3. Check tread depth using a tread depth gauge.
Tools Required: Tire pressure gauge, tread depth gauge.
Safety Warnings: Ensure the vehicle is on level ground and properly secured before inspecting tires.

2. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a lug wrench.
2. Place wheels on a wheel balancer and spin to identify unbalanced areas.
3. Attach wheel weights to correct any imbalance found.
4. Reinstall wheels, tightening lug nuts to the manufacturer's specified torque.
Tools Required: Lug wrench, wheel balancer, wheel weights.
Safety Warnings: Always use jack stands when lifting the vehicle to ensure stability.

3. Suspension Inspection and Repair

Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Inspect suspension components for visible damage or excessive wear (check bushings, struts, and shocks).
