- Tire pressure gauge
- Torque wrench
- Wheel balance weights
- Alignment tools
Raise the vehicle using jack stands and ensure it is securely supported.

2. Tire Inspection and Balancing

Remove the tires from the vehicle using a socket set.
Inspect tires for uneven wear, bulges, or damage. Replace if necessary.
Check tire pressure with a gauge and inflate to the recommended PSI.
Balance the tires using a tire balancing machine. Add weights as needed.
Reinstall the tires, ensuring they are torqued to the manufacturer's specifications (typically 100-120 Nm).

3. Wheel Alignment

Measure the alignment angles using alignment tools.
Adjust camber, caster, and toe settings to meet manufacturer specifications.
Test drive the vehicle to confirm the alignment is correct.

4. Suspension and Wheel Bearing Inspection

Visually inspect all suspension components, including control arms, bushings, and struts.
Check for play in the wheel bearings by grasping the wheel at 12 and 6 o’clock positions and rocking. Replace any worn bearings.
Tighten or replace any loose or damaged suspension components as necessary.
