1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, lug wrench, wheel balancer, alignment tools.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the 12V battery for safety while working on the vehicle.

2. Tire Inspection

Sub-steps:
1. Remove all four tires using the lug wrench.
2. Visually inspect each tire for signs of damage, bulges, or uneven wear.
3. Use a tire pressure gauge to check the pressure in each tire and inflate as necessary.

3. Wheel Balancing

Sub-steps:
1. Mount each tire on a wheel balancer.
2. Spin the tire to identify imbalances.
3. Add wheel weights as needed to achieve balance according to specifications.
4. Repeat for all four tires.

4. Suspension Inspection
