2. Inspect and Replace Tires (if necessary)

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheels using a socket set.
3. Inspect each tire for damage or uneven wear.
4. If tires are damaged or excessively worn, replace them with new tires of the same specifications.
5. Reinstall the wheels and hand-tighten the lug nuts.

3. Balance Wheels

Sub-steps:
1. Mount the wheels on a wheel balancer.
2. Rotate the wheels to identify heavy spots.
3. Attach balancing weights as indicated by the balancer.
4. Recheck for balance after adjustments.

4. Inspect and Repair Suspension

Sub-steps:
1. Visually inspect suspension components for wear or damage.
2. Replace any worn parts (e.g., control arms, tie rods) using appropriate tools.
3. Torque all fasteners to manufacturer specifications.

5. Perform Wheel Alignment

Sub-steps:
1. Place the vehicle on an alignment rack.
2. Measure the alignment angles (camber, caster, toe).
3. Adjust the angles to meet the manufacturer's specifications.
4. Test the alignment after adjustments are made.
