2. Tire Inspection

Sub-steps:
1. Remove hubcaps or wheel covers if applicable.
2. Inspect each tire for uneven wear patterns, bulges, or cracks.
3. Check pressure using a tire gauge and inflate to recommended PSI if necessary.
Tools Required: Tire pressure gauge, tire inflator.

3. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a socket set.
2. Take the wheels to a tire shop for balancing; they will use a balancing machine to adjust weights.
3. Reinstall the wheels on the vehicle, ensuring proper torque (typically 80-100 ft-lbs, refer to manufacturer specifications).
Tools Required: Socket set, torque wrench.

4. Suspension Inspection

Sub-steps:
1. Visually inspect all suspension components for wear or damage.
2. Check shock absorbers for leaks or signs of failure.
3. Replace any damaged components (e.g., bushings or shocks).
Tools Required: Wrench set, jack and jack stands.
