel Alignment

Tools Required: Alignment rack, torque wrench.
Raise the vehicle using a hydraulic lift or jack stands.
Remove the wheel covers if necessary and use the alignment rack to check angles (camber, caster, toe).
Adjust alignment settings to meet manufacturer's specifications, typically:
- Front Camber: -0.5° to -1.5°
- Front Toe: 0.05° to 0.15°
- Rear Camber: -1.0° to -2.0°
- Rear Toe: 0.1° to 0.2°
Torque all related fasteners to the manufacturer’s specifications (usually around 85-100 ft-lbs for suspension components).

4. Suspension Inspection

Tools Required: Socket set, pry bar, multimeter (if electronic components are involved).
Inspect control arms, bushings, struts, and shocks for any signs of wear or damage.
Replace any damaged components as necessary.
Check for any loose bolts or nuts and tighten to specification.
